Introduction

Iggesund Paperboard manufactures a range of paperboard products at Iggesund in Sweden and Workington in England together with plastic extrusions and laminations for paperboard at Strömsbruk in Sweden. These facilities have been paperboard production units for the better part of a century thus advancing the craft, skill and tradition of paperboard manufacture.

One tonne – knowledge included

To achieve the best results in the printing process or in packaging manufacture, you need not only a high-quality base material but also knowledge about how to use that material in the best possible way. Designers, packaging developers and printers all contribute their own specific knowledge and experience to help optimise the product’s properties and functions throughout its lifespan. For this reason, hands-on knowledge about the special properties of paperboard is also required.

For a number of decades, Iggesund Paperboard has systematically compiled and made available to its customers an extensive body of knowledge material – the Iggesund Anchor – in order to help increase the user’s ability to make the best use of Invercote and Incada at all stages.

The companyAll sales of Iggesund Paperboard’s products in Europe are coordinated at our sales office in Amsterdam. We also have sales offices in Singapore, Hong Kong, Japan and the United States, as well as in Iggesund. We have organised our resources of people, technology and systems to suit our customers’ priorities and offer our customers complete commercial and technical customer support. Customers’ needs are constantly evolving and market conditions are ever changing. The service we provide is based on some simple principles: · Locally based account managers and technical service managers. Account coordinators in the sales office in Amsterdam

speak the local languages. · Sheeting facilities close to our main markets, as well as at our mills, ensure the rapid delivery of small orders. · Distribution centres close to our customers. · A wide network of selected merchants supplement direct mill orders.

The product familiesOur goal is to offer virgin fibre-based paperboard that meets the demands of our customers, the consumers and the authorities. Our product range consists of Invercote and Incada. They are also offered extruded and/or laminated with different plastics and foils.

Quality assuranceWe have implemented Quality Assurance Systems to maintain our product quality and to meet customer needs and expectations. At our mills we have certified quality assurance systems in accordance with ISO 9001 and ISO 14001. The systems are documented in our Quality Manuals and are open for quality audits by customers.Product specifications and contracts are essential elements for ensuring that we have agreements between our customers and ourselves, which meet the need for clear joint understandings about product quality and safety.

Accredited LaboratoryOur Laboratory for Sensory and Chemical Analyses is accredited for sensory measurements by the Swedish National Accreditation Authority, SWEDAC. This guarantees that tests are objectively carried out using approved and tested methods. The laboratory performs sensory analysis using statistical calibration and chemical analysis using a gas chromatograph with an odour detector and mass spectrometry. It has unique equipment for taking gas samples at room temperature and has developed methods for measuring the effects of aromas on packaging material/permeability. The laboratory’s capacity is continously used to safeguard the taint and odour neutrality of raw materials and the baseboard. It is often consulted by third parties in investigations in taint and odour problems. Accreditation number: 1740 ISO/IEC 17025.


Introduction

Product safetyThe essential purpose of packaging is to ensure the hygiene and quality of the packed product. We control the entire pulp and paperboard chain production so that we can supply paperboard products which meet strict standards for hygiene, barrier functions and taint and odour neutrality. All materials used in the making of our board are approved for food contact in accordance with current regulations in different countries.To ensure that we are providing the correct product and product safety documentation we must know the intended final application.

If the customer applications require product safety certificates or if further information is needed, please contact your local Technical Service Manager.

Compliance, accreditations and awards

Packaging in general, paperboard and paperboard making processes are all subject to environmental attention. As a paperboard supplier Iggesund takes responsibility for the environmental impact of our products from the sourcing of our raw materials through our manufacturing processes.

Environmental management systems are implemented at all our mills (ISO 14001). The Holmen Group´s forest management routines are approved in accordance with the FSC® and PEFC standards as well as certified in accordance with the ISO 14001 standard. Both our mills hold chain of custody-certifications (CoC) in accordance with FSC and Iggesunds Bruk also holds CoC certification with PEFC. This enables our certified customers to be part of the chain.

Our aim is that our processes will meet environmental requirements with good safety margins and we ensure that our products are safe for handling and use. Both mills operate in accordance with the energy management system standard ISO 50001 and the Occupational Health and Safety Management System, OHSAS 18001.

Packaging waste and associated landfill issues are of major concern in some countries. For a long time used paper and paperboard have proven to be easy to recover – both as a raw material for recycled fibre products and increasingly for energy recovery. Iggesund’s energy use is based on biofuels and we have initiated programmes to further reduce the use of fossil fuels, thereby reducing fossil carbon dioxide emissions.

Paperboard has a low carbon footprint compared to other packaging materials. The raw material, timber, is harvested from managed forests that absorb carbon dioxide and emit oxygen. Because no uniform methods of measuring carbon footprint exist, we refrain from making any claims.

The Holmen Group, to which Iggesund belongs, has been part of the UN Global Compact and its correspond-ing Nordic network since 2007. Each year the Group reports its sustainability work according to the ten principles of the Global Compact. The principles relate to human rights, social conditions, the right to establish trade unions, environmental responsibility and anti-corruption.The UN Global Compact 100 (GC100) is a global stock index that tracks compliance with the ten sustainability principles and combines this with the companies’ financial perform-ance. The 100 companies around the world judged to be the best at creating good returns through sustainable business practices are listed on the GC100 index. Holmen held GC100 status in 2013 and 2014.

Twice in the last decade, Holmen has been included in the Corporate Knights index over the 100 most sustainable companies in the world, Global 100.

The Carbon Disclosure Project (CDP) is the name of an international federation that in 2016 represented 827 institutional investors with assets totalling around SEK 900 billion. CDP seeks to encourage companies around the world to reduce their impact on the climate and nature’s resources, and it presents an annual report on the outcome of its work. As a result of its energy investments and the consequent fall in carbon dioxide emissions, in 2014 Holmen qualified for the A list on the Climate Performance Leadership Index. The global index lists 187 companies that have been shown to have an excellent strategy for reducing climate change.

Introduction

Sustainability the Iggesund Way

The overall pictureInvercote and Incada, the two paperboard families manufactured by Iggesund Paperboard, meet a very high standard from a sustainability viewpoint. They are produced in modern, efficient mills that operate largely on bioenergy. From a wider perspective, it is also obvious that the raw material is renewable and the products are well suited to recycling. In the European recycling system over 65 per cent of paper-based products are collected and recycled as material or energy.

Responsible use of resources At Iggesund’s mills, in Iggesund, Sweden and Workington, England, almost 100 per cent of the wood raw material is used. What does not become paperboard becomes energy. Both mills have minimal amounts of waste that goes to landfill – over the years the company has found applications for all the fractions previously considered to be waste.

