Abstract
A blow molding machine for producing a biaxially oriented, heat set plastic container, including a blow mold; a high-pressure gas source; a high-temperature gas source; a fluid source; a mixer coupled to the high-temperature gas source and to the fluid source; a blow core assembly having an exhaust; and a controller coupled to the high-pressure gas source, to the, high-temperature gas source, and to the fluid source. 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.
