[Problem] Upon manufacturing a heat-resistant container using nPET sheet, high heat-resistance is made sure without stretching noperation. n n [Solving Means] The method comprises a molding sheet-making nprocess, wherein a sheet is made including organic acid metal salt nparticulates produced by allowing to react an inorganic basic nmaterial or carbonate being solid at ordinary temperature with an norganic acid being solid at ordinary temperature in the equivalent nrelationship, and a container-molding process, wherein, the nmolding sheet made in the molding sheet-making process is heated nto 80 - 130℃, formed into a container shape by a vacuum or nvacuum-pressure forming machine using a mold, and heat-set by nkeeping at 130 - 220℃ in the same mold, and the container formed nin the container-molding process has a crystallinity of 18 % or more nrepresented by the following formula. |
