PET Film Supply Company is a China Release Coated PET Film manufacturer producing polyester release liner film for labels, industrial tapes, die-cut parts, protective film converting, and electronic materials. Release Coated PET Film is selected when clean release, stable unwind, strong tensile performance, and reliable dimensional stability are required. It is commonly supplied in single-side or double-side coated structures, with silicone or non-silicone systems, custom release force, and multiple thickness options for industrial converting lines.

Product Overview

Release Coated PET Film is a polyester-based liner with a controlled release surface that allows adhesive products to separate smoothly during coating, laminating, slitting, die-cutting, and final application. It is widely used in precision converting because PET combines flatness, heat resistance, thickness consistency, and strong web handling. These properties help reduce curl, improve running stability, and support cleaner processing in applications where liner performance affects yield, registration, and finished roll quality. Non-silicone constructions are also available for processes that need reduced silicone transfer risk.

Applications

  • Pressure-sensitive labelstock
  • Industrial adhesive tapes
  • Foam tape and transfer tape liners
  • Die-cut carriers
  • Protective film processing
  • Electronic component assembly
  • Medical adhesive constructions
  • Laminating and coating operations

Benefits

  • Stable release for smoother converting
  • Strong tensile performance for web handling
  • Better flatness for coating and die-cutting
  • Good heat resistance for demanding processes
  • Custom release levels for different adhesives
  • Available in single-side and double-side versions
  • Optional anti-static or specialty surfaces
  • Consistent roll quality for industrial use

What Release Force Should You Choose?

Release force should be selected according to adhesive tack, unwind speed, and the way the finished product is processed. A lighter release is often preferred when fast liner removal is important, while a medium or tighter release is more suitable for aggressive adhesives or for parts that must remain in position during converting. In practical production, the liner should match the adhesive system and processing conditions instead of being chosen by thickness alone. That approach helps improve peel stability, handling efficiency, and finished product consistency.

Common Specifications

This material is usually selected by a combination of thickness, release level, coating side, color, width, roll length, and the adhesive system that will contact the liner. Each point affects unwind stability, die-cut accuracy, waste stripping, and roll consistency on the production line. For that reason, PET Film Supply Company presents this film as a specification-matched industrial liner rather than a generic sheet material. A well-matched structure can help reduce running problems and support more repeatable converting results across different product programs.

Surface and Construction Options

Release Coated PET Film is available in more than one standard structure. Single-side coated film is often used when only one release surface is needed, while double-side coated film is suitable for more complex laminating or converting conditions. Clear and colored films are both common, and anti-static or specialty surfaces can be used for electronics and other precision adhesive applications. The most useful way to specify the film is to match the structure to the process window, adhesive behavior, and final product requirement.

How Is PET Different From Paper Release Liners?

PET is often selected when better dimensional stability, stronger mechanical strength, improved flatness, and lower sensitivity to moisture-related distortion are needed. Polyester liners help support steadier web control under tension and cleaner handling during precision converting. Paper liners may still fit cost-sensitive uses, but PET is often the better option when process consistency, tighter tolerances, and cleaner release performance matter more than the lowest initial liner cost.

FAQ

What is Release Coated PET Film mainly used for?

It is mainly used as a release liner or carrier film for labels, industrial tapes, die-cut parts, protective films, and electronic materials.

Is single-side or double-side coating available?

Yes. Both single-side and double-side coated PET release film are common options in this product category.

Can non-silicone Release Coated PET Film be supplied?

Yes. Non-silicone versions are available for applications that need controlled release without silicone transfer.

What should be confirmed before sampling?

Thickness, release force, coating side, color, width, roll length, adhesive type, and end-use process should be confirmed first so the film can be matched correctly.