TransparencyIggesund Paperboard is part of the forest industry group Holmen, which has repeatedly been singled out by various institutions as one of the world’s 100 most sustainable companies and a role model in fighting climate change. An extensive sustainability audit enables all stakeholders to inspect in detail how the group, and thereby also Iggesund Paperboard, performs. The sustainability audit is done in accordance with the guidelines set by the Global Reporting Initiative (GRI).The ultimate transparency is created when our customers and the general public are able to roam freely in our forests and see with their own eyes how they are managed.

The most sustainable material systemPaperboard and paper products are included in a material system in which paper is collected after its primary use, is recycled and can be used again. Perhaps not always in the same applications as the primary fibre but there are many sensible applications for recycled-fibre-based material.However, primary and recycled fibres are not two separate systems. On the contrary, they are mutually dependent. If the inflow of primary fibre ceases, the industry that lives on recycled fibres starts to experience disruptions after only a few months. According to the consulting firm McKinsey, the large-scale addition of primary fibres is required to maintain the quality of the global recycled fibre pool.

How is paperboard tested? Which EU regulations apply to paperboard material? What kind of pallets can the paperboard be delivered on?

General Technical Information is a collection of technical information designed to give customers a general picture about everything from testing to delivery forms, information that can ultimately affect the end result both in terms of productivity and function.

The information includes an overview of various kinds of paperboard and advice about how the paperboard material should be handled before it is used. We hope that these recommendations and advice will make it easier to use Invercote and Incada.

At www.iggesund.com we are gradually making our infomation material “The Iggesund Anchor Material” available and searchable for everyone who would like even more detailed information about both the technical and aesthetic aspects of paperboard.



Paperboard handling

The correct handling of paperboard is very important for achieving the best results in printing, converting and use. To ensure this Iggesund Paperboard recommends the following procedures to printers, converters and users.

Recommendations to printers/convertersBefore printingThe paperboard is identified by the order number and the pallet or reel number. It is essential that these numbers are recorded to provide identity and traceability throughout printing, conversion and use, or that you keep the labels until the job is finished. In the case of doubt about the performance of the paperboard or its compliance with specifications, it is a requirement to provide this information and relevant samples to Iggesund Paperboard.

During printing/convertingThe moisture-proof wrapping must not be removed until the board has attained the temperature of the environment concerned (printing room etc):

Pallet or reel weight (kg)

Temperature differences board – printing room (print room temp. about 20°C)

10°C 20°C 30°C

400 2 days 2 days 3 days



When cold paperboard is exposed to a warm environment the air adjacent to the board can be cooled below its dew point (point of condensation) and this moisture is then absorbed by the board. The time for temperature equilibrium to be established varies depending on the temperature difference and the weight of the board (pallet or reel). Therefore the wrapper should never be removed before the board has reached the temperature in the printing room.

Recommended climate in the printing/converting room to prevent curl and/or misregister is 45–60 % relative humidity and a temperature of 20–23°C.

The moisture content of paperboard can rise as a result of its exposure to air at high relative humidities, during periods of wet weather. It can also occur as a result of the condensation effect in cold weather discussed above. The result of moisture absorption can be waviness at the edges of the sheets and a general tendency for upcurl i.e. curl towards the print surface. If wavy sheets of board are printed creases may occur at the back edges of the sheets as they pass through the offset press, misregister may occur, together with press misfeeding, wasted sheets and loss of output and efficiency. A paperboard which has a high moisture content also becomes tough and difficult to cut.

The moisture content of paperboard can fall as a result of its exposure to air at low relative humidity. This can occur during very dry weather and also occur in centrally heated buildings when the external air is very dry and very cold. A paperboard which is too dry may also become wavy, develop downcurl i.e. curl towards reverse side of the board and become brittle. These features can cause misfeeding and the board will be difficult to crease satisfactorily.

Avoid rubbing or touching the surface of extruded/ laminated board because the corona treatment is easily damaged.



After printing/convertingPaperboard in sheet form should be rewrapped with moisture-proof material after printing.

Rewrapping is particularly important in order to ensure good register when board is printed in two or more passes through the printing press. It is also important to wrap in this way to achieve good register between the print and the next process e.g. cutting and creasing, guillotining or bookbinding.

Paperboard products should be wrapped in moisture resistant material after conversion and prior to shipment to the customer (end-user) or to further conversion operations.

Recommendations to end usersBefore useThe supplier´s order number identifies the material. For the purpose of subsequent traceability, should this be necessary, we recommend that you should record this number and maintain the identification of the material.

Unpacking/StorageThe end user should also observe the precautions regarding the achievement of temperature equilibrium prior to unwrapping and use, see warming up time table on previous page. Unused material should be rewrapped.

The end user should rewrap any unused material which would otherwise be exposed to the atmosphere of the work environment for an extended period. Some end users, as a consequence of their process, may have environments which are either excessively damp or excessively dry compared with the range of 45–60 % relative humidity, and in such conditions there would be a tendency for the board to either gain or lose moisture with a consequent change in shape or loss of flatness.

Recommendation of time limit for board in storeIggesund Paperboard has chosen raw material, chemicals and processes which will support stable and long life-time of the manufactured products, without deterioration of the board properties. However, even if the board is correctly handled optical as well as physical properties may change with time. Iggesund Paperboard recommend a maximum of 1 (one) year time limit, from delivery, for board in store. For plastic coatings and laminations see specific recommendations, in sections “Plastic coatings” and “Foil and film laminates”.

When uncertain whether to use board or not beyond the recommended maximum year time limit which is often possible, please contact your Technical Service representive for advice.

It is not always possible to deliver certain sheet sizes as single pallets. The option will be twin pallets with the codes 2CDL, 2CDS, 2DFL and 2DFS.

Transport packagingTransport packaging is used to maintain the quality of the delivered paperboard and to protect it during handling, transport and storage.

Reels have cores made from recycled paper and core plugs from particle wood. The reels are either packed with end protecting corrugated kraft board coated with a water barrier (polyethylene 15 g/m²) and stretch wrap or only stretch wrapped. The stretch film is low-density polyethylene. The labels are made of bleached kraft paper, occasionally plastic labels are used.

Pallet packs consist of pallets of 100% wood covered with a protective polyethylene sheet. The paperboard pile is protected on top by a sheet of polyethylene. The whole pallet is then shrink-wrapped with medium-density polyethylene. Labels are made of bleached kraft paper.

Ream packs are made from bleached kraft paper coated with a water barrier (polyethylene 10 g/m²). Labels are made of bleached kraft paper. The materials used for the transport packaging meet the requirements in the EU Directive EC 94/62. For more detailed information please contact your Iggesund Paperboard representative.

