Silicone release liner technology
The silicone release liner is an integral part of a self-adhesive label. This article examines the process and materials used for release liners, then looks at performance characteristics and how these are measured.
A pressure-sensitive label release liner consists of a paper or film coated with a very thin layer of silicone which is laminated to a face material backed by an adhesive coating (Figures 3.1 and 3.2). The silicone coating allows the die-cut adhesive-backed face paper or film to ‘release’ from the liner at the point where the label is applied to a container or other surface.
