ABSTRACT:
An injection molded preform for making a stretch blow molded container having an overall stretch ratio of from about 12 to about 16, wherein the overall stretch ratio is a product of a hoop stretch ratio and an axial stretch ratio, wherein the hoop stretch ratio is from about 5.6 to about 6.5, wherein the axial stretch ratio is from about 2.4 to about 2.7, and wherein the preform comprises a CG PET Copolymer having a free blow volume of from about 650 to about 800 ml measured at 100° C. and 90 psi using a 25 gram weight preform designed for a 500 ml container with a maximum diameter of 65 mm and a height of 200 mm from below the container finish and having a hoop stretch ratio of 5.5 and an axial stretch ratio of 2.6. This invention also relates to a method of making such preforms and stretch blow molded containers and methods of making the same.
