<p>Disclosed is a specific adhesive polyethylene composition comprising Ä1Ü a modified ethylene/ alpha -olefin copolymer resin or elastomer obtained by modifying a specific ethylene/ alpha -olefin copolymer resin or elastomer, each of which comprises ethylene and an alpha -olefin of 3 to 20 carbon atoms, with an unsaturated carboxylic acid or derivative thereof, Ä2Ü an unmodified ethylene/ alpha -olefin copolymer resin and/or an unmodified ethylene/ alpha -olefin copolymer elastomer and Ä3Ü a tackifier. Also disclosed is a multi-layer laminated film of 3 or more layers in which a layer of the above composition is interposed between an ethylene polymer layer and either a polyamide resin layer, an ethylene/vinyl alcohol copolymer layer or a layer of a mixture of polyamide resin and ethylene/vinyl alcohol copolymer. The adhesive polyethylene composition shows excellent adhesion strength to ethylene polymers, polyamide resins and ethylene/vinyl alcohol copolymers, high heat-sealing strength and heat resistance. The multi-layer laminated film shows excellent strength, heat resistance and gas barrier properties, and besides this film has heat shrinkability, so that the film is suitably used as a shrink film.</p> |
