BIAXIALLY ORIENTED POLYPROPYLENE-BASE FILM |
摘要 |
<p>To provide an economically advantageous biaxially oriented polypropylene-based film, which is excellent in straight cuttability along the MD direction, strength along the TD direction and transparency, a film-forming material which comprises a polypropylene-based resin material consisting of 40 to 88% by weight of crystalline polypropylene, and 60 to 12% by weight of propylene- alpha -olefin copolymer dispersed as particles in the crystalline polypropylene is biaxially oriented to afford a biaxially oriented polypropylene-based film wherein the particles of the copolymer have a mean dispersed particle diameter of 0.1 mu m or less along the TD direction.</p> |
