摘要 |
<p>A multi-layer preform having at least one foamed layer suitable for forming a multi-layer blow molded container having at least one foamed layer container is disclosed, the multi-layer container formed by a process comprising the steps of injection molding a polymer melt having a non-reactive gas entrained therein, causing entrained gas cells in the polymer melt to open to form a polymer preform having an open cell foam layer, cooling the preform to a temperature below the polymer softening temperature, reheating the preform to a temperature greater than the polymer softening temperature, and blow molding the preform in a second mold, to prepare the container. At least one layer of the container may be blended with an oxygen and/or carbon dioxide barrier material.</p> |
