Release Liner Engineering
Film and Paper Release Liners Built for Your Application
Today's coating, converting, and manufacturing environments are more sophisticated than ever. Specialized raw materials, precision manufacturing operations, and demanding finishing processes combine to produce highly engineered finished products used across a wide range of industries and applications. Behind many of these products is a release liner, and that release liner is rarely a commodity item. It is a highly engineered, application-specific component that directly affects how well your product performs, converts, and reaches your customer in the condition it needs to be in.
Fox River Associates takes seriously our role in the success of your finished product. We supply one of the broadest ranges of paper release liner and film release liner options available to converters across North America, and we approach every inquiry with the understanding that a release liner is not a "one-size-fits-all" product. The highest performing release liner is the one engineered for your process, your equipment, and your end use, not simply the one that happens to be in stock somewhere.
What Determines the Most Appropriate Release Liner for Your Application?
The optimum release liner is determined by processing conditions and end-use requirements working together. Several variables factor into proper release liner selection: the physical properties of the substrate, process and storage temperatures, die-cutting and slitting requirements, adhesive type and coating method, line speed, and the environmental conditions present at your converting or coating location. Each of these variables affects how your product performs during manufacturing and how it looks and functions once it reaches your customer.
This is exactly why Fox River Associates works directly with customers rather than simply filling orders. Our experienced team asks the right questions up front, about your adhesive system, your converting equipment, your temperature range, your release value requirements, and your end-use environment, so that the release liner we recommend is matched to your actual application, not a generic specification. In many cases, this collaborative process results in us recommending more than one release liner option, allowing you to trial and compare performance before committing to a single specification. That is what a true release liner partner does, and it's the approach we've refined over more than 35 years of working exclusively in this space.
If you're evaluating release liner options for a new or existing application, call Fox River Associates at 1-800-647-6579, or fill out the form on this page. One of our associates will walk through your specifications with you and help identify the film or paper release liner best suited to your needs.
Film and Paper Release Liners Designed for Your Needs
Every release liner market has its own specialized requirements and processing environment, and our team has built deep familiarity with the core industries we serve. Because we understand the individualized specifications each market demands, our team can move quickly from initial conversation to a shortlist of appropriate release liner options, saving you the time and cost of trial-and-error sourcing.
Our film release liner offering includes PET, PP, LDPE, and HDPE films, along with silicone-coated and non-silicone-coated embossed film release liners and specialty coextruded film constructions. Our paper release liner offering includes Glassine, SCK, PCK, CCK, and additional specialty paper substrates. Release liners are available coated one side, two sides, or with differential two-side coatings, and select substrates are available with specialty coatings or no coating at all, depending on your application. This breadth means that whether your process calls for the dimensional stability of a film release liner or the cost efficiency and printability of a paper release liner, Fox River Associates has a release liner engineered to fit.
Beyond substrate selection, our team brings advanced working knowledge of release coatings, adhesives, resins, chemical coatings, and end-use processing conditions. This knowledge is what allows us to serve as a true technical partner, not just a supplier, throughout your design, specification, and trial process for both film and paper differential release liners.

Which Industries Rely on Fox River Associates for Release Liners?
Medical Release Liners: Medical markets demand stringent specifications and work with a wide diversity of adhesive systems. Fox River Associates understands the manufacturing and end-use realities of medical applications, including clean room environments and sterilization processes, and our team can help you quickly identify the release liner suited to your specific medical device or wound care application.
Industrial Release Liners: Industrial applications often expose release liners to extreme temperatures and demanding handling conditions, requiring a liner that is simultaneously flexible, durable, and high in tensile strength. Our full range of film release liners and paper release liners has been proven in these demanding industrial settings.
Composites Release Liners: Release liners used in prepreg manufacturing for composite products face extreme temperature swings, sometimes as high as 300°F and as low as 0°F, and must maintain dimensional stability across that entire range. Fox River Associates is committed to serving this market, and our team is well versed in identifying release liners that hold up under these conditions.
Tape and Graphic Arts Release Liners: These markets depend on consistent surface characteristics, caliper, smoothness, and strength to support high-speed coating, precision die-cutting, and sophisticated converting operations. Our team understands the performance characteristics these applications require and works with you to identify the release liner that keeps your line running smoothly.
Why Should North American Converters Choose Fox River Associates as Their Release Liner Supplier?
Release liners are the only thing we do. For more than 35 years, Fox River Associates has focused exclusively on release liners. That singular focus has allowed us to build deep, specialized expertise in substrates, coatings, adhesives, and converting requirements that a generalist supplier simply cannot match. It has also made us a stable, dependable partner: a company whose entire business depends on getting release liners right for our customers, year after year.
That focus shows up in how we serve you. Fox River Associates offers the shortest lead times in the release liner industry, backed by a service program built specifically around converter needs. We maintain stocked inventory so that when you need release liner in large roll quantities to keep a production run moving, it's available, we never want your operation to be at risk because release liner wasn't on hand when you needed it. At the same time, we offer small minimum order quantities, which makes us an ideal partner for startups, emerging applications, and small to medium-sized converters who need flexibility rather than being locked into large-volume commitments.
Fox River Associates is certified ISO 9001:2015. For converters, this certification matters because it means our quality management systems, documentation, and process controls are independently verified and consistently maintained, giving you confidence that the release liner you receive today will perform the same way as the release liner you receive next year.
We primarily serve converters located in the United States, Canada, and Mexico, and our service programs, inventory, and logistics are built around supporting this North American manufacturing base.
