Differential release liners play a critical role in the coated product supply chain and adhesives product development. They are vital to product performance and often serve as crucial components in the manufacture of tapes, fiber composite, and medical materials.
A differential release liner is a paper or filmic web coated on both sides with silicon-based release coatings that are designed to provide differing release values to the specific adhesives applied to them. Differential release liners provide a means to protect and transport a pressure-sensitive adhesive (PSA), fiber composite material or heat-sealable adhesive to its application point, where the liner can be removed to leave only the adhesive in place.
