Abstract:
The method for producing a multilayer covering film includes having a pressure sensitive adhesive layer protected by a liner with a system for controlling adhesion. The method includes a step of forming the adhesion-controlling system, which includes an operation for selectively positioning a polymeric, non-adhesive material composition in microcavities provided on one face of the liner. The invention also relates to a multilayer film produced using this production method and a method for applying this multilayer film.
