    摘要: The process selectively crystallizes a molecularly oriented thermoplastic container (20) composed of portions thereof (23,24,25,26) with different degrees of orientation. Portions of the container (24,25) are heat treated at temperatures suitable to crystallize said portions according to the degrees of orientation thereof wherein the heat treatment takes place in a heating environment on an unconfined container. The selectively crystallized container is then sized in a finishing means.
