Important Information on Airfill Balloons
Mylar/Foil Balloons 14" and under are considered airfill balloons.  They do not float with helium and require heat sealing.  This is the same across all manufacturers of foil balloons.  An airfill balloon is typically displayed on a stick.

Why don't foil balloons 14" and under float with helium?

They will not float because the amount of helium held in the balloon is not enough to overcome the actual weight of the foil balloon.  If you want a foil balloon to float the standard size helium foil balloon is 18".

Why do foil balloons 14" and under require heat sealing and what is it?

Unlike foil balloons 18" and larger balloons 14" and smaller do not have self sealing valves inside.  This is not unique to our balloon manufacturers  This is the same for all manufacturers of foil balloons.  Because there is no self sealing valve inside the air can escape from the tail of the balloon.  Heat sealing is essentially the melting of the two sides of the tail of the balloon together to make a seal.  A demonstration using a bag is shown to the right.

If you do not own a heat sealer (impulse sealer) you can alternatively use a flat iron hair straighter or curling iron on the medium setting. Cover the ends of the hair straighter with aluminium foil to avoid damaging it.  Fill the balloon with room temperature or cooler air (not with your mouth) using a bike pump etc.. and then seal the end using the heat sealer or hair straighter.  One suggestion is to twist and tie the balloon tail first and then seal it after.  Tying it will stop most of the airflow, but not all of it.  Heat seal it as well since this will better guarantee a complete seal.  The knot may interfere with you putting the balloon on the balloon cup

This will take a little practice so we suggest buying a few additional balloons. 

Impulse sealers can be bought on Ebay and other websites for $20.00-$50.00.  Therefore if you are looking at getting into the business of selling airfill balloons then it is best to invest in the correct equipment.

Do foil balloons 14" and under require cups and sticks?

 It is not a requirement to purchase cups and sticks for your airfill balloons, but since the balloons will not float they are typically put on sticks and displayed that way.  We sell one piece sticks that are both the cup and stick together and sticks and cups separate so you may choose.  Many people prefer the two piece cup and sticks since they feel they hold the balloons upright better.
