ABSTRACT:
An improved PET process, system and container which uses an improved single stage process to produce a thermally stable container. The single stage process arrests the cooling of the preform at elevated temperatures followed by equilibriation to a set temperature in a conditioning station at controlled time rates to achieve high crystallinity in the container side wall. Special provisions are made for establishing a transition zone temperature gradient adjacent the container mouth to achieve high crystallization in the transition zone. The container is especially configured in a number of instances to make it suitable for hot fill applications. One such instance includes rigidizing the body side wall against radial and longitudinal vacuum distortion so that paper labels can be applied to the container.
