Kraftpak in brief

Kraftpak Fibres

Pine3-5mm

Hardwood1.5mm

Strategic, controlled mix of hardwood and softwood

Kraftpak Composition

Short Hardwood FibresOne minute Cobb, 30 g/m2

Long pine fibers One minute Cobb, 30 g/m2

Uncoated, pure, clean kraft fibers. Certified compostable (EN 13432)

Kraftpak is internally sized – Low Cobb Values

Grammage to Stiffness Ratio

Kraftpak boasts a superior grammage to stiffness ratio than other GC/GD cartonboard grades 25% reduction in packaging weight can typically

be achieved when switching to Kraftpak Resulting in more Cartons per tonne

Outstanding moisture resistance and wet durability make Kraftpak the perfect choice for many challenging packaging applications

Natural Appearance A natural, non-bleached, brown appearance. Kraftpak’s fibres are uniform and consistent, but

not bleached, stained or coated Natural variation in shade is negligible as per C Lab

Kraftpak manufactured twice every 5 weeks 7-8 week delivery from receipt of order Mill located at Quay – No inland haulage delays! Thirty year history of excellent performance and

consistent customer supply Committed to the continued growth of Kraftpak

to meet increasing demand in the marketplace Increases in Kraftpak supply will be achieved

by reducing Kraft liner supply

Supply Chain

Charleston mill boasts long history of consistent reliability

Demonstrated by their 50,000mt/parelationship with a major U.S. retail brand of beverage carriers for 20 years.

Security of Supply

Sustainability

High yield pulping and low density papermaking process

COGEN power is used, 72% of mill fuel from renewable sources. All residues from waste treatment are used as biofuels

Cradle-to-gate life cycle assessment conducted by PE International finished in 2011.

Net result of Biogenic carbon storage, from uptake of CO2

in growing forest and emission from operations, results in a net carbon storage available at the Mill gate

Responsible Packaging

Kraftpak’s 100% renewable fibres are a valuable resource for Recyclers

…and are 100% recyclable where facilities exist

Should Kraftpak end up in landfill, Kraftpak is certified biodegradable and compostable (ISEGA, EN13432)

Kraftpak – Typical Markets

Food Hygiene Kraftpak meets ISEGA requirements for direct food

contact Beverage bottle carriers and baskets Beverage can carriers Frozen meats and pies Carry out takeaway trays Bakery items Fast food drink carriers Frozen biscuits Novelty ice cream packaging High performance filter frames

Kraftpak has proven, demonstrated success in all of the above environments

ExamplesWet Applications

ExamplesDry Applications

Printing - Flexo

Anilox rolls should have cell volume adequate for delivering inks and coatings to kraft board 200 lines/inch (80 lines/cm) are commonly used

Printing is possible on softwood side, but frequent wash-ups to be expected

Softer plates and cushions may be beneficial for improved surface contact

Printing - Litho

Will generally require more impression pressure than other carton grades

Compressible blankets recommended for offset Impression cylinder pressure should also be

adjusted as necessary to avoid mottle Ink film thickness of 0.5mls may be needed for

adequate ink cover Gap setting of .002” to .004” below nominal is a

good starting point

Printing – Litho

Ink tack levels in the 8-12 range (800rpm) are recommended

UV curing can provide ability to print white base patterns as needed on a single pass

Textured grippers may help with consistent sheet transfer

On litho presses, it is strongly recommended to feed kraftpak sheets in the CD direction

Cutting and Scoring

Excellent Converting Efficiencies Cutting, Scoring, Folding,

Gluing

Resulting in... Fewer rejects Increased speeds Less downtime Increased handling rates

Scoring

High strength to weight promotes excellent performance in scoring and embossing

Low density means Kraftpak is more compressible than other cartonboards

Scorelines will need to be deeper to avoid springback

Slightly higher impression pressure may be required to achieve adequate scorelines

Cutting

Cutting is similar to CUK, but significantly different to that of SBS and recycled grades

Knives need to be sharp

Fewer and smaller nicks are needed for perforation due to Kraftpak’s high fibre strength

Cutting parameters should be chosen to overcome the strong, compressible nature of Kraftpak

Scoring Parameters

Recommended initial scoring parameters (grain and cross-grain) are below. Note, these are only initial guidelines.

Rule Width 2pt rule for .013-.018 caliper Kraftpak 3pt rule for .020-.030 caliper Kraftpak

Channel Width Twice board caliper plus the rule width

Rule Penetration Target 0.006” penetration beyond top of channel