Test methods

GeneralThis section contains an alphabetical list of the tests by which paperboard is evaluated during manufacture. The list is divided into two parts · Paperboard property tests · Extrusion/lamination property tests

These test methods evaluate the board properties which influence the appearance and performance. Important test values (technical data) for the individual board products are quoted on the board data sheets in the sections Paperboard products, Plastic coatings and Foil and film laminates.

The board making process is described in the document Paperboard – the Iggesund Way, which also explains which aspects of the process are responsible for specific board properties.

The Paperboard Reference Manual deals in further detail with the board properties in terms of appearance and performance, and how they influence the printing, converting and use of the board.

Paperboard property tests

All properties are measured in test climate 23°C/50% RH at the mills. Board performance properties are measured on samples taken ex board machine.

Bending Bending stiffness, bending resistance and bending moment, see Stiffness.

Brightness See Optical properties.

Caliper See Thickness.

Cobb test See Water absorption.

Colour See Optical properties.

Gloss The gloss of the paperboard surface is measured in accordance with ISO 8254-11). The gloss is expressed in % units. The surface of the board is illuminated at an angle of 75° and the reflection from the surface is recorded by a photo-electric cell.

Within Iggesund Paperboard a surface having a measured value < 40% board gloss is regarded as matt. A medium gloss board is in the range ≥ 40% to < 70%, and a high gloss board has a value of ≥ 70%.

Grammage The grammage of the paperboard is assessed in accordance with ISO 5361). Grammage expresses weight per unit area and is measured in g/m².

Ink absorption Ink absorption is measured using an internal test method. The ink absorption is expressed in % units. A specific ink is applied to the paperboard surface. The amount of ink absorbed in a given time is assessed by % reflectance compared with the unprinted surface. Porométrique ink No. 3809 from Lorilleux is used for the testing of ink absorption.

Interlayer strength See Ply bond.

Moisture content The absolute moisture content is measured in accordance with ISO 2871). It is expressed in % of the paperboard weight. The moisture content of the board is measured continuously on line on the board machine and recorded.

Opacity The opacity of the paperboard is assessed in accordance with ISO 24711). The measuring principle is based on comparison of reflectance for a single paperboard sheet over a black background compared to an opaque pack of paperboard samples. Opacity is expressed in % units and readings close to 100 mean no show through.

Optical properties The term whiteness is often used as a comprehensive expression for some of the optical properties of the surface of paperboard, although whiteness is also a specific value that is measured today. The properties quoted here are CIE-whiteness, Brightness and Colour.

Where paperboards include fluorescent whitening agents or FWA’s (sometimes referred to as optical brightening agents or OBA’s) measurements are made using an illuminant that contains a controlled element of ultra violet (UV) light.

All values are measured at both Iggesunds Bruk and Workington using Datacolor Elrepho instruments.

Optical properties, CIE-whiteness CIE-whiteness (W) is a comprehensive term used to express the visual impact of near white surfaces by means of a single value. This value, based on CIE (Commission Internationale de l’Eclairage) tristimulus values, describes perceived whiteness in outdoor UV-rich illumination. A large number of equations have been developed to calculate whiteness, but CIE-whiteness is perhaps the most commonly used. CIE-whiteness is measured in accordance with ISO 114751).

Optical properties, ISO Brightness This is the diffuse blue reflectance factor measured at an effective wavelength of 457 nm. As the measurement is only carried out in the blue region of the spectrum it is of limited usefulness. ISO Brightness is measured in accordance with ISO 24701).

Optical properties, Colour To quantify the impression of colour to the human eye of a nearly white surface, the CIE colour space can be used. Three reflectance figures L*, a* and b* known as the CIELAB coordinates are measured using a standard light source. The coordinates a* and b* measure colour. Positive figures for a* express redness, negative figures greenness, and positive figures for b* express yellowness, negative figures blueness. L* is a percentage which measures luminance on a scale where black is zero and pure white is usually 100%. Colour is measured in accordance with ISO 5631-21).

Ply bond The interply or interlayer strength of the paperboard is measured in accordance with TAPPI 5691). Ply bond is measured using a Scott Bond type tester and is expressed in J/m2.

Smoothness See Surface roughness.

Stiffness A number of methods of measuring stiffness are recognised. Values for the following methods are quoted in this catalogue:

· Bending stiffness L & W 5° · Bending resistance L & W 15° · Bending moment Taber 15°




Since the stiffness is related to the orientation of fibres in the sheet during manufacture, two values are given: for the machine direction (MD) and the cross direction (CD).

Stiffness, Bending stiffness L & W 5° Bending stiffness L & W 5° is measured in accordance with ISO 56281), DIN 53 1211). The bending stiffness is expressed in mNm.

Stiffness, Bending resistance L & W 15° Bending resistance is measured in accordance with ISO 24931). The bending resistance is expressed in mN.

Stiffness, Bending moment Taber 15° Bending moment is measured in accordance with ISO 24931). If the bending moment is expressed in mNm, the following relationships apply: Bending moment (Taber 15°) = Bending resistance (L & W 15°) x 0.0483Bending resistance (L & W 15°) = Bending moment (Taber 15°) x 20.70 Note: If Taber is expressed in gcm the following conversion applies: Taber in mNm = Taber in gcm x 0.0981

Surface pH Surface pH is measured on a water extract. It is expressed in pH units on a scale of 0 –14.

The pH scale

Surface roughness Surface roughness is measured in accordance with ISO 8791-4, using the Parker Print Surf Roughness tester (PPS) at 1000 kPa using a soft backing (S10). The surface roughness is expressed in µm. Lower results indicate smoother surfaces.

Uncoated surfaces are measured using the Bendtsen method and the roughness is expressed in ml/min. Lower results indicate smoother surfaces.

Surface strength The surface strength is measured in accordance with ISO 37831). The strength is expressed in m/s. This test evaluates the ability of the surface to withstand picking and blistering and is carried out using an IGT Printability Tester using a medium viscosity oil. Where strength is expressed in N/m the following correlation applies.

Taint and odour Taint and odour is assessed by members of trained panels assigning numerical ratings and recording their impressions of tainting flavours or volatile smells experienced. All our paperboard products are tested by the Robinson taint test based on DIN 10 9551). As the Robinson test is based on a comparative assessment using a panel, the results between laboratories, and even within laboratories, may not necessarily be reproducible.

GC (Gas Chromatographic) and Mass Spectrometer methods are used for assessing and identifying paperboard components and those arising from printing and conversion processes.

Our laboratory for sensory and chemical analyses is accredited for sensory analyses with the accreditation number 1740. Accredited laboratories are appointed by the Swedish Board for Technical Accreditation (SWEDAC). The Swedish accredited laboratories meet the requirements laid down in the European standards EN 45001, and EN 45002 as well as their international equivalent ISO/IEC Guide 25.

