<p>PROBLEM TO BE SOLVED: To provide a method for orienting blow molding to manufacture a transparent oriented blow molded multilayer bottle having an excellent transparency, impact resistance, gas barrier properties, heat resistance, low- temperature resistance, ultraviolet absorbability, excellent alkali resistance in the case of alkali cleaning to be executed in the case of recovering from a market, cleaning, refilling and reusing, preservation stability of a content and perfume retentivity required for a bottle or the like for food and the transparent oriented blow molded multilayer bottle. SOLUTION: In the method for manufacturing the transparent oriented blow molded multilayer bottle comprising the step of orienting blow molding a preform having (A) an outer layer made of a polycarbonate resin and (B) an inner layer made of a polyethylene naphthalate resin, a thickness of the polycarbonate resin layer of the preform is 0.5 to 30 mm, and a thickness of the polyethylene naphthalate resin layer is 0.5 to 6 mm.</p> |
