How long do mylar balloons stay firmly inflated?

by Marc
(Modesto, Ca)

Can a mylar balloon stay firmly inflated for years, or is its life much shorter? THIS APPEARS TO BE A NON- HELIUM BALLOON.
Thanks,
Marc

I have a Christening Mylar Balloon that looks like it was just inflated from 9 years ago....very firm!! I won't move it from it's spot for fear, it will go down. I thought it was just mine...glad to see there are others out there.

Have Mylar balloons changed? Here in 2017-2019 timeframe we have refilled our Mylar balloon every year and it only lasts for a couple months. Maybe a 30 year Mylar balloon wasn’t good for return business?

Mylar balloons NEW
by: Bjharrison

This story is for the history books. This is 30 yrs old and the Mylar balloons are still up!!!When my daughter was born on 10/10/1988 my son got this arrangement for me that was in a hat type container with more ribbon. Over the years the container fell apart but the Mylar balloons stayed up. They have been thru over 15 moves and 3 states. They are now beginning to show their age so before they decide its time to go down I wanted to share their story... never would I have thought these Mylar balloons would still be up 30 yrs later!!!!!

I thought we were the only ones to have a balloon stay inflated for this long. But glad to know it should stay inflated for many more years.

The "It's a Boy!" mylar balloon (on a stick) we received at the birth of our son 28+ years ago is just as plump as it was in 1988! For years it was in the closet, then I realized this special balloon has become a family treasure and merits a place of honor. Now it's displayed in our glass-front cabinet where it's protected from mishaps and dust. I'm AMAZED it's still in perfect condition!

11 Years and Counting

My dad (RIP) bought my daughter one when she was born 11 years ago and I still have it. (It's fully inflated). I have never heard that balloons can do this and I was slightly disappointed that others have the same experience. I know that sounds weird but it was something inside me that made me feel as if this was him showing us he was around....... :-(

I got one when my son was born 27 years ago. It is still inflated. The stick came out years ago so it was put in a 1 gallon ice cream bucket where it remains until it comes out each year to have his birthday picture taken. Still counting.

Air Filled Mylar Balloons
by: Margit

Hi Marc,

I have heard of cases where a helium filled mylar balloon stayed up for more than 2 months: http://bastone.org/blog/?p=288.

So an air filled foil balloon will definitely stay inflated for longer.

But whether they would stay firmly inflated for years, I can't tell you. I doubt it though, as they will lose some air through the opening where you inflate them.

Hope that helps,
Margit
