METHOD FOR PRODUCING THERMOFORMED ARTICLE OF STYRENE RESIN, MOLDING, AND CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a thermoformed article of a styrene resin which is excellent in oil resistance and appearance and maintains a balance with strength, its molding, and its container.

SOLUTION: In the method for producing the molding obtained by thermoforming a sheet of the styrene resin, the molding after the thermoforming is radiation-heated by a heater of the maximum energy wavelength being in a range of a wavelength zone where the absorption wavelength of its used resin becomes maximum±1μm.
