What Is a Film Release Liner?
A film release liner is a polymer-based substrate designed to protect pressure-sensitive adhesives, sealants, or tacky materials until the point of use. Compared to paper release liners, film release liners offer superior dimensional stability, moisture resistance, smoothness, and cleanliness, making them ideal for high-precision converting and automated manufacturing environments.
Among film liners, PET release liners are widely used due to their excellent flatness, strength, and thermal resistance. However, no single substrate fits every application. That’s why Fox River Associates supplies multiple film release liner options, matched precisely to each customer’s end use.
Film Release Liners from Fox River Associates
Fox River Associates supplies a comprehensive range of film release liner materials, including:
- PET Release Liners – Exceptional dimensional stability, temperature resistance, and smoothness for tight-tolerance applications
- HDPE Release Liners – Durable, cost-effective liners with good stiffness and chemical resistance
- LDPE Release Liners – Flexible liners suited for contouring and lower-stress applications
- PP Release Liners – Lightweight, strong release liners with excellent moisture resistance
