<p>A thermoplastic olefin resin composition composed of a blend of (i) 5 to 95% by weight, based on the weight of the blend, of a random copolymer consisting essentially of 55 to 85 mole% of propylene and 45 to 15 mole% of 1-butene and having a heat of fusion of 10 to 80 joules/g determined by differential thermal analysis using a differential scanning calorimeter, and (ii) 5 to 95% by weight, based on the weight of the blend, of an isotactic propylene resin containing 0 to 10 mole% of another alpha -olefin and having a melting point of 135 DEG to 165 DEG C. and a melt index, measured at 230 DEG C., of 0.1 to 20; and a laminated olefin resin film or sheet thereof.</p> |
