Abstract
The present invention provides blow bottles of a polyolefin resin having excellent transparency by the utilization of characteristics of the polypropylene. That is, they are the blow bottles of a polyolefin resin obtained by subjecting, to an extrusion blow molding method, a composition having a melt flow rate at 230.degree. C. of 0.5 to 10 g/10 minutes prepared by blending (A) 70 to 99.99% by weight of a propylene random copolymer of multi-component system having a crystalline melting point of 110.degree. to 145.degree. C. and containing 3 to 10% by weight of ethylene units with (B) a certain amount of two or three kinds of polyethylenes selected from 15 to 0.01% by weight of a straight-chain low-density polyethylene, 4 to 0.01% by weight of a low-density polyethylene and 4 to 0.01% by weight of a high-density polyethylene.
