Upon manufacturing a heat-resistant container using PET sheet, high heat-resistance is achieved without a stretching operation. The method comprises a molding sheet-making process, wherein a sheet is made including organic acid metal salt particulates produced by allowing an inorganic basic material or carbonate that is solid at ordinary temperature to react with an organic acid that is 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.

A built-in and process-adaptive formulation of antimicrobial commodity thermoplastic resins with mixed compositions comprising of a polymer, a backbone linker, and a non-labile antifouling and biocompatible coupling agent which is melt-processable and enabled to be manufactured into finished products in the form of solid, monolith, tube, composite, fiber, film, sheet and varnish without the prerequisite of biocides or antimicrobial additives is disclosed. The said formulation is adapted to thermoforming and thermal curing processes including but not limited to melt compounding, spinning, extrusion, molding, compression foaming and drawing. The antimicrobial property is attributed to the persistent formation of a non-stick bacteria-repellent tethered layer in which the antifouling component of the said formulation is heterogeneously phase separated and/or surface migrated to the surface after product forming in order to minimize adsorption and/or colonization of bacteria.
