BLOW MOLDING METHOD AND MACHINE FOR PRODUCING PASTEURIZABLE CONTAINERS

摘要

A blow molding machine for producing a biaxially oriented, heat set plastic container, including a blow mold; a high-pressure fluid source; a high-temperature fluid source; a blow core assembly having an exhaust; and a controller coupled to the high-pressure fluid source, to the high-temperature fluid source, and to the exhaust. The PET containers produced by the machine have an average sidewall crystallinity greater than about 30%, which allows the PET container to maintain its material integrity during any subsequent pasteurization or retort process of the contents in the PET container, and during shipment of the PET container.