Tearing resistance The measured force required to tear a paperboard sheet is given for machine direction (MD) and cross direction (CD) respectively. Tearing resistance is measured in accordance with ISO 19741) and is expressed in mN.

Tensile strength The tensile strength is the force required to rupture a strip of paperboard. Values are given for machine direction (MD) and cross direction (CD) respectively. The tensile strength is measured in accordance with ISO 1924-21) and is expressed in kN/m.

Thickness The paperboard thickness is measured in accordance with ISO 5341). The thickness is expressed in µm. Caliper (pts) is also recorded for reference on specification sheets, where pts are inches/1000.

Water absorption, Cobb test The surface water absorption is measured using the Cobb test in accordance with ISO 5351). The water absorption is expressed in g/m².

Water absorption, Wick test Water absorption at the paperboard edge is measured using a Wick test. The paperboard surface is sealed with waterproof tape on both sides. The sample is weighed, placed in water at 80°C for 20 minutes and reweighed. The amount of water absorbed by wicking is expressed in kg/m².

Whiteness See Optical properties.

Wick test See Water absorption.

Extrusion/lamination property testsAdhesion See Surface strength.

Grammage Coat weight is measured continuously along and across the board web. It is expressed in g/m2 and can be used for calculating the coating thickness.

Pin holes Pin holes are microscopic holes that might appear in the plastic film during the coating process. These are very small; they are not visible to the human eye. A limited number of pin holes are of no importance in most cases. Pin holes are determined by exposing the plastic coating to dyed alcohol for a certain period of time and counting the number of coloured specks. The presence of pin holes is expressed in number/m2.

Surface roughness Surface roughness is measured using the Parker Print Surf Roughness Tester. The surface roughness is expressed in µm. Lower results indicate smoother surfaces.

Surface tension See Wettability.

Surface strength Plastic adhesion (surface strength) is a dimensionless property defining the relation between adhesive and cohesive strength in the board surface. The internal method involves pulling a strip off the coating of the board and determining the degree of failure in the interlayer. Adhesion is also measured as peel strength at 125° angle and is expressed as N/cm width.

Wettability The wettability of a surface decides whether a printing ink or a glue will stay on and adhere to a surface. It is measured as the surface tension of a standard liquid which just wets the plastic surface. Surface tension is expressed in dynes/cm. The surface tension of a plastic surface is usually too low for printing or glueing. The surface is therefore corona treated to improve the wettability.




Products and use

Product performanceDemands for promotion and protection define the performance characteristics of paperboard, as do the requirements during conversion and distribution. The overall demand for minimum use, resource efficiency, competitive products and efficient systems requires paperboard with high performance combined with good fitness for use.

Iggesund Paperboard products are developed to provide high performance for the specific uses. In marketing, sales and technical service fitness for use and performance requirements are matched to ensure efficient solutions for each use. More information is found in the Paperboard Reference Manual.

Standard product specification and traceabilityAll products are manufactured to meet the specifications as described in the sections Paperboard Products, Board Laminates, Plastic coatings and Foil and film laminaties in the Product Catalogue. Review of the specifications is documented and performed according to the procedures in the Quality Management Systems within Iggesund Paperboard.

The correct application of specification tolerances provides the printer, converter and ultimately the end-user with the assurance that the paperboard supplied has been produced under carefully controlled conditions in order to meet market quality requirements. In the manufacture of its products Iggesund Paperboard continuously strives to minimise deviations from specified target values. To meet our customers’ demands for quality and consistency we also specify upper and lower tolerances as appropriate. In the control of product quality Iggesund Paperboard uses on-line as well as laboratory measurements to monitor on at least a minute by minute and also hourly basis, according to documented procedures.

Our guaranteeIggesund Paperboard guarantees that the material our customers receive has been assessed by sampling using both on-line and laboratory techniques. Quality parameters and all sample measurements are based on samples taken ex board machine and have been found to be within the published and agreed tolerances as detailed in the current edition of the Paperboard Product Catalogue or approved amendment. Iggesund strongly recommend the full testing of the product at every stage through the supply chain before going into full production. Your local Technical Service contact should be involved to achieve maximum product performance.

In situations where there are doubts about the performance of the paperboard or compliance with the specifications, tools are available to trace information related to the product and/or order. The Iggesund Paperboard document Terms and Conditions of Trade 2015 constitutes the whole agreement between Iggesund Paperboard (Seller) and the Buyer and here it is stressed that in the case of a claim, the clear identification of the goods is a requirement. This is to enable above mentioned traceability to relevant product data. For the customer, the key to traceable information is the order number and package number as this information is the link to all product data and laboratory and machine records. Retrievable data are stored for a minimum of two years. Procedures and systems are in place to achieve the necessary traceability back to Iggesund Paperboard´s suppliers.

Taint and odour neutralityThe Swedish Board for Technical Accreditation has accredited our laboratory for sensory and chemical analyses. Measurements are made under the auspices of a government agency and with the obligation to be impartial, making this the most stringent form of quality assurance. Most countries in the world accept test results that have been carried out at accredited laboratories and these can therefore be compared.

To ensure that our paperboard meets the demands for taint and odour neutrality, we regularly monitor production using organoleptic test procedures and our own fully trained assessment panel. We guarantee that our baseboard products Incada and Invercote register Robinson taint values according to EN1230 and DIN 10955 that are below the detection limit 0.6.

As an integral part of our product quality assurance policy, Iggesund Paperboard accepts responsibility for taint and odour problems proven to have been caused by our products.



Purity and hygieneFor end uses such as food, confectionery and pharmaceuticals, purity and hygiene are of critical importance. In order to maintain correct product performance Iggesund Paperboard only uses approved raw materials and additives, and carries out the production process according to good manufacturing practices that incorporate the use of risk assessment methods. Every chemical additive is assessed according to occupational health and safety, environmental impact and product safety before it is allowed to be used. Strömsbruk, supplying barrier-coated paperboard for many food end-uses, has a complete hygiene system in operation. For our paperboard mills, Iggesund and Workington, we have implemented the CEPI GMP, which is more demanding than the EU GMP regulation (EC 2023/2006) and also includes a risk analysis.

Product labellingPresently there are several labelling schemes on the market that claim to communicate representative facts about products´ performance and environmental acceptability (eco-labels). Iggesund Paperboard considers these schemes and labels too incomplete and subjective to provide a relevant assessment of paperboard products and their use. The international development of Environmental Product Declarations seems promising, but until these are developed and become an accepted standard, reference is made to the environmental fact sheets in Annual Report at www.holmen.com.

