Release liner is a carrier web material made up of paper or plastic. Release liners are coated on one or both the sides with release agent (chemical used to prevent one material from bonding to surfaces of another material). These releasing agents provide a releasing effect when kept in contact with any kind of stick materials.
Adhesive (substance when applied to the surfaces of any materials binds them together and resists separation) and mastic (kind of gum) are of the stick material used for releasing agents. Release liners are available in different colors in the market; it can be a printed or non-printed release liner. Commercial coating companies are engaged in the manufacturing of release agent, providing unique solutions to their clients, based on a wide variety of substrates used to manufacture releasing agents. Commonly used releasing agents for release liner are cross linkable silicone and other coating materials that have low surface energy.
