Backing Sheet - What is a backing sheet?
Definition of BACKING SHEET:
The bottom layer in a pressure sensitive construction. The backing sheet carries the adhesive and face material of a pressure sensitive label. The backing sheet always has a release coating that prevents the adhesive from sticking permanently to the backing, which allows the face material and adhesive to be removed together when a label is being applied to a substrate. The backing sheet protects the adhesive and supports the face material during the die cutting process, storage, and the printing process.
Backing sheets are usually made of paper, although film may be used in order to reduce the overall thickness of a sheet of labels and to provide a base that is stronger and more durable - which is particularly important during the die cutting process - than paper. However, a film backing is more expensive than a paper backing.Go Back to Glossary
