Release liner products are used in dramatically different applications from industry to industry — and often even within a single industry. A release liner that performs perfectly in one application can be entirely wrong for another.
Fox River Associates is an experienced, proven release liner supplier that understands the requirements of the industries we serve. Our release liner offering includes a full range of base materials for both film release liner and paper release liner constructions, along with specialty substrates for applications that fall outside standard specifications. That breadth — combined with more than 35 years of experience focused exclusively on release liners — is what makes Fox River Associates a premier release liner supplier to converters throughout the United States, Canada, and Mexico.
Why Does the Base Substrate Matter So Much in a Release Liner?
The base substrate is the foundation of every release liner, and it drives many performance characteristics that follow. When considering which release liner to use in your application, Fox River Associates helps you identify the conditions your product will be exposed to and the performance requirements the base substrate must meet. It's important to consider how the release liner will be processed, how it will function as a carrier during coating or lamination, and how it will hold up as it moves through subsequent processes on its way to your customer.
Both appearance and functionality of the base substrate play a role in selecting the right release liner. Will the release liner be exposed to high temperatures during your process? Does the application require stiffness for layflat performance or to support a heavy coat weight? Are moisture conditions — either in the manufacturing environment or in storage — a factor you need to plan around? These questions determine whether a film release liner or a paper release liner is the better starting point, and which specific substrate within that category is the right fit.
Fox River Associates approaches substrate recommendations like a funnel. We start with the full range of available paper release liner and film release liner options, and by asking the right questions about your application, process conditions, temperature exposure, moisture sensitivity, and release requirements, we narrow that list down to the substrates most likely to succeed. This often results in recommending more than one release liner option so you can trial and compare performance directly on your equipment before committing to a final specification.

What Substrate Options Does Fox River Associates Offer?
Fox River Associates offers a full breadth of paper substrates for paper release liners and film substrates for film release liners, along with specialty substrates developed for applications that fall outside standard product lines. This depth of offering is a core reason converters across North America consider Fox River Associates a premier release liner supplier — regardless of your industry or application, we have a substrate built to match the requirement.
Base films used in film release liners offer variety in thickness, strength, color and clarity, die-cuttability, flexibility and conformability, temperature resistance, and cleanliness. Film release liners deliver strong durability and hold up well against environmental exposure, which makes them a preferred choice for demanding or high-temperature applications. Fox River Associates' siliconized film release liner offering includes Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polypropylene (PP), Polyester (PET), specialty coextruded films, and embossed film (PE) constructions.
Paper release liners come in a range of weights, and the base papers are available in poly-coated and direct-coated versions. Paper release liners typically offer improved stiffness, strength, kiss-cuttability, strong ink holdout, and — depending on the substrate — good layflat characteristics, making them well suited to tape, and graphic arts applications where precision converting matters. Fox River Associates' siliconized paper release liner offering includes Glassine, Super Calendered Kraft (SCK), Poly Coated Kraft (PCK), Clay Coated Kraft (CCK), Machine Glazed Kraft (MGK), and moisture-stable and specialty base papers.
Beyond substrate selection, Fox River Associates brings deep working knowledge of release coatings, adhesives, converting requirements, die-cutting behavior, storage conditions, and end-use application demands. It's this combined expertise — not substrate options alone — that allows our team to identify the applicable release liner options for every specialized application our customers bring to us.

Why Should North American Converters Choose Fox River Associates as Their Release Liner Supplier?
Release liners are the only business Fox River Associates is in. For more than 35 years, we've focused exclusively on release liner substrates, coatings, adhesives, and converting requirements. This focus makes us a stable, dependable partner, and it's why converters across the United States, Canada, and Mexico rely on us as their release liner supplier of choice.
Our focus also shows directly in how we serve you. Fox River Associates offers the shortest lead times in the release liner industry, supported by a service program built specifically around converter needs. We maintain stocked inventory so that release liner is available in large roll quantities when you need it to keep a production run moving — we never want your operation to be at risk simply because release liner wasn't on hand. At the same time, we offer small minimum order quantities, making Fox River Associates a strong fit for startups, emerging applications, and small to medium-sized converters who need flexibility without being locked into large-volume commitments.
Fox River Associates is also certified ISO 9001:2015. This certification matters to converters because it confirms our quality management systems, documentation practices, and process controls are independently verified and consistently maintained — so the release liner substrate you receive performs the same way order after order, year after year.
We primarily serve converters located in the United States, Canada, and Mexico, and our inventory, logistics, and service programs are built specifically to support this North American manufacturing base.
How Do I Choose the Right Film or Paper Release Liner for My Application?
Choosing the highest-performing release liner starts with a conversation. Our responsive, experienced team communicates with customers to understand the specific demands of their application — coating method, temperature exposure, die-cutting requirements, storage conditions, and end-use environment — before recommending a substrate. Because we carry broad range of paper release liner and film release liner options, we're frequently able to recommend more than one release liner for you to trial, so you can determine what performs best rather than relying on a single default recommendation.
