UNIAXIALLY STRETCHED POLYPROPYLENE FILM |
摘要 |
To provide a uniaxially oriented polypropylene-based film excellent in tensile elongation along the TD direction and transparence, and generating less fibers when it is torn, a film-forming material which comprises a polypropylene-based resin material consisting of 40 to 95% by weight of crystalline polypropylene, and 60 to 5% by weight of propylene- alpha -olefin copolymer dispersed as particles in the crystalline polypropylene is uniaxially oriented to afford a uniaxially oriented polypropylene-based film, wherein the particles of the copolymer have an aspect ratio (L/D) of mean dispersed particle length (L) to mean dispersed particle diameter along the film thickness direction (D) of 100 or more in a cross section of the film along the MD direction, and the mean dispersed particle diameter of 0.10 mu m or less. <IMAGE> |
