Mylar Balloons (also called Foil Balloons) are a fun addition to your party decorations, especially if you are planning a themed party. Mylar balloons in your child's favorite character, like Elmo or Cinderella, or animal-shaped balloons for a Jungle party really add to the atmosphere. Mylar balloons are also available in letters and numbers so you can customize a message and hang the balloons as a banner. There are so many new styles of foil balloons. We guarantee kids love them but so do adults! Many people have questions on how exactly to inflate Mylar balloons. Follow the instructions below and enjoy your party stress-free!  


What You Will Need
  • Helium Tank or Balloon Pump
  • Ribbon
  • Balloon Weight
Instructions There is a small valve or opening in the "tail" of the balloon. Slide this opening onto the nozzle of the helium tank or balloon pump until you have a tight fit. Hold the neck of the balloon firmly around the nozzle with one hand and press on the nozzle to release the helium into your balloon. Use the hand pump if you don't need your balloons to float. Inflate the balloon. Mylar (foil) balloons are self sealing, so just remove the nozzle from the balloon and press the valve flat to seal. Tie the ribbon to a balloon weight to prevent the balloon from floating away. Or hang the balloon on a wall or garland.  
  Balloon Tips:
  • A foil balloon can appear deflated in cold air, but it will fill out when warmed up.
  • Do not expose foil balloons to extreme heat or they can burst.
