Corrugated Cardboard Spec Sheet

Overview

• The Outer Liner generally high quality Kraft
• The Flute - this separates the inner and outer liner and gives the board its strength
• The Inner Liner important for strength but not so important visually
• Double wall board has an extra central liner and 2 sets fluting.
• Test and Chip liners are made from recycled fibres.
• TL2 is made entirely from recycled fibres but offers a better visual performance and improved printability over ordinary test.
• Kraft was originally made from 100% virgin wood pulp, but now contains a proportion of waste based material.
• White Top Kraft is made by bleaching or coating the surface fibres
• Mottled Kraft is a surface layer of bleached fibres randomly applied resulting in a mottled appearance

Fluting

• The flute is produced with recycled paper with added chemicals and starch to give good sheet strength and excellent fluteability
• The weight of standard fluting is 105-112 gsm
• Standard central liners in double wall material are 100 - 110chip

Alternative flutings available are as follows:

• 127 , 150 , 175 , 200 gsm

Calliper Thickness

• B Flute 3 mm
• C Flute 5mm
• BC Flute 8mm

Stack quantities per pallet of unfinished sheet.

• B = 350 sheets
• C = 250 sheets
• BC = 160 sheets

Note! Small sheet sizes will be placed more than one up on a pallet

Stack quantities per pallet finished cartons

• B = 175
• C = 125
• BC = 80

Note! Small carton sizes will be placed more than one up on a pallet

Testing & Lab Facilities Available To Customers

• Basis Weight – Grammage of paper per m 2
• Ring Crush Test – Relates to box compression strength, measured in Newton’s
• Burst Strength – Gives an indication of the containability of the paper.
• Calliper – Measures the thickness of the paper usually in Microns.
• Cobb Test – Measures the water resistance of the paper.
• Moisture Content – Measures the % of water in the paper (normally 6-10%)
• Combined Grammages – Weight of board per m 2
• Edge Crush Test – Relates to the box compression
• Flat Crush Test – Gives an indication of the cushioning characteristic of the board