Product safety and liability The essence of packaging is to ensure the quality, hygiene and safety of the packed product. To ensure these a number of national and international rules and regulations must be met. In addition, company and product specific measures are usually added. The final goal is to secure fitness for the intended use. It is important to protect the packed product against contamination from the outside and sometimes from direct contact with the paperboard surface. Iggesund Paperboard products are therefore made only from high quality primary fibres and functional additives which ensures safety, hygiene and good organoleptic properties. Where necessary additional barrier materials can be used to ensure that the quality of a packed product can be safely maintained until it is used.

In many countries, the consumer safety is protected by product liability legislation with far reaching consequences for the supply chain. In the event of damage all actors along the chain are responsible to the consumer (joint and separate responsibility). The only exception is when you can prove, for your own area of responsibility, the fulfilment of the relevant requirements. A key consequence is thus to ensure the complete understanding and verification between supplier and customer of all the relevant aspects.

Product safety certificateIggesund Paperboard will on request issue a product declaration to verify the fitness and safety for the intended use. The document is issued after having carefully checked that the intended use of a specific paperboard product, under specified conditions of use, will not endanger the quality and safety of the packed product. The specific statements in the declaration are integral parts of the Iggesund Paperboard Management Systems. The given information is valid for two years or until further notice.



Rules, regulations and good manufacturing practiseFor certain geographical areas or specific end-uses, additional requirements must be met or barrier functions are needed. Iggesund Paperboard will ensure that the appropriate product/barrier combinations fulfil the requirements for the intended use. Barrier functions are generally achieved by plastic coating. The plastic itself, in all plastic coatings, meets the requirements of the EC Plastics Implementation Measure (PIM) Regulation 10/2011/EC and its amendments. For plastic coating/lamination only raw materials which are suitable for the specific application are used. The status in this respect is updated every year. Analysis of total migration tests are regularly made to verify compliance. All Invercote and Incada products are in compliance with the EU Regulation 1907/2006/EC (REACH) guaranteeing that the content of SVHC (Substances of Very High Concern) is lower than the stipulated limit of 0.1% in accordance with article 57 in the regulation.

All Iggesund Paperboard products will, subject to application/intended use, fulfil the requirements listed below:

Rules and regulationsOver the years, many countries have developed regulations mainly to control the packaging of food products and to prevent cross-contamination between the product and the packaging. The best known and currently most widely recognised regulations are summarised in the table above. In the absence of harmonised legislation Iggesund Paperboard ensures that its products fulfil the relevant requirements in the countries where the products are used.

Good manufacturing practiseThe Commission Regulation (EC) No 2023/2006 of 22 December 2006 on good manufacturing practise for materials and articles intended to come into contact with food lays down rules on good manufacturing practice. The main requirement in this regulation is that we as a manufacturer shall operate an effective quality management of our manufacturing operations. For printing inks applied to the non-food contact side of a material or article GMP should in particular ensure that substances are not transferred into food by set-off or transfer through the substrate. When the board is used for fatty or aqueous packaging applications a barrier between the board and the packed foodstuff is required.

Used products and waste management; producer responsibilityThe EU Directive on Packaging and Packaging Waste, EC94/62 and subsequent amendments, defines common requirements on packaging and packaging waste within the EU. However, the Directive’s formal implementation and interpretation and the practical methods introduced by the member countries vary widely. As a consequence the requirements and methods differ between countries. In some countries producer responsibility has been introduced and has led to industry-owned organisations which manage used packaging. In other countries, there are community or nationwide schemes more or less controlled by the authorities. The result is systems with very different approaches to how packaging is taken care of and the costs involved. Each country has its own systems and rules.

Waste generated during the manufacture of Iggesund Paperboard’s products is managed and reported according the permits given by the local authorities

The EU Directive on Packaging and Packaging Waste (EC 94/62)The EU Directive (EC94/62) is aimed at minimising the environmental impact of packaging and packaging waste. It places an obligation on prevention by source reduction, re-use or recovery of used packaging and minimisa tion of heavy metal contamination. The EU Commission gave the European Standards Organisation, CEN, a mandate to develop standards to be used as EU harmonised standards to ensure the fulfilment of the essential require ments. During 2004 CEN adopted and published the following standards: EN 13427:2004, EN 13428:2004, EN 13429:2004, EN 13430:2004 and EN 13431:2004. EN 13432:2000 was already published.

In general the following is valid for Iggesund Paperboard products: Iggesund Paperboard will act to meet all the relevant requirements of the directive, and will use the above mentioned CEN packaging standards to assess and document compliance with the essential requirements. EN 13427:2004 is called “the umbrella standard” which guides users through the texts, indicating which standards are applicable to each type of packaging. EN 13428:2004 consists of two parts of which the first covers “prevention by source reduction”, and the second “qualitative prevention by minimizing presence of noxious and hazardous substances in the packaging material”. In the areas of product development, marketing, sales and technical service, fitness for intended use is given priority to ensure that the main purposes and functions are fulfilled with a minimum of material. In the area of transport packaging the demand for prevention by source reduction is applicable and fulfilled by supplier requirements as defined in the standard. All products meet the requirements regarding determination and minimisation of noxious and hazardous substances. EN 13429:2004 regarding reusable packaging is not applicable for our products. Product design and composition is such that material recycling (EN 13430:2004) or energy recovery (EN 13431:2004) can be done without limitation. Our baseboards are intrinsically biodegradable. For the quantification regarding composting, tests should be made on the final packaging after the converting process (EN 13432:2000).

Product Overview


The Invercote family consists of a range of products customised for different end-user applications and is manufactured at the integrated Iggesund mill in Sweden. Invercote is a multilayered Solid Bleached Board (SBB), made from chemical pulp produced by the sulphate pulping method. The use of virgin fibre and the sulphate pulping method ensures a hygienic and odour- and taint neutral product. All materials used in the making of Invercote are approved for food contact according to current regulations.

The fibre composition varies for each layer in the construction. Fibres are selected based on shape and length and treated in different ways to tailor the paperboard construction to the intended use. The benefit of this multi-layered SBB compared to competing single- and dual layer products is the unique possibility of optimizing the surface fibre layers to form an excellent base for coating. The coating is applied in two or three steps to meet the smoothness demands of printing and foiling applications.

Another advantage of a multi-ply construction compared to a single ply one is that the different layers can be composed to optimise board characteristics such as stiffness and strength, thus ensuring both productivity in converting operations and good function in the end product.

Invercote products are widely used for picture postcards, high-quality brochures and book covers, and the packaging of cosmetics, perfumes, chocolate, pharmaceutical and tobacco products. Invercote is manufactured from fibre of known and traceable origin and produced at a site where pulp production is integrated with the paperboard mill. This combined with the inherent stability of our chosen manufacturing process ensures a repeatable and predictable performance of the product in converting and use.

