Abstract
A thermoplastic olefin resin composition composed of a blend of PA1 (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 PA1 (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.degree. to 165.degree. C. and a melt index, measured at 230.degree. C., of 0.1 to 20; and a laminated olefin resin film or sheet thereof.
