Top 5 FAQs About Film Release Liners

Used as a carrier to many types of adhesives and tacky substances, film release liners keep the adhesive or chemical clean, usable and maintain its integrity until its ready to be released from the liner for its next purpose. Film release liners are produced with a base film layer and a release layer, the construction allows the release of the adhesive material when needed.

What types of films are available for release liners?

Release liners are constructed of several base film substrates – each with its own performance characteristics. Release liners are not one-size-fits-all products. Identifying what film substrate is most appropriate for your release liner application is best determined by working with an experienced Fox River Associates representative who will work with you to understand your specific needs.

Fox River Associates offers a full breadth of film release liner substrates, including Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polyester (PET), Polypropylene (PP), and Specialty Films like Flat LDPE (no release coating) and Embossed LDPE (no release coating).

Film release liners from Fox River Associates are available coated on one side with release coating or on two sides. Two sided release coatings can be equal or differential.

When is film preferred over paper for release liners?

Film release liners and paper release liners are both widely used in all market applications from medical and industrial to tapes, composites and building and construction.

Film release liners provide a good physical barrier to release coatings, moisture, and air. Film release liners are durable, especially when exposed to environmental and processing conditions such as high temperatures, tacky chemicals and moisture.  Some films have an inherent ability to stretch, which can be a performance benefit. For release liners, films have better hygro stability than papers and will not shrink or expand when exposed to water.

Film release liners offer excellent printability, they are permeable and breathable, and they are heat resistant at warm to moderately hot temperatures and can act as an insulator.

The Fox River Associates team can help explain the features and benefits of film release liners and paper release liners to help ensure you identify and specify the appropriate release liner for your application. Use the form on this page or message us at info@foxriverassociates.com today.

What adhesives and tacky substrates are film release liners compatible with?

There are many different adhesives and tacky chemical compounds that film release liners are designed to carry. Common adhesives include acrylic, hotmelt, removable and rubber adhesives. These adhesives are found generally in medical, tape, label, and graphic arts, industrial and even specialty converting applications.

Specialized adhesives such as hydrocolloid and hydrogel adhesives are found in medical applications using film release liners. Film release liners in tape and industrial applications are also compatible with SBC. Film release liners in the aerospace & composites industries are often used to carry hot melt cyanate ester resin, hot melt epoxy resin, misc. hot melt resins and solvated resin systems. In addition to acrylic and hot melt adhesives, film release liners in the tape and building and construction industries can also be used to carry butyl.

Silicone adhesives can be used with filmic release liners that have a specialty release coating that is compatible with the silicone adhesive. Specialty fluorosilicone release liners are available from Fox River Associates for use with silicone adhesives in medical, industrial, and tape applications.

When working with your Fox River Associates representative you’ll want to talk about the adhesive and tacky chemical you’re coating along with the expected coat weight and desired release force. Our experienced team is ready to work with you. Call us today at 1-800-647-6579or message us at info@foxriverassociates.com.

What do I need to know about the release coating on film release liners?

Release coatings, often silicone coatings, are designed to provide release force that is compatible with the adhesive or tacky chemical being coated, as well as with the method of removal of the release liner. What is most critical is that your adhesive removes cleanly and easily in your operation, without any silicone migrating into the adhesive.

Silicone release liners are designed with various release forces that are targeted for intended applications. Often referred to as easy, medium, or tight release, the release force should be stable under your intended manufacturing and processing environment.

Release agents are often silicone, but not always. Silicone adhesives, for example, cannot use silicone release agents. Special fluorosilicone release agents must be used with silicone adhesives. Fox River Associates can help you identify the appropriate release liner to use with your silicone adhesives.

Are film release liners more expensive than paper release liners?

Cost should not be the primary determining factor when choosing a release liner. Although paper release liners are often used where cost effectiveness is needed, film release liners offer benefits for efficiency and performance in many operating environments. By working with an experienced release liner supplier, like Fox River Associates, you can be assured that you’re using the most appropriate release liner for your application – identified for high quality performance and efficient manufacturing processes.
