Multilayered container including a layer of microcrimped metallic foil

摘要

A container is formed with a multilayered wall structure including at least one layer of a plastics material and at least one layer of a multidirectionally microcrimped metallic foil. Initially, the wall structure is in the form of a preform or parison incorporating the multilayered wall structure and the preform is blow-molded to the desired shape. The preform can be blow-molded into a container with a complicated wall configuration. The metallic foil is substantially impervious to the passage of gases, vapor, liquids and microorganisms into or out of the container.
