PROBLEM TO BE SOLVED: To provide a polyethylene-based resin for biaxial orientation, having a wide temperature range enabling orientation, enabling stable molding and capable of providing a film excellent in physical properties such as haze, impact strength and tear strength, a polyethylene resin composition for biaxial orientation containing the polyethylene-based resin and an oriented film. SOLUTION: In the polyethylene resin for biaxial orientation, the melt index is 0.5-2.0 g/10 min and the density is 0.905-0.920 g/cm<SP>3</SP>and inclination (elution amount/temperature) of melted component amount in 40-70% melted component amount by a temperature-raising and fractionating method is 2.0-3.3%/°C and a high-density polyethylene component amount in TREF elution curve of the temperature-raising and fractionating method is 8-25%. The polyethylene-based resin composition for biaxial orientation comprises the polyethylene-based resin. The film is obtained biaxially orienting the polyethylene-based resin or the polyethylene-based resin composition. COPYRIGHT: (C)2004,JPO&NCIPI |
