Welch Fluorocarbon has produced high-performance bags for NASA for over 15 years.

Aerospace Solutions

Over the years Aerospace engineers have come to Welch Fluorocarbon with problems that have been solved by heat sealing or thermoforming high-performance films.


Aerospace and extreme environments go hand in hand, and Welch Fluorocarbon has been approached on numerous occasions to solve problems due to those environments.


Heat sealed bags and thermoformed three-dimensional parts manufactured from high-performance films (like Teflon® film) have remarkable properties that are extremely useful to the Aerospace industry:

  • High temperature resistance
  • Non-flammable
  • Chemical resistance
