Ethylene-alpha-olefin copolymer composition

Abstract

PURPOSE: A composition having improved hot tack tear strength, transparency, impact strength resistance, etc., obtained by adding an ethlylene vinyl acetate copolymer with high content of vinyl acetate to a specific ethylene α-olefin copolymer. CONSTITUTION: (A) 95W60pts.wt. copolymer of ethylene and 4W20C α-olefin, having 0.1W20g/10min melt flow rate, 0.91W0.94g/cm 3 density, and 115W130°C melting point is blended with (B) 5W40pts.wt. ehtylene-vinyl acetate copolymer 0.1W50g/10min flow rate, 0.92W0.98g/cm 3 density, 40W100°C melting point and 10W50wt% vinyl acetate content. Preferably the amount of the component A blended is 90W70pts.wt. and that of the component B is 10W30pts.wt. ≥6C α-olefin is preferable as the α-olefin of the component A. USE: Useful as a packaging film, and a packaging bag in the field of packed frozen food, for moist food, paste food, and oily food. COPYRIGHT: (C)1983,JPO&Japio
