ABSTRACT:
A polyester resin composition comprises: an aliphatic polyester having a number-average molecular weight (Mn) in a range of 10,000 to 100,000; and a crystalline nucleating agent, wherein the aliphatic polyester and the crystalline nucleating agent are mixed in such that a half value width of an exothermic peak based on an annealing crystallization of the aliphatic polyester measured by differential scanning calorimetry in an atmosphere of nitrogen at a cooling rate of 3K/minute is not more than 15K. This polyester resin composition has a biodegradability and a high crystallization rate. The polyester resin composition also has excellent mechanical properties and eliminates a precise temperature control during a molding process which saves labor force resulting in desirable moldability and productivity. For the described beneficial properties, the polyester resin composition can be readily processed into a fiber, a molded article, sheet, film and the like. Accordingly, a film made of the polyester resin composition can be effectively used for disposable packing materials, miscellaneous goods for daily use, and the like.
