Abstract

A retortable container (C) or a retortable closure (10) for use with the container (C). A receptacle (R) is included that may incorporate fasteners (F) attaching the closure (10). The closure (10) includes a retainer (20) received with a sealing barrier (100) formed from a polymeric material. The sealing barrier (100) includes a heat transfer material such as powdered metal in a volume that is between about 25% and about 65% of the closure (10) and an an oxygen barrier material such as a nanocompound or other barrier material having a relative volume of approximately between 10% and 60%. Variations of the closure (10) may incorporate seal layer of a thermoplastic elastomeric vulcanizate such as a santoprene and the heat transfer material may be an economically attractive powdered and / or oxide material such as zinc, aluminum, copper, nanotube, or similarly available material, which preferably is diffused throughout the closure (10).
