PROBLEM TO BE SOLVED: To provide a sheet for thermoforming, comprising a polylactic acid resin composition, which has a good thermoforming property even after storage at a relatively high temperature of summer, and to provide a method for producing a molded body formed by molding the sheet obtained by the aforementioned production method.SOLUTION: The method for producing a sheet for thermoforming comprises the following steps (1) and (2). Step (1): a step of preparing an amorphous or a semi-crystalline sheet of a polylactic acid resin composition comprising a polylactic acid-based resin and an amide-based organic crystal nucleating agent. Step (2): a step of storing the sheet obtained in the step (1) at a glass transition temperature (Tg) or less of the polylactic acid resin composition, where the composition is stored for a longer time than the time required where a semi-crystallization time calculated by a method (A) increases by the storage to become 0.7 minute or more and thereafter becomes 0.6 minute or less.SELECTED DRAWING: None |
