Anti-adhesive material which covers the adhesive on a double sided tape and prevents the adhesive from sticking to itself. The liner is used as a protection aid during handling, processing and storage. Most commonly used liner types are:

• Paper liners (e.g. glassine paper, PE-coated paper, clay-coated paper)
• Film liners (e.g. PP, PET, PE)

Silicone is used as a release system to avoid adhesion between liner material and adhesive.
