摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a hot filling bottle having heat resistant to stand hot filling (high temperature filling) at 85-90°C; manufacturing method for bottle product and hot filling bottle.;SOLUTION: First a preform 10 including a polyethylene terephthalate layer 12a is prepared. Subsequently, the preform 10 is heated, and then the heated preform 10 is subjected to blow molding by a blow molding die 54a. In this case, the heating temperature of the preform 10 is set to 115-140°C, and the temperature of the blow molding die 54a is set lower than the glass transition temperature of polyethylene terephthalate by 10°C or more. Thus, it is possible to obtain the hot filling bottle 20 which may stand hot filling (high temperature filling) at 85-90°C.;COPYRIGHT: (C)2010,JPO&INPIT
