  • Container with high-crystallinity sidewall and low-crystallinity base
    Patent number: 7445826
    Abstract: A polyester container having an enhanced level of crystallinity in the sidewall while maintaining a low level of crystallinity in a thickened base portion. The container is particularly useful as a refillable container which can withstand higher caustic wash temperatures and exhibits reduced flavor carryover, or as a hot-fill container. The container, which can be monolayer or multilayer, is also useful as a carbonated beverage, O2 or CO2 barrier, or beer container.
    Type: Grant

    Date of Patent: November 4, 2008
    Assignee: Graham Packaging PET Technologies Inc.

  • Method of forming container with high-crystallinity sidewall and low-crystallinity base
    Publication number: 20020150703
    Abstract: A method of making a polyester container having an enhanced level of crystallinity in the sidewall while maintaining a low level of crystallinity in a thickened base portion. The container is particularly useful as a refillable container which can withstand higher caustic wash temperatures and exhibits reduced flavor carryover, or as a hot-fill container. According to the method, a sidewall-forming section of a preform is initially expanded, heated to contract and crystallize the same, and than reexpanded; a base-forming portion of the preform is shielded from the heat treatment and is expanded either before or after the heat treatment step.
