The thickness of the paper is measured in grams per square meter (g/ m2 ). The higher the weight
number of the paper, the thicker it is. So our cards vary in weight from 263g to 330g depending on the
type of paper. When we talk about EarthPact® paper, that is an ecological paper, we talk about a
grammage of 263g and when we talk about Propalcote or Opalina we can talk about a grammage
between 300 and 330 grams per square meter.
