摘要:
A multi-layered blown plastic container is formed by injection molding a first thermoplastic parison, axially stretching the first parison at its orientation temperature, injection molding a second thermoplastic parison around the first parison, and blowing the multi-layered parison at its orientation temperature to provide an oriented container, the inner layer being oriented in the axial and hoop directions, and the outer layer oriented in the hoop direction.
