Abstract

A heated container is formed from a substantially continuous element structure. The substantially continuous element structure includes an electrically insulative first and second polymeric layers and a resistance heating layer laminated between the first and second polymeric layers. An interior surface of the container includes the first polymeric layer, and the first polymeric layer is thermally conductive. The resistance heating layer has a pair of terminal end portions that may be coupled to a pair of external power leads to energize the resistance heating layer.
