Fox River Associates Film Release Liner Offering

Film release liners are manufactured from a variety of polymers, each chosen for its unique properties tailored to specific applications. Fox River Associates offers a full range of filmic release liners to serve key market applications.

Polyester (PET) Release Liners

PET film release liners deliver exceptional dimensional stability, even under thermal and mechanical stress. These filmic release liners have high tensile strength and resistance to moisture. PET film release liners are suitable for high-performance applications.

PET is often favored over other films for release liners in industries like medical, electronics and composites where precision, heat resistance, and durability are paramount. PET release liners are also widely used in high-performance tapes, graphics, and label applications.

Polyethylene (PE) Release Liners

Film release liners constructed of PE are available with low-density polyethylene (LDPE) and high-density polyethylene (HDPE). PE release liners are flexible and conformable, especially LDPE. These release liners are lightweight and economical. HDPE offers good tensile strength and rigidity.

PE films are often used in protective surface applications, building materials, and low-performance tape release liners. They are suitable for scenarios where cost and flexibility are priorities, though their dimensional stability may limit use in precision applications.

Polypropylene (PP) Release Liners

PP film release liners deliver good moisture resistance and moderate dimensional stability. These release liners offer good resistance to chemicals, making them ideal for industrial use. Release liners constructed of PE offer lower thermal resistance compared to PET.

PP film release liners are commonly used in pressure-sensitive graphic and label applications, and industrial tapes. They balance cost-effectiveness with sufficient performance for many medium-demand applications.

Fox River Associates offers a full line of filmic release liners include LDPE, HDPE, PP and PET based release liners. Additionally, specialty coextruded films are available for suitable technical applications.
