POLYOLEFIN RESIN COMPOSITION AND MONOAXIALLY STRETCHED FILM OF POLYOLEFIN |
摘要 |
PURPOSE:To obtain a monoaxially stretched film of a polyolefin having excellent initial tearing property and straight tearing property and a resin composition useful as a raw material of the monoaxially stretched film. CONSTITUTION:This polyolefin resin composition contain 100 pts.wt. of a crystalline polypropylene having 20.960 isotactic index, 6-10g/10min melt flow rate and 2-10 pts.wt. of a polyethylene having 1-50g/10min melt flow rate, 0.900-0.940g/cm<3> density and 0.5-3 pts.wt. of an atactic polypropylene having 5000-25000 molecular weight. The monoaxially stretched film of the polyolefin is obtained by stretching an unstretched film obtained from the polyolefin resin composition to 3-10 times. |
