Paperboard

Paperboard is (like paper) a 'vegetable-fibre web' formed from a water suspension. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.25 mm or 10 points) than paper. According to ISO standards, paperboard is a paper with a basis weight (grammage) above 224 g/m², but there are exceptions.^[1] Paperboard can be single or multi-ply. Paperboard used for the manufacture of folding cartons and rigid set-up boxes is often called boxboard. Paperboards used for the manufacture of corrugated fiberboard are called containerboard. It can be easily cut and formed, is lightweight, and is strong used in packaging. Another enduse would be graphic printing, such as book and magazine covers or postcards. Sometimes it is referred to as cardboard, which is a generic, lay term used to refer to any heavy paper pulp based board.
