White Lined Chip Board
• Recycled Fibre - based grades
– White Lined Chip Board
• Multi layer boards consisting of 60 to 100 % of
recycled fibre
• Top layer produced either with high grade white
preprint waste paper or bleached chemical pulp.
• The middle layer and the back layer are made from
waste paper
• The basis weight ranges from 200 to 600 GSM
White Lined Chip Board
• Surface Brightness is 80 to 85 % ISO
• Coating grammages range from 0 to 25gsm.
• Extremely good smoothness of less than 2 Microns
PPS possible
• Hunter Gloss more than 35 %
• Cost effective substrate for gravure and offset
printing process
• Used extensively in developing world, in developed
countries use confined to non food sectors
White Lined Chip Board
Uncoated recycled board
– made of 20% virgin fibre on top or 100 % waste paper
without any coating.
– Generally laminated with other boards/ papers and
basis weight of final boards will be over 1000 GSM
– Solid packaging boards for set up boxes and other
packaging applications
– As packing dividers in corrugated boxes, luggage
manufacturing, book binding etc.
Virgin fibre-based Board
Solid bleached board
– produced entirely of bleached chemical pulp.
– The number of solid homogeneous fibre layers varies
from two to four
– Both long and short fibre are used
– surface is double coated and back is either uncoated or
lightly coated.
– The surface brightness is 90 % ISO
– top surface roughness is less than 1.2 microns PPS
– Hunter Gloss of top surface more than 75 %
Virgin fibre-based Board
Solid bleached board
– Available in 200 to 600 GSM
– Suitable for all types of Printing Process
– Considered as premium grades for packaging and
graphical purposes
– Suitable for packing aroma and flavor sensitive
products
– In general SBS are superior when purity good
appearance and runnability of the packaging material
are required.
Virgin fibre-based Board
Folding box board (FBB)
– Folding box board consists of three layers
– The top layer is of bleached chemical pulp.
– The middle layer consist of mechanical pulps: stone
ground wood pulp, pressurised ground wood ,
thermomechanical pulp or chemi thermo mechanical
pulp. This layer gives stiffness and bulk.
– The back of FBB is either manilla or white in colour
Virgin fibre-based Board
Folding box board (FBB)
– The top is coated with two layer of coating and coat
weight is in the range of 22 - 25 GSM
– A good substitute for SBS in applications where
runnability and a virgin fibre base are required
– Visual properties slightly inferior to SBS
– Suitable for all printing process- infact the most
converter friendly board
– The basis weight ranges from 200 to 450
– Ideal for Food packaging, cigarettes cosmetics,
pharmaceuticals and graphical applications.
PAPER BOARDS - Different Types
Coated unbleached kraftboard (CUK)
– made from unbleached sulphate pulp (245 - 520 GSM)
with a coating of 22- 25 g/sq..m
– The top layer under the coating may consist of bleached
chemical pulp.
– Also some recycled fibre can be used to replace part of
the unbleached sulphate pulp
PAPER BOARDS - Different Types
Coated unbleached kraftboard (CUK)
– Has very strength properties
– Used as a lower cost alternative to SBS board
– Mainly used as a beverage carrier board for both glass
bottles and cans and also in folding cartons.
– Generally suitable for all printing process.
PAPER BOARDS - Different Types
Cast coated boards and papers
-The base board can be uncoated SBS, FBB or recycled
boards
- The roughness is less than 1 microns PPS and hunter
gloss is more than 90 %
- suitable for premium packaging of cosmetics, liquor
pharmaceuticals, greeting cards, labels and others
– generally available in 220 - 450 GSM
– cast coated papers in 85/90 gsm used extensively for
labels with higher grammage papers popular in greeting
cards
PAPER BOARDS - Different Types
Liquid packaging board
– Base board is either coated or uncoated SBS, CUK or
FBB with CTMP in middle layers
– These boards are laminated with aluminium foil and
special plastic barriers.
– Requires special properties like edge wick with lactic
acid and Hydrogen peroxide and stretch.
– Mainly used for packing milk, juice and other liquids
– generally available in the range of 170 - 340 GSM
PAPER BOARDS - Different Types
Cup stock board
– Base board is normally uncoated SBS
– These boards are laminated with PE for soft drinks and
hot beverages
– generally available in the range of 170 - 340 GSM
