ABSTRACT:
An improved plastic bag sealing apparatus comprised of an improved resilient planar heater formed of a heating wire embedded in a resilient silicon rubber material. The heater is shaped to conform to the flat planar surface of a T-bar shaped heating element, and clamped in place with insulators to provide maximum transfer of heat to a heating edge formed by the web portion of the T-bar. In an optional configuration the heater is in the form of a tubular rod seated in a channel in the T-bar directly above the heating edge for transferring maximum heat to the heating edge. The containment of heat and transfer of maximum heat to the T-bar permits a substantial improvement in thermal efficiency and a substantial reduction of power consumption. The heating edge of the T-bar is covered with an easily replaceable heating channel coated with a non-stick, heat resistant material such as polytetraflouroethylene (TEFLON).
