PAPER & CARD
1 HOW IS IT MADE
1.1 Step 1: A tree is cut down and the trunk is fed into a chipping machine where it is cut into very small pieces
1.2 Step 2:The small pieces or wood chips are then boiled to form a thick wood pulp
1.3 Step 3: Chemicals such as starch and are added. The pulp is poured over a filter and the water escapes leaving the CELLULOSE fibres behind. This forms the paper.
