Two of the most basic physical properties that defi ne a paperboard
are grammage and thickness. These properties
tell us how much fibres and coating that is used for one
square meter of board, and what thickness that results
in. Based on grammage and thickness the density, or the
bulk which is the density inverted, can be calculated and
is often used to indicate whether a paperboard has a high
or a low thickness at a given grammage. E.g. low density =
high bulk = high thickness
