What Is A Release Liner?
A release liner is a product that carries a sticky substrate (pressure sensitive adhesive or chemical compound) 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 whatever it is carrying 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 are often coated with silicone release coatings, which allows whatever the liner is carrying to release when the time is right. However, this release 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.

Multiple End Use Market Applications
Medical markets utilize film and paper release liners for applications including electrodes, wound dressings, transdermal drug delivery, wearable devices, monitoring devices and biomedical. 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 and recreation applications utilize composite release liners during the manufacture of 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.
Pressure-sensitive adhesives require the use of a liner to carry the adhesive and facestock through converting and application. Pressure-sensitive tapes, labels and graphics are applications where strength of the paper or film release liner is important for adhesive coating, die-cutting and converting. In the case of labels, the release liner must be designed to perform in high speed automated application equipment.
