PET release film

What is PET release film? It uses BOPET film as the base material, with a layer of silicone oil coated on the surface to reduce adhesion and achieve a release effect. Available in single-sided and double-sided release versions; standard thicknesses range from 0.012mm to 0.1mm. Release force can be customized to client specifications, and the material can be slit into rolls or cut into sheets.

PET Release Film – JL60R

PET Release Film is a silicone-coated polyester film made with BOPET as the base material. The silicone release coating provides a controlled release surface, helping separate adhesive materials during lamination, converting, die-cutting, and other industrial processes.

Jinlu supplies PET release film in transparent roll formats, with single-sided and double-sided silicone coating options. Different thicknesses, widths, and release force requirements can be discussed according to the adhesive system and final application. Slitting and sheet cutting services are also available.

Key Features of PET Release Film

1. Silicone-Coated Release Surface

The silicone coating creates a release surface that reduces adhesion between the film and contacting adhesive materials. Release performance should be matched to the adhesive formulation, peeling requirements, and converting process.

2. Single-Sided and Double-Sided Options

Single-sided PET release film has a silicone release coating on one surface. Double-sided PET release film has release coatings on both surfaces. The appropriate structure depends on how many adhesive interfaces require release.

For a more detailed explanation of these two structures, see our guide to Single-Sided vs Double-Sided Release Film.

3. Multiple Thickness Options

PET release film is available in thicknesses from 12 μm to 100 μm. Thinner films can suit lightweight adhesive constructions, while thicker films provide more body and support during handling, rewinding, and die-cutting.

4. Custom Release Requirements

Release force is an important selection factor. The required release level depends on the adhesive type, coating structure, contact time, temperature, and peeling conditions. Buyers should evaluate the film together with their actual adhesive materials before mass production.

5. Roll Slitting and Sheet Cutting

Jinlu can supply PET release film in roll form and arrange custom slitting or sheet cutting according to the required dimensions. Standard and customized widths can be discussed based on the customer’s equipment and production requirements.

Applications of PET Release Film

  • Adhesive Labels: Used as a release liner to protect pressure-sensitive adhesive layers before application.
  • Double-Sided Adhesive Tape: Used in adhesive constructions requiring controlled separation during unwinding and application.
  • Precision Die-Cutting: Provides a supporting release liner during adhesive converting and cutting processes.
  • Protective Film: Used in selected protective material constructions where a controlled release surface is required.
  • Packaging and Lamination: Used in compatible converting processes involving adhesive layers and release surfaces.
  • Industrial Insulation: Can be considered for suitable industrial constructions according to the actual material and process requirements.

How to Select the Right PET Release Film

Before selecting a PET release film, buyers should confirm the following information:

  • Required film thickness and width.
  • Single-sided or double-sided silicone coating.
  • Target release force and test method.
  • Adhesive type and intended contact surface.
  • Roll length, core size, and winding requirements.
  • Final application and processing conditions.

Providing these details helps identify a suitable film structure and reduce compatibility issues during production. Release performance should always be checked with the actual adhesive and operating conditions.
