Stretched Film of Olefin Polymer |
摘要 |
The present invention aims at providing a stretched film of an olefin polymer excellent in anti-static property, which is obtained from an olefin polymer composition comprising an olefin polymer and potassium salt of an ethylene-unsaturated carboxylic acid copolymer, and a gist in construction resides in a stretched film of an olefin polymer, which has been obtained from an olefin polymer composition (C) comprising an olefin polymer (A) and potassium salt of an ethylene-unsaturated carboxylic acid copolymer (B) and has been stretched at a stretching factor in terms of plane factor of at least 3 times. Stretching is preferably biaxially stretching and the olefin polymer composition (C) is preferably comprised of 99-60% by weight of the olefin polymer (A) and 1-40% by weight of potassium salt of an ethylene-unsaturated carboxylic acid copolymer (B).
