Introduction
A release liner is a paper or film sheet used to carry and protect pressure-sensitive adhesives until they are ready to be applied. Coated with a non-stick material like silicone, release liners ensure that adhesives, labels, tapes, or sealants don’t stick prematurely. They are essential in the adhesive tape, medical, graphic, and label industries.
