A liner, also known as release paper or release film, is a protective layer of material that is applied to the adhesive side of an adhesive tape. Its main function is to protect the adhesive surface until it is used and to enable easy handling and clean processing. But the potential of a liner goes far beyond this basic function.

Liners can be made of various materials such as paper, polypropylene (PP), low-density polyethylene (LDPE) and polyethylene terephthalate (PET). Liners are available in different thicknesses depending on requirements. We work with liner materials ranging in thickness from 50 to 142µm to meet the specific requirements of different applications. They can also be siliconised on one or both sides. The release values of the silicone coating determine how easy or difficult it is to remove the liner.
 

A common misconception is that silicone coatings can be problematic as they are seen as potential contaminants. However, liners actually use bonded silicones, which ensure that the tape cover releases completely and cleanly from the tape without compromising functionality.
