PROBLEM TO BE SOLVED: To provide a biodegradable polyester composition effectively accelerating crystallization of a biodegradable polyester such as polylactic acid even when the quantity to be added is small. SOLUTION: The biodegradable polyester composition contains 0.1-10 mass% polyglycolic acid. Even when the quantity to be added is small, crystallization rate is sufficiently prompted and the cycle of thermoforming is shortened. The thermoforming-formed product is utilized for various kinds of applications such as vessels, dishes, packaging materials or industrial materials. COPYRIGHT: (C)2009,JPO&INPIT
