PURPOSE: To provide the titled compsn. suitable for use in the production of wrapping film, surface-protective film and overlay film for plywood, consisting of high-pressure polyethylene homopolymer or copolymer and two specified kinds of ethylene/α-olefin copolymers having different densities and MI's. n CONSTITUTION: The titled polyethylene resin compsn. is obtd. from three components of high-pressure polyethylene (A), an ethylene/α-olefin copolymer (B) having an MI of 10g/10min or above and a density of less than 0.928g/cm 3 (e.g. a copolymer of ethylene with a 3W20C, pref. 4W12C α-olefin, or low-pressure or moderate-pressure linear polyethylene copolymer) and an ethylene/α- olefin copolymer (C) having an MI of less than 10g/10min and a density of 0.928g/cm 3 or above. Pref. the combined quantity of components B and C is 20W55pts.wt. per 100pts.wt. of the combined quantity of components A, B and C, and the quantity of component B is at least 10pts.wt. n COPYRIGHT: (C)1984,JPO&Japio |
