Film Release Liners: Substrates, Properties & Applications
A film release liner uses a polymeric film as its base substrate, coated with silicone on one or both sides to provide controlled, non-stick release. Film release liners offer dimensional stability, moisture resistance, and smooth, consistent surfaces that paper-based release liners cannot always achieve — making them the preferred choice for precision applications in medical, electronics, graphic, and industrial markets.
Fox River Associates carries a comprehensive range of film release liner substrates to serve the full breadth of converter requirements in North America. Each substrate offers a distinct combination of mechanical, thermal, and chemical properties that must be matched carefully to the intended application.
Film Release Liner Substrates Available from Fox River Associates
Polyester (PET) Release Liner The workhorse film release liner substrate. PET offers excellent tensile strength, dimensional stability, temperature resistance, and surface smoothness. Available in a range of gauges from ultra-thin to heavier constructions, polyester release liners serve the widest variety of converting applications among all film substrates.
Polypropylene (PP) Release Liner A cost-effective film release liner option offering good moisture resistance and chemical resistance. PP release liners are common in pressure-sensitive label, tape, and packaging applications where a balance of economy and performance is required.
Polyethylene (PE) Release Liner Flexible, conformable, and chemically resistant, PE release liners are widely used in medical wound care, hygiene, and flexible packaging where conformability and gentle release are essential properties.
High-Density Polyethylene (HDPE) Release Liner HDPE offers greater stiffness and barrier properties than standard PE, making it suitable for demanding medical and industrial applications that require more robust release liner performance without moving to a rigid film substrate.
Biaxially Oriented Polypropylene (BOPP) Release Liner Oriented PP delivers improved clarity, stiffness, and surface quality compared to cast PP. BOPP release liners are used in graphic arts, labels, and specialty tapes where a high surface smoothness is important for adhesive performance or print quality.
Cast Polypropylene (CPP) Release Liner Cast PP release liners offer good flexibility and broad chemical compatibility. They are used in food packaging, flexible adhesives, and specialty industrial converting applications requiring a softer, more conformable film release liner.
What Are Film Release Liners Used For?

Paper Release Liners: Substrates, Properties & Applications
A paper release liner uses a paper-based substrate — treated, coated, or clay-coated — as the carrier for a silicone release coat. Paper release liners are among the most widely used release liner formats in North America, valued for their printability, recyclability, rigidity, and cost-effectiveness across a vast array of converting and end-use applications. Fox River Associates stocks a comprehensive selection of paper release liner substrates to serve converter needs at every volume level.
Paper Release Liner Substrates Available from Fox River Associates
Glassine Release Liner A supercalendered, highly transparent paper with excellent silicone holdout and a smooth, consistent surface. Glassine paper release liners are the industry standard for pressure-sensitive label stock across countless North American markets, valued for their reliable release performance and broad converter compatibility.
SCK (Super Calendered Kraft) Release Liner A cost-efficient paper release liner substrate with good surface quality and broad availability. SCK is widely used in label face stock constructions, general-purpose tapes, and commodity pressure-sensitive adhesive applications where economy and performance must be balanced.
CCK (Clay-Coated Kraft) Release Liner Clay coating provides superior silicone holdout and surface smoothness compared to SCK. CCK paper release liners are preferred for applications demanding high print quality, very smooth adhesive transfer surfaces, or more exacting release uniformity.
MG Kraft (Machine Glazed Kraft) Release Liner One-side-smooth kraft paper offering a strong, flexible, and cost-effective release liner base. Commonly used in food service, industrial tape, and packaging applications where a sturdy, economical paper release liner is appropriate.
Bleached Kraft Release Liner Bright white bleached kraft offers a clean, high-appearance surface combined with good strength. Used in premium label constructions, medical packaging, and retail applications where the visual quality of the release liner matters to the end product.
Densified / Saturated Paper Release Liner Resin-saturated or densified papers offer enhanced moisture resistance and mechanical durability for demanding industrial, outdoor, and specialty release liner applications where standard paper substrates would not hold up under process or environmental conditions.
PE-Coated / Film-Laminated Paper Release Liner Polyethylene-coated paper release liners combine the economics of paper with enhanced moisture resistance and improved silicone anchorage — ideal for demanding wet-environment applications or processes where a hybrid paper-film construction provides the best balance of cost and performance.

Why North American Converters Choose Fox River Associates as Their Release Liner Supplier
For North American converters evaluating release liner suppliers, the choice comes down to reliability, expertise, and responsiveness. Fox River Associates delivers on all three — and has done so consistently for more than 35 years.
Release Liners Only — Complete Focus, Zero Distraction Our entire business is release liners — film and paper. We are not a broad-line distributor that happens to stock release liners. That singular focus makes us more knowledgeable, better stocked, and more immediately responsive than any generalist competitor. When you call Fox River Associates with a release liner question, you are speaking with people whose only job is release liners.
Shortest Lead Times in the Industry We maintain deep stocked inventory across our full product range specifically so our customers never have to wait. Our lead times are the shortest in the release liner industry — because in converting, production downtime is never acceptable and supply delays have real consequences.

ISO 9001:2015 Certified — Quality You Can Count On
Fox River Associates is ISO 9001:2015 certified — the globally recognized standard for quality management systems. For converters, sourcing from an ISO 9001:2015 certified release liner supplier means you are collaborating with a company that has demonstrated documented, audited, and rigorously maintained quality processes.

Production stoppages caused by release liner shortages are among the most preventable disruptions a converting operation can face — and Fox River Associates has built its inventory model specifically to eliminate that risk for our customers. We carry ample stocked inventory across our full range of film release liners and paper release liners to ensure that when you need product, it is available and ready to ship.
We understand that converting operations run on tight schedules, and that a missing release liner can cascade into significant downstream costs. Our deep inventory positions — combined with the shortest lead times in the release liner industry — mean that Fox River Associates’ customers can count on us to have what they need when they need it. For customers with predictable high-volume requirements, we work proactively to align our inventory to your anticipated consumption, providing the supply assurance your operation deserves.
