Overview PTFE tapes are used for heat sealing or roller wrap tapes. Along with good heat resistance, they also possess excellent electrical, mechanical, and chemical properties. PTFE tapes are available with both silicone adhesive or acrylic adhesive backing.

PTFE tapes serve as durable non-stick coverings in heat sealing applications. Packaging materials don't stick to surfaces covered with PTFE tape. The tapes resist high temperatures, and provide a satisfactory rate of heat transfer from the sealing unit to the sealing area on the package.

PTFE tapes help keep plastic films from sticking to hot metal bars and plates primarily used in packaging and welding vinyl windows.