Invercote in use

The fully coated printing surfaces of the Invercote family are designed to meet the highest demands of image reproduction in printing and surface treatment methods such as hot-foil, foil- and film application. The coating composition is adjusted in two different general directions for the product family to satisfy printability requirements, primarily of offset-litho and gravure printing. Inks on the market intended for use on fully coated surfaces can be used on the full range of Invercote products. Invercote can be printed in offset-litho, gravure, flexo, screen, and digital printing processes. Invercote products are not suitable for web-offset or heatset printing.

Adjustments in the prepress operation and the choice of ICC profiles can be done in the same way as for a fully coated fine paper. When performing repro for delicate work or if a major part of your production is running on Invercote, you may benefit from creating your own dedicated ICC profiles for Invercote in your selected process environment.

Invercote is qualified and certified for most digital printing presses (electroink, inkjet and xerography) on the market today. Invercote is suitable for all digital printing and converting applications, but due to the multitude of printing engines and the rapid development of both inks/toners and machinery, we recommend that you contact our technical service personnel for assistance. Please visit www.iggesund.com for downloads and additional information on digital printing.

Invercote can be sheet laminated over the print with cellulose acetate or oriented polypropylene (OPP) for a high gloss appearance. Invercote’s strength and inherent consistent baseboard performance will support full speed printing and post-print production. Deep and narrow creases can be achieved as well as excellent deep and detailed embossing. The strength and toughness of the fibre network does, however, make it necessary to adjust tooling and its application in post-press converting (primarily cutting, creasing and embossing) to produce the best result. Recommendations for creasing are provided in this document. With regard to knife- and embossing tool geometry, we advise you to contact your supplier.

Invercote can be glued with both emulsion (water-based) and hot melt adhesives. With both types of adhesive, initial tack, fibre tear and secure mature bonds can be achieved over a wide range of speeds and conditions of use.

Solid Bleached Board, GZ

Product description

Invercote G is designed for graphical products and prestige packaging where an exceptional aesthetic result is desired. Invercote G has a smooth surface that is tailored to faithfully reproduce the most sophisticated printed images and to meet the high demands of flawless foil and film lamination. This surface, combined with Invercote G’s excellent structural, design and embossing characteristics make it ideal for the most demanding printing applications. Invercote G is recommended for high-end graphical applications and packaging, also for aroma and flavour sensitive products.

The printing side is triple coated and the reverse side is single coated, both sides are finished to a matt level. The 180 and 200 g/m² grammage versions are produced without reverse side coating. Thanks to its composition of multiple layers of solid bleached primary fibres, Invercote G has a superior strength and toughness compared to board grades that contain mechanical or recycled fibres or single-ply bleached primary fibre board. This strength gives several advantages in carton designing and processing, in packaging operations and in the use of the package itself. A patented coating formula provides outstanding lightfastness, giving the end products a longer life. In addition to traditional printing techniques, Invercote is qualified and certified for most digital printing presses on the market today and suitable for digital finishing technology. Invercote G is also available as linen embossed sheets in all grammages.

Invercote G in the grammages 260-380 g/m² is certified as biodegradable and compostable in compliance with thedemands in the Directive EN 13432:2000.

Invercote Lenato


Product description

Invercote Lenato is designed for cigarette packaging where a high whiteness is desired. The printing side is fully coated and finished to a matt level. The smooth surface of Invercote Lenato is essential for demanding full- and half tone printing. The smoothness and uniform ink absorption characteristics are of paramount importance. Solvent retention after gravure printing is particularly low, allowing for shorter storage time after printing.

Thanks to its composition of multiple layers of solid bleached primary fibre Invercote Lenato has a superior strength and toughness compared to board grades containing mechanical or recycled fibres or single ply bleached primary fibre board. This gives several advantages in designing and processing cartons, in packaging operations and in the use of the package itself. Invercote Lenato has been developed specifically for crush cut rotary die-cutting. A printed Invercote Lenato hinge lid blank meets the exacting requirements of high speed cigarette packers. Controlled manufacturing conditions and the documented consistency gives a high runnability.

Invercote Lenato has excellent creasing and embossing properties allowing deep and narrow creases and defined multilevel embossings. The high quality embossing is also possible when performed together with hot foil stamping. The board has a Crease Resistance Recovery (CRR) adapted to the demands from the tobacco industry, allowing high speed in the packaging lines and providing excellent box geometry. This makes Invercote Lenato ideal for bevel edge- and round corner boxes.

Invercote T


Product description

Invercote T is designed for cigarette packaging and manufactured without the addition of fluorescent whitening agent, FWA. Whiteness is achieved only through the coating and the pure white fibre in the baseboard. The printing side is fully coated and finished to a matt level.

Solvent retention after gravure printing is particularly low, allowing for shorter storage time after printing. Thanks to its composition of multiple layers of solid bleached primary fibres, Invercote T has a superior strength and toughness compared to board grades containing mechanical or recycled fibres or single ply bleached primary fibre board.

The Incada family consists of products customised for different end-user applications. The product family is manufactured at the integrated mill in Workington, United Kingdom. Incada products are widely used for book covers, greeting cards, packaging of food, cosmetics, chocolate, pharmaceuticals and tobacco products.

Incada is a multilayered Folding Box Board (FBB) entirely based on virgin fibres. Specific fibre compositions are used for the various layers in the construction to optimise performance. The outer layers consist of bleached chemical sulphate pulp and the middle layers of mechanically separated fibers (RMP-pulp). Fibres for the different layers are treated in different ways to tailor the paperboard construction to the intended use. The benefits of this multilayered FBB lies in the construction itself. The outer layers of sulphate pulp with its application of a double coating provide the foundation for a smooth surface which is finished by machine glazing to meet the high demands of printing and foiling. The middle layers consisting of mechanical pulp provides high bulk and stiffness. Treatment of fibres for the middle layers in the construction are also targeted to optimise productivity in carton manufacturing, erecting and filling processes.

Incada is manufactured from virgin fibres of known and traceable origin and produced at a site where pulp production is integrated with the paperboard mill. This combined with the inherent stability of our chosen manufacturing process ensures a repeatable and predictable performance of the product for converting and use.

All Incada products are manufactured from virgin fibres and the manufacturing process is trimmed to assure best hygienic, odour and taste neutral properties. All raw materials used in the making of Incada are approved for food contact according to current regulations.

Incada in use

The fully coated printing surfaces of the Incada family are designed to meet the high demands of image reproduc-tion in printing and surface treatment methods such as hot-foil, foil- and film application for the packaging and commercial print industry. The smooth surface and fast ink-setting properties of Incada support high productivity in both printing and foil applications. Inks on the market that are designed for use on fully coated surfaces can be used on the full range of Incada products. Incada can be printed using offset-litho, gravure, flexo, screen and selected digital printing processes. Incada products are not suitable for web-offset or heatset printing.

