Opacity

Opacity is a measurement of the capacity of cartonboard to obscure what lies behind it, and is expressed as a percentage. A high percentage corresponds to a cartonboard sheet with low transparency (high opacity). A cartonboard sheet with 100% opacity is completely opaque. The degree of opacity depends on how well the light is scattered and absorbed by the cartonboard. High opacity is important when printing is done on both sides of the cartonboard sheet.
