PROPYLENE POLYMER COMPOSITION, FILM, STRETCHED FILM, SHRINK FILM, AND METHOD FOR PRODUCING SHRINK-WRAPPED BODY |
| 摘要 |
<p>Disclosed is a propylene polymer composition characterized by having a bending modulus of 200-1200 MPa and a melt flow rate (MFR) measured at 230°C of 0.1-30 g/min. The propylene polymer composition is also characterized in that the melt tension (MT(mN)) measured at 230°C and the MFR (g/10 min) satisfy a specific formula. Also disclosed is a sheet or film made from such a propylene polymer composition. This propylene polymer composition enables to obtain a polyolefin film which is excellent in transparency, particularly in transparency after stretch, while being excellent in low-temperature heat shrinkage characteristics.</p> |
