HEAT-RESISTANT AND PRESSURE-RESISTANT SELF-SUPPORTING CONTAINER

摘要

PURPOSE:To manufacture a heat-resistant and pressure-resistant container of a saturated polyester self-supporting container which is biaxially stretching blow molded and of superior resistance to impact and resistance to chemicals. CONSTITUTION:A saturated polyester container with self-supporting bottom structure is biaxially stretching blow molded, and a low stretched areas formed in a central section 3 and/or a central section periphery 4 of the container bottom 2 of the above-said heat-resistant and pressure-resistant self-supporting container 1 and so semicrystallized as to obtain the density of 1.337g/cm<3>-1.360g/ cm<3>.
