FILMS PREPARED FROM ETHYLENE COPOLYMERS

摘要

chemistry of polymers. SUBSTANCE: described are polymeric films consisting of at least one layer made of ethylene copolymer or triple ethylene copolymer. Said layer has impact strength of more than 100 g/mil determined by procedure ASIM D-1709. Method A using fall height of 112 cm. Content of ethylene copolymer or triple ethylene copolymer in said layer is at least 80 wt %. Said ethylene copolymer has composition distribution width value within 50-90 % and Mz/Mw of about less than 2.0. High tensile strength, impact strength and resistance to puncture of films made of said polymers made then suitable for manufacturing stretching film cargo packets. EFFECT: improved properties of the films. 12 cl, 6 dwg, 17 tbl
