โMylar Balloonsโ
Are Mylar Balloons made of DuraLar? No! Mylar Balloons are not made of any type ofย DuraLar, or Mylar or any other type of Polyester Film. ” Mylar balloons ” are made of a specially coated Nylon designed to seal to itself, and act as a barrier to hold helium gas. Unfortunately, we do not supply any material that is acceptable for this application. ย Any film that we would sell you, would not be able to hold the helium gas long enough to make it worth while!
