Abstract
It is an object of the present invention to provide a novel production method which makes it possible to obtain a molded product containing a P3HB-based resin through an injection blow molding method and a technique for using such a method. The object is achieved by providing a method for producing a molded product containing a P3HB-based resin, the method including the steps of: (A) plasticizing a resin composition containing a P3HB-based resin; (B) subjecting the plasticized resin composition obtained in the step (A) to injection molding to obtain a preform; and (C) subjecting the preform obtained in the step (B) to blow molding to obtain a molded product.
