Release liner, also known as backing paper or release paper, is a material commonly used in various industries, including manufacturing, packaging, and labeling. It plays a crucial role in the production and application of adhesive products.
The purpose of a release liner is to provide a temporary protective layer to the adhesive surface. It is typically made of paper or film and is coated with a release agent on one or both sides. The release agent allows for easy removal of the liner from the adhesive without leaving any residue.
