Heat Sealing Teflon® Film & Other High Performance Thin Films

Heat sealing is the thermal fusion of two (or more) melt-bond compatible thermoplastic materials. All heat seals require the precise control of heat, time, and pressure to create a quality weld. Thermal Impulse heat sealing is the process of welding thermoplastic films together by means of a resistance ribbon(s) through a cycle of heating and cooling under pressure. By controlling the rate of heating and cooling superior welds are created without sacrificing the physical property values of the original film. Thermal impulse techniques are used to make bags, lay flat tubing, medical packaging, large panels, protective garments, heat exchangers, geodesic domes, and other unique shapes that solve specific problems.
