PET Release Liner (General)

Product Description

PET release liner is a high-performance film made from polyethylene terephthalate (PET), coated with silicone or other release agents to reduce surface adhesion and provide controlled release properties. Available in single-sided or double-sided formats, and customizable in release strength (light, medium, or heavy), PET release liners offer exceptional mechanical strength, thermal stability, and chemical resistance. Widely used in electronics, adhesives, printing, medical, and packaging industries, they ensure clean separation in precision processing applications, even under demanding environmental conditions.

As a professional supplier of plastics and related services, we at Alfa Chemistry offer a comprehensive range of specialty materials, including advanced PET release liners, engineered to meet the demanding requirements of modern manufacturing and processing industries.
