Biodegradable molded article and container using the molded article

摘要

A biodegradable molded article and a container using the molded article, exhibiting an improved heat resistance. The molded article is obtained by injection molding a polylactic acid resin, wherein the molded article comprises poly-L-lactic acid containing less than 4 mol% of D-lactic acid. The molded article has a crystallized portion at least locally, having a ratio of the crystallizing heat quantity to the melting heat quantity (|”Hc|/”Hm), which ratio is not more than 0.7 in a temperature rising chart obtained by differential scanning calorimetry (DSC).
