Cardboard is a flat packaging material consisting of paper stock and generally being of high-quality stock composition (e.g. white mechanical pulp board). Its basis weight is 250 - 500 g/m2. If cardboard has a basis weight of between 150 and 250 g/m2, it is described as light, while cardboard with a basis weight of 500 - 600 g/m2 is described as heavy.
Cardboard may either be single ply or consist of several paper webs couched together mechanically or stuck (laminated) together.
Boxboard (carton board) is used to make the blanks from which cartons and the like are made.
