A method for heat-sealing a sheet of heat-resisting polymer to a heat-resisting polymeric fitment, which enables the fabrication of a containment and delivery system for a bulk quantity of meltable adhesive, wherein a rigid container is lined by a heat-resisting flexible envelope, with a heater interposed between them. Ports are sealed to the envelope to permit the filling and draining of molten adhesive.
