One of
the two subdivisions of paper. The distinction is not great, but
paperboard is heavier in basis weight, thicker, and more rigid than
paper. All sheets 12 points (0.012 inch) or more in thickness are
classified as paperboard. There are exceptions. For example, blotting
papers, felts, and drawing paper in excess of 12 points are classified
as paper, while corrugating medium, chipboard, and linerboard less
than 12 points are classified as paperboard |
