Mylar Balloons in Balloons(1000+)

How long will a mylar balloon stay inflated?

Mylar balloons can stay fully inflated for up to five days and will continue to float for around two weeks. Air conditioning or cold rooms can cause a mylar balloon to shrivel, but it will expand again when exposed to warmer air.

Can I fill a mylar balloon with regular air?

Yes, you can fill a mylar balloon with regular air, but keep in mind that it won't float unless it's filled with helium. Mylar balloons filled with regular air can be attached to the wall or on a garland and will stay inflated until they are deflated or punctured.

Can I reuse a mylar balloon?

Most mylar balloons that are over 16 inches are self-sealing, which means they can be deflated and used again at a future date. Smaller mylar balloons tend to be manually sealed, which means they can't be deflated for future use.
