Title
(EN) MULTILAYER POLYMER FILM
(FR) FILM POLYMÈRE MULTICOUCHE
Abstract
(EN)
A multilayer film comprising at least two layers, a layer (B) and an outer layer (A), wherein outer layer (A) comprises a multimodal polymer of ethylene with at least two different comonomers selected from alpha-olefins having from 4 to 10 carbon atoms, which multimodal polymer of ethylene has a density of 910 to 935 kg/m3, and a Mw/Mn of 2 to 8; and said layer (B) comprising a multimodal ethylene copolymer of ethylene and one C4-10 comonomer or a multimodal ethylene terpolymer of ethylene and at least two C4-10 comonomers, or a mixture thereof, wherein said multimodal ethylene copolymer or terpolymer has a density of 910 to 940 kg/m3 and an Mw/Mn of 9 or more.
(FR)
L’invention concerne un film multicouche comprenant au moins deux couches, une couche (B) et une couche externe (A). La couche externe (A) comprend un polymère multimodal d'éthylène ayant au moins deux comonomères différents choisis parmi les alpha-oléfines ayant de 4 à 10 atomes de carbone, le polymère multimodal d'éthylène ayant une densité comprise entre 910 et 935 kg/m3, et un Mw/Mn compris entre 2 et 8 ; et ladite couche (B) comprend un copolymère d'éthylène multimodal d'éthylène et un comonomère en C4-C10 ou un terpolymère d'éthylène multimodal d'éthylène et au moins deux comonomères en C4-C10, ou un mélange correspondant, ledit copolymère ou terpolymère d'éthylène multimodal ayant une densité comprise entre 910 et 940 kg/m3 et un Mw/Mn supérieur ou égal à 9.
