Abstract

La présente invention concerne une composition de film d'étanchéité comportant au moins deux matériaux constitutifs de polymère d'éthylène. Selon un mode de réalisation, la présente invention concerne une structure multicouches présentant des propiétés d'étanchéité équilibrées et comportant une couche d'étanchéité et une couche de polypropylène, la couche d'étanchéité comprenant une composition de polymère ou est fabriquée à partie de celle-ci, cette composition présentant des caractéristiques particulières de poids moléculaire et un second polymère d'éthylène. Selon un mode de réalisation préféré, la présente invention concerne un film polyoléfinique à densité moyenne et une composition caractérisée par un excellent équilibre entre une température d'initiation d'étanchéité et un module de film amélioré. Le film et la composition comprennent au moins un polymère d'éthylène basse densité ramifié de façon homogène et au moins un polymère d'éthylène basse densité ramifié de façon homogène ou hétérogène ou sont fabriqués à partir de ceux-ci. La présente invention est particulièrement utilisée dans des applications nécessitant des temps de prise d'étanchéité rapide et une bonne stabilité dimensionnelle d'un emballage, par exemple, emballage de cuisson, emballage rempli à chaud, sachets pour matière fluide, emballage à contenu comprimé, emballage par film rétrécissable et emballage par film barrière rétrécissable ainsi que des structures de film de polypropylène (BOPP) orientées biaxialement.
