METHOD FOR MAKING A MULTI-LAYER BLOW MOLDED CONTAINER

摘要

A method for making a multi-layer blow molded container (10) is performed by providing a sheet (34) of virgin polyethylene terephthalate with a pattern of barrier layer spots (36) prior to thermoforming at each barrier layer spot to provide a preform liner (24) about which polyethylene terephthalate (26) is injection molded to provide a multi-layer preform (10') from which the container is blow molded.
