Title (EN) METHOD FOR PRODUCING A MULTILAYER COVERING FILM
(FR) PROCEDE DE FABRICATION D'UN FILM MULTICOUCHE DE RECOUVREMENT
Abstract:
(EN) The present invention relates to a method for producing a multilayer covering film that comprises a pressure sensitive adhesive layer protected by a liner (8) having a system for controlling adhesion (17). According to the invention, the production method includes a step of forming the adhesion-controlling system (17), which comprises an operation for selectively positioning a polymeric, non-adhesive material composition (18) in microcavities (13) provided on one face (11) of the liner (8). The invention also relates to a multilayer film produced using this production method and a method for applying this multilayer film.
(FR) La présente invention concerne un procédé de fabrication d'un film multicouche de recouvrement gui comporte une couche adhésive sensible à la pression protégée par un liner (8) qui est équipé d'un système de contrôle d'adhésion (17). Selon l'invention, le procédé de fabrication comporte une étape de formation du système de contrôle d'adhésion (17) qui comprend une opération de placement sélectif d' une composition polymère d'une matière non-adhérente (18) dans des microcavités (13) ménagées sur face (11) du liner (8). La présente invention porte également sur un film multicouche fabriqué à l'aide du procédé de fabrication et un procédé d'application de ce film multicouche.
