Release Liner - What is a release liner?
The bottom layer in a pressure sensitive construction. The release liner carries the adhesive and face material of a pressure sensitive label. The release liner 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 release liner protects the adhesive and supports the face material during the die cutting process, printing process, and storage.
Release liners are usually made of paper, although film may be used in order to reduce the overall thickness of a sheet or roll of labels and to provide a base that is stronger and more durable - particularly during the die cutting process - although film liners are more expensive than paper liners.Go Back to Glossary
