Huamei is a leading factory specializing in PET release films, with over a decade of experience in film production.Our company's professionals have provided the following introduction to PET release film:

A PET release film (Polyethylene Terephthalate release film) is a specialized type of plastic film coated with a release agent (such as silicone) on one or both sides, allowing it to act as a protective or separation layer in industrial and manufacturing processes.

Key Features & Uses:

1. Non-Stick Surface – The silicone coating prevents adhesion, making it easy to peel off from sticky materials.

2. Heat Resistance – PET films can withstand high temperatures, making them suitable for processes like lamination, PCB (printed circuit board) production, and composite molding.

3. Chemical & Moisture Resistance – Protects sensitive materials from contamination.

4. Durability & Clarity – PET is strong, flexible, and often transparent, useful in optical and display applications.

Common Applications:

• Adhesive Tape Backing – Used as a liner for pressure-sensitive tapes.

• Composite Manufacturing – Prevents resin from sticking to molds in carbon fiber or fiberglass layup.

• PCB & Flexible Circuits – Acts as a protective layer during production.

• Labels & Stickers – Serves as a carrier film before application.

• Medical & Packaging – Used in wound dressings, medical tapes, and food packaging.

Types of PET Release Films:

• Single-Sided Release Film – Coated on one side only.

• Double-Sided Release Film – Coated on both sides for applications requiring separation from multiple layers.

• Differential Release Film – Offers different release forces on each side (e.g., easy peel on one side, stronger hold on the other).

PET release films are widely favored for their balance of performance, cost-effectiveness, and recyclability compared to other materials like PE (polyethylene) or PP (polypropylene).
