<p><P>PROBLEM TO BE SOLVED: To provide a biodegradable resin-made vessel having both excellent heat resistance and a gas barrier property. <P>SOLUTION: The vessel made by molding the biodegradable resin is characterized in that the molded resin has a degree of crystallinity of not less than 15% measured by an X ray diffraction method, that the molded resin showsΔH (endothermic heat of fusion-exothermic heat of crystallization) of not less than 15J/g in the first temperature increase by a DSC method, that a water vapor barrier property per unit (100 g/m<SP>2</SP>) is not more than 300 g/day/m<SP>2</SP>, and that the biodegradable resin is mainly composed of a polylactic acid-based resin. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
