PET Film

Product Overview

NIPPA's release films are manufactured in a clean environment, offering a wide range of product lines that can be customized according to your needs. To prevent defects, especially for overseas markets, our products are equipped with an anti-static layer.

Types of Release Agents for PET Films

Silicone-Based Release Agents: Suitable for acrylic and rubber adhesives
Fluorine-Based (Fluorosilicone) Release Agents: Suitable for silicone adhesives
Non-Silicone Release Agents: Suitable for projects requiring no siloxane or for low-viscosity tape adhesive protection
※Dual-side different release support (e.g.) A-side: Easy Release / B-side: Tight Release

Static electricity can damage the release coating. Using ASI products with anti-static functions can reduce this risk. ※AS=Anti-Static
