PROBLEM TO BE SOLVED: To obtain a composition which can give an oriented polyolefin film excellent in transparency, slipperiness, blocking resistance, scratch resistance, and segregation resistance by mixing a polyolefin resin with microparticles of a specified-functional-group-containing crosslinked polymer and an acid- modified polyolefin resin. SOLUTION: This composition comprises 100 pts.wt. polyolefin resin; 0.05-1.0 pt.wt. microparticles made of a crosslinked polymer containing at least one type of functional groups selected among groups of formulae I to IV (wherein Rs are independently each hydrogen or a hydrocarbon group; and X is Cl or Br) in the polymer chain and having a volume-mean particle diameter of 0.3-10μm; and 0.01-5 pts.wt. acidmodified polyolefin resin having an acid value of 1.0-100 as measured according to JIS K0070. The polyolefin resin is desirably a polypropylene resin. A film made from the composition is oriented at least uniaxially to obtain an oriented polyolefin film. |
