Abstract | Provided herein is a thermoplastic adhesive composition comprising an ethylene acid copolymer, an ethylene alkyl acrylate copolymer, and a functionalized ethylene copolymer that may be directly copolymerized or a graft copolymer of a polyolefin base with a graft comonomer. Further provided are multilayer films comprising the thermoplastic adhesive composition and coextrusion processes for producing these films. The multilayer films are useful as packaging materials and in particular as food packaging materials.
L'invention concerne une composition adhésive thermoplastique comprenant un copolymère d'acide-éthylène, un copolymère d'acrylate d'alkyle-éthylène, et un copolymère d'éthylène fonctionnalisé qui peut être directement copolymérisé ou un copolymère greffé d'une base de polyoléfine avec un comonomère greffé. L'invention concerne en outre des films multicouches comprenant la composition adhésive thermoplastique et des procédés de coextrusion permettant de produire ces films. Les films multicouches sont utiles en tant que matériaux de conditionnement et en particulier en tant que matériaux de conditionnement de produits alimentaires. |