Adjustments in the prepress operation and the choice of ICC profiles can be done in the same way as for a medium- to fully coated fine paper. When performing repro for delicate work or if a major part of your production is running on Incada, you may benefit from creating your own dedicated ICC profiles for Incada in your selected process environment.

Incada works well in most digital printing presses on the market today. Incada is suitable for many digital printing and converting applications, but due to the multitude of printing engines and the rapid development of both inks/toners and machinery, we recommend that you contact our technical service personnel for assistance.Please visit our website www.iggesund.com for downloads and additional information on digital printing.

Incada can be sheet laminated over the print with cellulose acetate or oriented polypropylene (OPP) for a high gloss appearance.

Incada’s stiffness and baseboard performance will support full speed printing and post-print production. Creasing and embossing can be performed efficiently and with good results. Recommendations for creasing are provided in this document. With regard to knife- and embossing tool geometry, we advise you to contact your supplier.

Incada can be glued with both emulsion (water-based) and hot melt adhesives. With both types of adhesive, initial tack, fibre tear and secure mature bonds can be achieved over a wide range of speeds and conditions of use.

Incada Silk


Product description

Incada Silk is designed for quality packaging and graphical applications which require outstanding visual impact. It is a fully coated white back folding box board finished to a matt level which gives excellent results in both solid print and half tone illustrations and it easily develops a high print and varnish gloss. The reverse side is single coated and finished to a matt level which gives an aesthetically pleasing appearance and provides improvements compared to an uncoated surface regarding smoothness and uniformity in ink absorption. Incada Silk is a primary fibre paperboard comprising bleached chemical pulp outer plies, mechanical pulp middle plies and carefully chosen coating ingredients which together meet the requirements for high performance in quality printing and varnishing. The fully coated finish gives a very smooth surface and meets the requirements for both demanding half tone gravure and offset litho processes, where smoothness and uniform ink absorption are of prime importance. The ink setting and drying properties also ensure good runnability in high speed offset litho processes. Incada Silk works well in most digital printing presses on the market today and is suitable for digital finishing technology.

Incada Silk T


Product description

Incada Silk T is designed for cigarette packaging and manufactured without the addition of fluorescent whitening agent (FWA). Whiteness is achieved via a combination of mechanical and chemical fibres in the base board and also the choice of coating.

Incada Silk T is a primary fibre paperboard comprising bleached chemical pulp outer plies, mechanical pulp middle plies and carefully chosen coating ingredients which together meet the requirements for high performance in quality printing and varnishing. The fully coated finish on the printing side gives a very smooth surface and meets the requirements for both demanding half tone gravure and offset litho processes, where smoothness and uniform ink absorption characteristics are of prime importance. The ink setting and drying properties ensure good runnability in high speed offset litho presses.

Incada Silk T has also been designed through its construction to give a very low solvent retention after gravure printing. The printing side is finished to a medium gloss level, whilst the reverse side is uncoated and suitable for less demanding printing applications. Incada Silk T gives excellent results in both solid print and half tone illustrations and easily develops a high print and varnish gloss.

Board laminates are made by back-to-back pasting of a baseboard. The printing surfaces of the print and reverse sides are therefore identical. Board laminations are significantly stiffer and stronger than standard board grades, and are therefore especially suitable for various display applications and different types of rigid, exclusive gift packs.

To achieve special properties it is also possible to paste the baseboards face-to-back and face-to-face. The construction of the gluing machine even allows triple or fourfold lamination. The laminated boards are available with improvements like PE (polyethylene) coating or foil-/film lamination for specific needs, such as outdoor displays or strong packaging with a special printing surface characteristics.

Converting advice

Detailed recommendations on conversion are given in the Paperboard Reference Manual.

Printing and varnishingThe print and reverse side surfaces of the products have identical printing and varnishing properties. The most frequently used printing methods are screen, sheetfed offset litho and flexography. A good print gloss is easily achieved. Inks for coated surfaces should be selected. The most frequently used types of varnish are water based, spirit and alcohol based and UV cured. A good varnish gloss is easily achieved. It is important to select UV varnishes which are compatible with the inks to be used.

Printing pressIf possible printing presses with large cylinder diameters should be used. Due to the high compressibility of the material we recommend using lower pressure than normal. This is possible because of the smooth printing surface.

Printing inksRapid setting inks are not recommended because of the large increase in ink tack that can be caused by ink drying within the printing nip. Low tack inks are recommended.

GluingBoth Invercote Duo and Incada Duo can be glued with both emulsion (water based) and hot melt adhesives. With both types of adhesive initial tack, fibre tear and secure mature bonds can be achieved over a wide range of speeds and conditions of use.

SummaryThe final print result depends on many parameters and their interaction. Other parameters that may influence the final print result are the age and compressibility of the rubber blankets, the viscosity and temperature of the ink, fountain solution water, printing speed, etc. If further advice or recommendations are needed, please contact your Technical Service Manager.

To attain specific properties, paperboard is combined with various plastics, films, foils or other additional paperboard layers. Complete descriptions of the product can be acquired by studying the specifications of the laminate together with the specifications of the paperboard product. The choice of material is determined by the desired properties. These can be barriers against moisture and grease, heat tolerance, strength or combinations of these functions.

Iggesund Paperboard representatives often participate in customers’ packaging development, thereby acquiring a broad overview of packaging solutions. Their knowledge can help determine the best solution for the product’s journey through the distribution system from manufacturer to consumer. In addition to what is presented in the catalogue, there are other products and combinations available. Contact your local Iggesund Paperboard representative for more information.

General properties

Printing side The surface finish of a foil or film laminated printing surface is determined by the smoothness of the baseboard, and by the amount of plastic applied. A smooth baseboard together with a high gloss chill roll and plastic results in a smooth printing surface. The surfaces are subjected to chemical modifications to achieve good ink wetting. The finished surface can be damaged by handling, friction, high stacking, fingerprints, etc. When printing on a foil or film laminated surface special inks are required. You should consult your ink supplier.

Reverse sideThe finish on the reverse side of plastic coated products is NSO (non-set-off). This means that the plastic surface has small elevated spots. This is achieved by the use of a chill roll with a special surface. The resulting point contact with the underlying sheet ensures low friction and facilitates quick drying and avoids set-off. For plastic grammages below 15 g/m², the function of the NSO finish is successively reduced. To minimise the risk of blocking in printing and converting processes, avoid plastic grammages below 15 g/m² on the reverse side of products coated on both sides. One-side plastic coated board is usually corona treated to improve the sealing characteristics and to permit gluing with waterbased adhesive. If the reverse side is plastic coated, please consult the information in the respective specification.

