RESIN COMPOSITION FOR DRAW MOLDING, DRAW-MOLDED CONTAINER AND METHOD FOR MANUFACTURING DRAW-MOLDED CONTAINER

摘要

PPROBLEM TO BE SOLVED: To provide an aliphatic polyester resin composition which is excellent in draw molding processability and can prepare a draw-molded container having enough heat resistance and gas barrier properties. PSOLUTION: A resin composition for draw molding is characterized in that the resin composition comprises an aliphatic polyester as the main component, and the time when the heat release value of isothermal crystallization at a crystallization temperature +20C measured by a differential scanning calorimeter (DSC) shows the maximum value is 1.5-100 minutes. In addition, a method for manufacturing the draw-molded container is characterized in that this resin composition is draw-molded at a temperature within a range of the crystallization temperature of this resin composition 20C, and at the same time with the draw molding or after draw molding, the crystallization is accelerated by heat treatment within the same temperature range.
