초록

A multi-layer preform used for plastic blow molding and a method for making the preform provides an inner layer of polyethylene naphthalate and an injection molded outer layer of homopolymeric polyethylene terephthalate which has reduced transmission of gas upon blow molding as a container due to the gas barrier provided by the inner layer of polyethylene naphthalate. The inner layer of homopolymeric polyethylene naphthalate by itself or along with a further inner layer of virgin polyethylene terephthalate is thermoformed prior to the injection molding o...

청구항

[ What is claimed is:] [1.] A multi-layer preform used for plastic blow molding, comprising:an inner layer consisting essentially of homopolymeric polyethlene naphthalate for providing a gas barrier; andan injection molded outer layer of polyethlene terephthalate which defines an outer surface of the preform and, upon blow molding of the preform into a container, gas being transmitted through the container to an extent limited by the gas barrier provided by the inner layer of polyethylene naphthalate.
