Abstract
A propylene polymer resin composition characterized in that it has a flexural modulus in the range of 200 to 1200 MPa and a melt flow rate (MFR) measured at 230° C. in the range of 0.1 to 30 g/min, and a melt tension (MT (mN)) and an MFR (g/10 min) measured at 230° C. satisfy a specific formula, and a sheet or film obtained therefrom. According to the present invention, there is provided a polyolefin film which is excellent in transparency and especially excellent in transparency and low-temperature heat shrinkable properties after stretching.
