What is paper bulk?

Описание к видео What is paper bulk?

Bulk is the reverse of density. It describes the volume of one gram of a substance. This measurement is really useful when comparing printing papers. A paper with high bulk is thick, but weighs less since it contains more air. Since you buy paper in tonnes, you get more printing surface per tonne than if you buy a paper with lower bulk. A fresh fibre high bulk paper also has better opacity and stiffness in the sheet. Letting you use a lower grammage without compromising the look and feel of your printed matter.
