General information
A fundamental physical property that defines a cartonboard is the grammage (basis weight). The grammage of a cartonboard is measured according to EN ISO 536 and indicates the weight of a cartonboard per area in g/m². The determination of the grammage is carried out by gravimetric methods. The total mass is the sum of fibre materials, coating, fillers, additives and water.
Additional details – practical relevance
The basis weight consists of the combined weight of the uncoated cartonboard and the coating. The amount of fibres has a significant relevance for the strength and stiffness of the cartonboard.
