Abstract

A method for producing a heat set plastic container including: providing a mold cavity having sidewall surfaces and base surfaces; providing a plastic preform within the mold cavity; expanding and stretching the preform into conformity with the sidewall surfaces and the base surfaces to form a plastic container having a sidewall and a base; and inducing crystallinity in the base of the plastic container by applying heat from the base surfaces of the mold cavity to the base of the plastic container and by applying heat from an interior portion of the plastic container to an interior surface of the base of the plastic container.
