PET Release Film in Electronics and Medical Industry: Versatile Applications

Introduction to PET Release Printed Films

Definition and Basic Properties

PET Release Printed Films are polyethylene terephthalate (PET) films printed with functional patterns and coated with a release layer, typically silicone. These films offer excellent dimensional stability, chemical resistance, and consistent release performance. In industrial applications, they act as liners or protective layers that separate adhesives or prevent contamination during processing. Their versatility makes them indispensable in electronics and medical applications where precision, reliability, and material integrity are crucial.

• High tensile strength and dimensional stability.
• Low surface energy for consistent adhesive release.
• Resistance to chemical and thermal stress.
• Customizable surface finishes and printed patterns.
