Release Film: PET and Polyester Film Liner Guide
Release film is a silicone-coated plastic film — typically PET — that carries adhesive products where paper liners fail: high tension, high heat, or where transparency matters.

FAQ
Frequently Asked Questions
Film vs paper liner — when does film win?
High-tension winding, high process heat, precision die-cutting, or where transparency/dimensional stability matters. Paper wins on cost for standard labels.
What thickness should I choose?
Application-driven — see our PET film thickness guide for the 12-100μm map by application.
Is anti-static available?
Yes — anti-static treatment for electronics die-cutting where ESD matters.
