To improve the productivity of a plastic bottle for liquid medicine by shortening its molding time gained through shortening required cooling down time of the plastic material in the molding process keeping its outstanding transparency proper to the plastic bottle made of a polypropylene of syndiotactic configuration and further obtain much more improved surface by preventing rough skin phenomenon from occurring.

A plastic bottle 1 for liquid medicine consist of a base resin layer of an elastic synthetic resin composed substantially of a polypropylene of syndiotactic configuration and an outer surface layer to touch the inside of the mold on blow molding made from the mixture of a polypropylene of syndiotactic configuration and a random copolymer of propylene and ethylene of isotactic configuration containing 1-9% weight of ethylene.
