Abstract

L'invention concerne un film composite thermosoudable comprenant un film en polypropylène étiré biaxialement servant de film de base, une couche d'accrochage en polyoléfine modifiée, une couche de barrage au gaz réalisée en un copolymère en éthylène et en monoxyde de carbone et une couche de thermosoudage en polymérisats d'oléfine. Le film de base porte sur au moins une surface une couche combinée éventuellement au moins à orientation monoaxiale, qui comprend: A) une couche extérieure thermosoudable réalisée dans un homo-, co- ou terpolymérisat oléfinique; B) une couche d'accrochage en polyoléfine modifiée; C) une couche de barrage au gaz réalisée dans un copolymère comprenant une ou plusieurs oléfines et du monoxyde de carbone (polycétone); D) une couche d'accrochage en polyoléfine modifiée et E) une couche en polyéthylène et un polymérisat d'éthylène comportant au moins 3 % en poids d'éthylène. Le film de base porte sur au moins une de ses surfaces éventuellement une couche A, une combinaison de couches A à E, A à D ou B et C.
