Density - What is density?
A measure of the weight of paper (and other materials) defined as the mass per unit area. Paper density is a form of area density; where traditional density measures the mass per volume of an object, paper density is calculated using the surface area of a material, usually when that material has been produced or cut to a standard size. Paper density is commonly expressed in grammage, which measures density as grams per square metre.
In labelling, it is important to know the weight of the materials used to make label products and the overall weight of the finished label product as heavier sheets may not feed correctly through some printers.Go Back to Glossary
