FACTS ABOUT CARTONS<br />
WHAT DOES A TYPICAL PALLET OF CARTONBOARD LOOK LIKE?<br />
<strong>Carton</strong>board is ei<strong>the</strong>r purchased in sheets or reels depending on <strong>the</strong> requirements of <strong>the</strong> printing or conversion processes.<br />
The sheet or reel dimensions depends on <strong>the</strong> requirements of <strong>the</strong> printing press <strong>and</strong> <strong>the</strong> layout of <strong>the</strong> printed copy.<br />
HOW MANY CARTONS ARE OBTAINED FROM ONE TONNE OF CARTONBOARD?<br />
This mainly depends on <strong>the</strong> size of <strong>the</strong> carton <strong>and</strong> <strong>the</strong> amount of cut off waste during production. In <strong>the</strong> early design<br />
stage carton producers fit <strong>the</strong> cartons on <strong>the</strong> sheet to reduce waste to an absolute minimum. As an approximate example,<br />
one tonne of cartonboard would make around 11,000 large cereal cartons. How many also depends on <strong>the</strong> gramma ge of <strong>the</strong><br />
cartonboard used. This is carefully chosen to secure stiffness of <strong>the</strong> finished folding box. The sheets are customised to<br />
meet <strong>the</strong> requirement of converter's design <strong>and</strong> printing press. Each sheet is optimised to minimise cut off waste during<br />
<strong>the</strong> production process.<br />
In practice one tonne would be too large or heavy to h<strong>and</strong>le as a single unit. A medium sized pallet of board would have<br />
dimensions of, for example, 720 x 1020mm <strong>and</strong> would have a height of about 1350mm, of which 150mm would be <strong>the</strong> height<br />
of <strong>the</strong> wooden platform (pallet base) on which <strong>the</strong> sheets were stacked. The number of sheets would depend on <strong>the</strong><br />
thickness of <strong>the</strong> cartonboard. The weight of cartonboard on <strong>the</strong> pallet described could weigh from around 540kg to 680kg<br />
depending on <strong>the</strong> type of cartonboard.<br />
