Abstract

A heater comprising: (a) a resistive substrate that produces heat upon an application of power; (b) a substrate adhesive including a portion that extends into the resistive substrate and a portion that extends from one or more sides of the resistive substrate so that one side of the resistive substrate is free of the substrate adhesive and one or more sides is covered by a layer of the substrate adhesive; (c) one or more power application portions connected to the resistive substrate on the side of the resistive substrate that is free of the substrate adhesive; (d) one or more attachment devices that connect the one or more power application portions to the resistive substrate; (e) a closing layer including: (i) a closing backing and (ii) a backing adhesive that includes a portion that extends into the closing backing and a portion that extends from one or more sides of the closing backing so that one side of the closing backing is free of the backing adhesive and one or more sides is covered by a layer of the backing adhesive; and wherein the closing layer extends over the one or more power application portions so that the backing adhesive covers the one or more power application portions, and wherein the substrate adhesive and the backing adhesive extend together to form a single layer of adhesive.
