<p>At least an outer layer of a plastic container is formed of a blend including an ethylene-propylene block copolymer containing 3 to 10 % by weight, particularly 5 to 9 % by weight of ethylene and a melt flow rate of 0.8 to 10 g/10 min. and a polyethylene having a given density at a weight ratio of 9:1 to 5:5. A plastic container made of an olefin resin having a frosted or matted appearance can be manufactured with excellent moldability without requiring any special working such as sand blasting the cavity surface of a mold. The container will gives an impression of shade off, depth and high grade.</p> |
