  • Method for producing heat-set base of a plastic container
    Publication number: 20050260370
    Abstract: A method for making a blow molded plastic container that can withstand the rigors of pasteurization of retort processing. The method includes introducing an injection molded plastic preform into a blow mold; circulating heated oil through the sidewall mold halves at a temperature of at least about 225° F. and circulating heated oil through the base push up at a temperature of at least about 275° F. The container is blow molded from the preform and heat set within the mold. The container has enhanced crystallinity in the base as compared to when heated water is circulated through the mold.
