Title:
PROPYLENE POLYMER COMPOSITION, FILM, STRETCHED FILM, SHRINK FILM, AND METHOD FOR PRODUCING SHRINK-WRAPPED BODY
Document Type and Number:
WIPO Patent Application WO/2007/088775
Kind Code:
A1
Abstract:
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.
