摘要： [Problem] Upon manufacturing a heat-resistant container using PET sheet, high heat-resistance is made sure without stretching operation. [Solving Means] The method comprises a molding sheet-making process, wherein a sheet is made including organic acid metal salt particulates produced by allowing to react an inorganic basic material or carbonate being solid at ordinary temperature with an organic acid being solid at ordinary temperature in the equivalent relationship, and a container-molding process, wherein, the molding sheet made in the molding sheet-making process is heated to 80- 130°C, formed into a container shape by a vacuum or vacuum-pressure forming machine using a mold, and heat-set by keeping at 130-220°C in the same mold, and the container formed in the container-molding process has a crystallinity of 18 % or more represented by the following formula.
