Heat Sealing of thin fluoropolymer films (such as Teflon™)

We have been heat sealing thin fluoropolymer films, like Teflon™, since 1985.  If it is a thin high performance polymer and it can be heat sealed, we’ll heat seal it!   We can produce a wide array of lay-flat and three-dimensional configurations utilizing our existing technologies.    

Advantages of Heat Sealed Products made from fluoropolymers such as Teflon™:

  • Chemical Inertness
  • Chemical Resistance
  • High Temperature Resistance
  • Cryogenic Temperature Resistance
  • Low Permeability
  • High Weatherbility
  • Excellent Optical Clarity
  • Releaseability
  • High Dielectric Strength
  • Low Flammability


Examples of Heat Sealed Fluoropolymer (Teflon™) Products:

  • Bags for inert sampling
  • Cryogenically resistant bags
  • Large panels or continuous belts
  • Highly temperature resistant bags
  • Cell culture bags
  • Reservoir bags to hold caustic fluids
  • Liners for a variety of containers like pails, drums or tanks
  • Fluid transfer bags with Fluoropolymer fittings heat-sealed into them
  • Three dimensional Simulation Chambers used for aerosol experiments

Processes

Our heat sealing manufacturing processes allow for a wide array of applications, and if required can be tailored to a specific need. All heat sealing processes are highly traceable, and Certificates of Compliance are available upon request.

Materials

Working with fluoropolymers (like Teflon™) is our specialty, but we are able to successfully heat seal a variety of high-performance thermoplastic films including:

  • Teflon™ FEP
  • Teflon™ PFA
  • MFA
  • MPTFE
  • PVDF
  • ETFE
  • PVF
