Fox River Associates Getting Started with Release Liners - Paper - Film - Polycoated

Getting Started with 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 30 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.

Multiple End Use Market Applications

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.
