(EN) METALLIZABLE BOPP FILM WITH AN OUTER POLYKETONE LAYER
(FR) FILM EN POLYPROPYLENE (BOPP) METALLISABLE A COUCHE EXTERIEURE EN POLYCETONE
Abstract:
(DE) Die vorliegende Erfindung betrifft heißsiegelbare Verbundfolie, die sich zusammensetzt aus A) einer Basisschicht aus bevorzugt biaxial gerecktem Polypropylen; B) einer Haftvermittlerschicht aus modifiziertem Polyolefin auf mindestens einer Seite der Basisschicht A; C) einer Außenschicht aus einem Copolymer, welches aus einem oder mehreren Olefine und Kohlenmonoxid (Polyketon) besteht und sich auf der/den Haftvermittlerschicht(en) B befindet.
(EN) The invention relates to a heat-sealable composite film comprising A) a base layer of preferably biaxially stretched polypropylene; B) an adhesion-promoting layer of modified polyolefin on at least one side of base layer (A); C) an outer layer of a copolymer consisting of one or several olefins and carbon monoxide (polyketone) located on the adhesion-promoting layer(s) (B).
(FR) L'invention concerne un film composite thermosoudable comprenant: A) une couche de base en polypropylène étirée de préférence biaxialement; B) une couche d'accrochage en polyoléfine modifiée, située sur au moins une face de la couche de base A; C) une couche extérieure consistant en un copolymère comprenant une ou plusieurs oléfines et du monoxyde de carbone (polycétone), qui est située sur la(les) couche(s) d'accrochage B.
