Release liner

A release liner or release paper, also called a backing liner, is a paper or plastic-based film sheet (usually applied during the manufacturing process) used to prevent a sticky surface from prematurely adhering.

Globally there are between 400 and 500 companies involved in making or dealing with release liner products on an industrial scale.

They provide unique solutions to their customers, based on a wide variety of substrates and an endless combination of release agents with specialized properties.

An in-house producer makes the release liner and uses it internally to manufacture the final product.

In-house producers are typically focused on a very narrow range of products e.g. labels or tapes.
