Abstract

L'invention concerne les films de polypropylène thermoscellables pour l'emballage comportant un film support mono ou bi-orienté, essentiellement en polypropylène revêtu sur l'une au moins de ses faces d'une composition thermoscellable, caractérisé en ce que ladite composition comporte de 15 % à 85 % en poids d'un premier copolymère sensiblement linéaire et principalement statistique d'éthylène et d'une autre alpha -oléfine, ayant au moins 3 atomes de carbone par molécule et représentant de 10 % à 25 % en poids du premier copolymère, et de 85 % à 15 % en poids d'un second copolymère principalement statistique de propylène et d'une alpha -oléfine ayant 2 ou au moins 4 atomes de carbone et représentant de 2 % à 12 % en poids de ce second copolymère.