StorageImmediately after being manufactured, the finished paperboard is packed in a moisture-proof wrapper. The wrapper offers satisfactory protection against moisture changes, but only as long as it is left on intact. Leave the moisture-proof wrapping on until the paperboard is to be converted. Two-side plastic coated board will tend to stick together if exposed to high pressure and/or temperature, leading to friction blocking problems. If the corona treatment is damaged reduced wetting with printing inks may result. Since the corona treatment is influenced by handling and storage conditions we recommend that the material is used within six months after production.

Barrier properties

Foil and film laminates are used on paperboard to provide protection against wet or aggressive products and to provide a barrier against moisture loss and gas transfer. The construction of the package and its closures are in many cases the factors which limit the total protective function of the package.

The shelf life of the packed product depends on parameters such as: · Quality and geometry of the product · Filling level in the package · Exposed area of the product · Chemical properties of the product · Storage conditions

When selecting a suitable protective plastic barrier it is necessary to refer to previous experience with similar packing requirements and also to consider the specific barrier. Typical values for our most common plastic coatings are tested according to ASTM F-1249/ DIN 53122 (water vapour permeability) and ASTM D-3985/DIN 53380 (oxygen permeability).

Alubarrier

Product description

Paperboard with aluminium foil laminated onto the reverse side is suitable for packaging applications where sensitive products should be protected from moisture and diff gases. The aluminium lamination makes the board practically impermeable to light, moisture, flavours and gases.

A PE coating on top of the aluminium foil protects the foil from aggressive products, and makes the surface sealable. The printing side of the baseboard can be coated with PE, as with standard two-sides plastic coated board.


The aluminium foil lamination gives: · Good sealability · Excellent moisture, flavour and gas barrier from the inside · Excellent light barrier

The reverse side is normally an NSO (non-set-off) surface for reduced ink set-off tendency and improved friction.

To attain specific properties, paperboard is combined with various plastics, films, foils or other additional paperboard layers. The choice of material is determined by the desired properties. These can be barriers against moisture and grease, heat tolerance, strength or combinations of these qualities.

Iggesund Paperboard’s developers often participate in customers’ packaging development, thereby acquiring a broad overview of packaging solutions. Our developers have gained an indepth knowledge of various material combinations and ways to optimise the performance of an end product. This knowledge can help determine the best solution for the product’s journey through the distribution system from manufacturer to consumer. In addition to what is presented in the catalogue, there are products available for various lid applications, end-use areas in which pigmented polymers and unique combinations of paperboard can prove useful. Contact your local Iggesund Paperboard representative for more information.

By using paperboard as a carrier for the plastic, the amount of plastic used can be reduced to about a fifth of what would have been required for an equivalent plastic container.

General properties

Print side The surface finish of a plastic coated printing surface is determined by the smoothness of the baseboard and by the amount of plastic applied. A smooth baseboard together with a high gloss chill roll and enough plastic results in a smooth printing surface. The coated surface is subjected to chemical modifications by corona treatment to achieve good ink wetting. The finished surface can be damaged by handling, friction, high stacking, fingerprints, etc. When printing on a plastic or foil coated surface special inks are required. You should consult your ink supplier.

Reverse sideThe reverse side of plastic coated products is matt. It has a NSO (non-set-off) surface with small elevated spots. This is achieved by the use of a chill roll with a special surface. The resulting point contact with the underlying sheet ensures low friction and facilitates quick drying and avoids set-off. For plastic grammages below 15 g/m², the function of the NSO finish is successively reduced. To minimise the risk of blocking in printing and converting processes, avoid plastic grammages below 15 g/m² on the reverse side of products coated on both sides. One-side plastic coated board is usually corona treated to improve the sealing characteristics and to permit gluing with water-based adhesive.

StorageImmediately after being manufactured, the finished paperboard is packed in a moisture-proof wrapper. The wrapper offers satisfactory protection against moisture changes, but only as long as it is left on intact. Leave the moisture-proof wrapping on until where the paperboard is to be converted. Two-side plastic coated board will tend to stick together if exposed to high pressure and/or temperature, leading to friction blocking problems. If the corona treatment is damaged reduced wetting with printing inks may result. Since the corona treatment is influenced by handling and storage conditions we recommend that the material is used within six months after production.

Plastic Coatings

Barrier properties

Plastic coatings are used on paperboard to give a protection against wet or aggressive products and to provide a barrier against moisture loss and gas transfer. The construction of the package and its closures is in many cases the factors which limit for the total protective function of the package.

The shelf life of the packed product depends on parameters such as: · Quality and geometry of the product · Filling level in the package · Exposed area of the product · Chemical properties of the product · Storage conditions

When selecting a suitable protective plastic barrier it is necessary to refer to previous experience with similar packing requirements and also to consider the specific barrier. Typical values for our most common plastic coatings are tested according to ASTM F-1249/ DIN 53122 (water vapour permeability) and ASTM D-3985/ DIN 53380 (oxygen permeability).

Invercote GP + PET Coatings

Invercote GP

PET-coating

Product description

Paperboard with polyethylene terephthalate (PET) coating is suitable for packaging applications where the temperature resistance and fat barrier are important. It is amorphous at delivery and sealable.

At temperatures around 70°C it is transformed successively to a partly crystalline state with a melting point of approximately 260°C. This means that the heat sealing properties of the package will deteriorate when heated. It can be used for food products that are cooked in the pack and/or reheated in a microwave or conventional oven.

It is suitable for cooking/reheating in the tray and for lids. A black pigmented version is also available.


The PET coated paperboard can be used for applications up to 220°C, depending on the degree of fill and gives: · Extremely good temperature resistance · Good sealability · Excellent oxygen barrier from the inside · Extremely good fat barrier from the inside

The reverse side always has a glossy finish for improved surface characteristics.

Invercote GP + PET Coatings



Invercote GP + Bio Coatings

Invercote GP

BIO-coating

Product description

The bio coating is based on renewable resources and adapted for organic recovery through composting or anaerobic digestion. Combined with a selected number of Invercote grades, the material is suitable for packaging applications where biodegradability is desired. Both the baseboard and the coating conforms to the European Standard regarding compostability, EN 13432. The product also works well in existing packaging recycling systems.

Invercote Bio is particularly suitable as an alternative to PE as a barrier against grease and liquids, e.g. ice cream, cups for cold drinks and chilled food. The converting properties, such as die-cutting, heat sealing and creasing are comparable to those of PE, though its tensile strength is higher.


The Bio coating gives: · Heat sealing · Gluing · Fat barrier · Liquid water barrier from the inside · Neutral from a taint and odour perspective

The reverse side has a glossy finish for improved surface and barrier characteristics.
