WHAT ARE RELEASE LINERS?
A release liner is a product that carries a sticky substrate (think adhesives or gooey chemicals) through a manufacturing process until it is ready for its next step. Sometimes called a ‘carrier’ or a ‘backing’ paper/film, release liners hold onto or carry the sticky substrate, until it is ready to be released.
Release liner can be film-based, paper-based, polycoated-paper based, or even have unique substrates, such as metallized papers/films as their base. Release liner substrates have technically engineered release coatings, often silicone, which allows whatever the liner is carrying to release only when the time is right. However, the release from the liner can also be accomplished with non-silicone coatings or even with a surface characteristic of the substrate that doesn’t require a coating at all. These are highly specialized release liners.
Fox River Associates has been a leading supplier of paper release liners and film release liners for more than 35 years. Contact our team today for more information about the release liner that is right for your application. Call us at 1-800-647-6579 or use the form on this page.
Substrates and Coatings
Film release liners offer good durability and perform well when exposed to environmental elements. They have exceptional moisture resistance, dimensional stability, and chemical resistance. Filmic release liners are ideal for high-performance applications such as medical devices and industrial bonding applications. The product offering from Fox River Associates includes a variety of film substrates and thicknesses delivering a range of performance in strength, flexibility, and appearance to ensure you will find the right release liners for your application.
Paper release liners offer temperature resistance, stiffness, and high resistance to many solvent-based coatings. Paper release liners can be designed with low or high internal moisture to deliver improved dimensional stability. The product offering from Fox River Associates includes a variety of paper substrates and calipers delivering a range of performance in strength and appearance to ensure you will find the right release liners for your application.
Paper release liners with a PE extrusion coating (Polycoated Kraft or PCK) deliver improved layflat and dimensional stability while providing a smooth release surface for coatings and adhesives. Graphic applications, sheeted products and other technical specialty products require layflat qualities for coating and converting.
The high moisture stability levels in our PCK liner papers help maintain the form and flatness of the products. Without these benchmark quality properties, moisture can penetrate the liner and create manufacturing and converting issues. The combination of these layflat and dimensional stability characteristics also provides the stability needed so that climate changes do not affect the performance of the coating or the processing.
Fox River Associates offers a full line of release coatings for our filmic release liners and paper release liners. Our offering includes silicone and non-silicone release coatings, as well as specialty release coatings.
Release liners from Fox River Associates can be silicone coated one-side or coated on two-sides with the same or differential release coatings. Some of our many release liner substrates are available with specialty release coatings or no coatings at all. We offer solvent and solventless silicone coatings as well as different fluoro based release coatings.
After learning about the specific requirements and processing conditions, Fox River Associates will recommend the substrate and coating that will help you deliver the best product to your customers.

Where are Release Liners Used?
Pressure-sensitive adhesives require the use of a liner to carry the adhesive and face through converting and application. Pressure-sensitive labels/graphics and self-adhesive tapes are global applications where strength of the liner is important for adhesive coating, die-cutting and converting. In the case of labels, the liner must be designed to perform in high-speed automated application equipment.
Medical and hygiene markets also utilize release liners for applications including electrodes, wound dressings, transdermal patches, diapers, and feminine care products. Medical applications can require higher levels of cleanliness in the manufacturing process, and the products must often meet special regulatory requirements. The removal of the release liner for these products is usually done by hand, often by the consumer, so consistency of release is imperative.
Industrial applications for release liner include building and construction applications such as roofing shingles, weatherproofing and insulation products. The manufacturing of composites for aerospace, wind energy, recreation and automotive applications utilize release liners during the manufacture of composite pre-preg, an early stage of the manufacture of finished composite products. These are highly specialized applications where the liner is exposed to high temperature fluctuations and must maintain its dimensional stability.
