Liner - What is a liner?
The bottom layer in a pressure sensitive construction. The liner carries the adhesive and face material of a pressure sensitive label. The 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 liner protects the adhesive and supports the face material during the die cutting process, storage, and the printing process.
Liners are usually made of paper, although films 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 - particularly during the die cutting process - than paper (although film liners are more expensive than paper liners).Go Back to Glossary
