Title
(EN) METHOD FOR PRODUCING A MULTILAYER FILM
(FR) PROCÉDÉ DE PRODUCTION D'UN FILM MULTICOUCHE
Abstract
(EN)
The present invention relates to a method for producing a multilayer film comprising at least two layers joined by means of a two-component adhesive, comprising the following steps: - spreading a first component A of a two-component adhesive on a first face of a first layer of film; - spreading a second component B of the two-component adhesive on a first face of a second layer of film; - bringing the aforesaid first and second faces of the first and second layers into mutual contact joining the components (A) and (B) to form an adhesive and join the two layers in a multilayer film; and - winding the multilayer film obtained.
(FR)
La présente invention concerne un procédé de production d'un film multicouche comprenant au moins deux couches assemblées au moyen d'un adhésif à deux composants, comprenant les étapes suivantes : - étaler un premier composant A d'un adhésif à deux composants sur une première face d'une première couche de film; - étaler un second composant B de l'adhésif à deux composants sur une première face d'une seconde couche de film; - amener les première et seconde faces susmentionnées des première et seconde couches en contact mutuel de façon à combiner les composants (A) et (B) pour former un adhésif et assembler les deux couches en un film multicouche; et - enrouler le film multicouche obtenu.
