MOLDING METHOD OF HEAT AND PRESSURE RESISTANT PET CONTAINER

摘要

A molding method of a heat and pressure resistance PET(Polyethylene Terephthalate) container for cooling beverage is provided to secure enough pressure and heat resistances and handling stability for beverage filling and packing and to reduce the amount of resin per container. A molding method of a heat and pressure resistance PET container for cooling beverage using biaxial stretching method is characterized in that the horizontal elongation ratio of perform ranges from 2.1 to 2.3 and the longitudinal elongation ratio of perform ranges from 3.3 to 3.8. The average thickness of the heat and pressure resistance PET container is 0.35~0.45mm.
