  • Publication number: 20060257603
    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.

  • Publication number: 20050118371
    Abstract: A container is made from a preform comprising a PET Copolymer comprising a diol component having repeat units from ethylene glycol and a non-ethylene glycol diol component and a diacid component having repeat units from terephthalic acid and a non-terephthalic acid diacid component. The total amount of non-ethylene glycol diol component and non-terephthalic acid diacid component is present in the poly(ethylene terephthalate) copolymer in an amount from about 0.2 mole percent to less than 2.2 mole percent. The container is useful in packaging beverages and corresponding methods are disclosed.
