Cartonboard Production

Cartonboard is made from cellulose fibres from trees. Worldwide, about 50% of paper and board is made from cellulose fibres that come directly from trees, and 50% is made from cellulose fibres from waste paper and board.

Cartonboard is a multilayer material which usually consists of 3 or more fibre layers.  The various layers are combined during a wet pulp phase of the manufacturing process before the cartonboard is pressed by large rollers and passed over steam heated cylinders to evaporate water.  At the end of these processes, the fibre layers are bonded together.  The cartonboard is dried and rolled onto huge spools.  As a final process the cartonboard spool is cut into customized sheets matching the exact requirements of the carton converter’s and brand owner’s design.  Each cartonboard mill produces dozens of different customized sheet sizes every day.
