What is PET Release Film?

PET (Polyethylene Terephthalate) release film is a high-performance material widely used as a protective layer in composite manufacturing, PCB production, and adhesive applications. This biaxially-oriented polyester film features a silicone or non-silicone release coating that allows easy separation from sticky surfaces while maintaining excellent dimensional stability.

Key Advantages: 

Temperature Resistance: Withstands -40°C to 150°C (up to 200°C for short periods)

Chemical Stability: Resists solvents, oils, and most acids/alkalis

Uniform Thickness: Precision-controlled from 12μm to 250μm

Optical Clarity: Ideal for visual inspection during lamination processes

Environmental Benefits: 100% recyclable with lower carbon footprint than alternatives

Primary Applications:

Composite Manufacturing: Essential for aerospace (carbon fiber layup), wind turbine blades, and automotive parts

Electronic Components: Used in flexible PCB production and display module assembly

Medical Products: Sterilizable release layer for adhesive dressings and surgical tapes

Industrial Tapes: Carrier film for double-sided tapes and labels
