PURPOSE:To improve tear strength, stretching irregularity and film thickness irregularity by uniaxially orienting film or sheet obtained by the inflation molding of a compsn. consisting of a polyolefin resin with specific density and a specific melt index, a filler, a plasticizer and a radical generator in a taking- over direction thereof. CONSTITUTION:A film or sheet obtained by the inflation molding of a compsn. consisting of 100 pts.wt. of a polyolefin resin with density of 0.930g/cm<3> or less and a melt index of 2g/10min or less, 100-400 pts.wt. of an optical filler, 0.1-100 pts.wt. of a plasticizer represented by formula (Ar)n-B-(R)m (wherein Ar is a carboxylic acid residue or an alcohol residue having an aromatic group, B is a polyvalent carboxylic acid residue or a polyvalent alcohol residue, R is an aliphatic carboxylic acid residue or an aliphatic alcohol residue, n is 1-8 and m is 0-7) and 0.0001-0.1 pts.wt. of a radical generator is uniaxially oriented in the taking-over direction thereof. |
