ABSTRACT:
Apparatus for manufacturing heat sealed products from high temperature film materials exhibiting superior barrier properties, such as films made from LCP resin. The apparatus has in relevant part a first compression member having a heating element that is capable of being continuously or intermittently heated to a temperature of about 300.degree. C. (c. 575.degree. F.) backed by a layer of material capable of supporting the heating element, a second compression member that opposes the first compression member and having an electrically conductive tubular sealing element, capable of being flash-heated by means of a pulse of electric current to a temperature of about 425.degree. C. (c. 800.degree. F.) and immediately flash-cooled to room temperature or below by means of forcing vortex-chilled coolant fluid through the tubular lumen, backed by a layer of material capable of supporting the sealing element, and two floating sheets or tapes of high-temperature release material disposed therebetween.
