ORIENTED FILM

PROBLEM TO BE SOLVED: To provide an oriented film excellent in transparency, rigidity, balance of tear strength in the longitudinal direction (MD) and the lateral direction (TD), impact resistance, heat-sealing characteristics, shrink pack characteristics and the like. SOLUTION: This oriented film is formed of a resin composition consisting of 50-95 pts.wt. of a constituent (i) with density of 890-940 kg/m3and 5-50 pts.wt. of a constituent (ii) (the sum of the constituent (i) and the constituent (ii) is 100 pts.wt.). The constituent (i) consists of 5-95 pts.wt. of an ethylene-α-olefin copolymer (I) with density of 880-925 kg/m3and 5-95 pts.wt. of an ethylene-α-olefin copolymer (II) with density of 926-960 kg/m3(the sum of copolymers (I) and (II) is 100 pts.wt.). The constituent (ii) is a high-density polyethylene (III) consisting of an ethylene polymer or an ethylene-α-olefin copolymer with density of 951-970 kg/m3. COPYRIGHT: (C)2009,JPO&INPIT
