If you’re organizing a celebration or noteworthy occasion and desire to ensure it is memorable, contemplate using mylar balloons. However, how long can mylar balloons endure?

With that, we’ll explore how long mylar balloons can last and examine some factors affecting their longevity. 

So, if you’re wondering how long those colorful mylar balloons can brighten up your party, read on. 

Mylar Balloons: How Long Do They Last?

Depending on the environment and care, mylar balloons can last 3-5 days. 

Mylar balloons can stay inflated for around two weeks if kept away from sharp objects and other indoor hazards. 

If used outdoors, the balloons will typically last a few days, depending on the conditions. 

Find out how long mylar balloons last with helium here.

How To Make It Last Longer?

First, purchase high-quality balloons and check for holes or tears before inflating them. 

Also, use the correct type and amount of helium to inflate the balloons properly. 

The helium should be able to keep the balloons afloat for several days. 

But if you want them to last even longer, you can add a bit of hi-float, a type of balloon treatment, to the helium before you fill the balloons. 

Hence, it will help keep the helium in the balloons for an extended period. 

Plus, avoid placing the balloons in direct sunlight or hot and humid places, which can cause the balloons to deflate quickly. 

Finally, tie the balloons securely with a ribbon or string to ensure they don’t drift away. With these simple tips, you can make your mylar balloons last even longer.

But how can you blow up a mylar balloon?

What Temperature Causes Mylar Balloons To Lose Their Air?

When exposed to temperatures below 50-45°F, the mylar balloons lose their air and can eventually deflate completely. 

The cold temperature causes the helium gas in the balloons to contract and become less buoyant, leading to an overall decrease in air pressure.

But if the temperature goes above 80°F, they can also suffer from air loss. 

 “When one steals a flying balloon and animates it to fly over Paris, one should, ideally, have some idea how said balloon normally works.”

The heat causes the helium gas to expand and become more buoyant, causing the air pressure inside the balloons to increase and can eventually cause them to burst. 

Mylar balloons should be stored in a cool and dark place to avoid this problem. 

Is It Possible To Deflate & Reuse A Mylar Balloon?

Yes, it is possible to deflate and reuse a mylar balloon. If there is no requirement for manually sealing the foil balloon, the balloon can be used more than once.

The mylar material is designed to be durable and can be used multiple times. 

To deflate a mylar balloon [1], you should first find a large needle to puncture the balloon’s surface. 

Carefully push the needle through the surface of the mylar balloon and allow the helium to escape.

When it comes time to reuse the mylar balloon, you must inflate it again. Typically, this can be done using a helium tank, but it can also be filled with air using a pump. 

Once it is filled to the desired size, you can tie it off, and it will be ready to be used again.

How Many Mylar Balloons Can A Tank Of Helium Fill?

A standard helium tank can fill about 16 standard-sized 18-inch or 10-20 inch mylar balloons. 

But if the mylar balloons are larger, such as 12-inch ones, then the number of balloons that can be filled with a tank of helium will be less. 

If the helium pressure increases, more mylar balloons can be filled with the same helium tank. 

Ultimately, the amount of mylar balloons that can be filled with a tank of helium depends on the size of the tank, the size of the balloons, and the pressure of the helium.

FAQs

Can I leave my Mylar balloons overnight in the car?

Leaving your Mylar balloons in the car overnight is not recommended, as extreme temperatures can cause them to lose shape or become brittle.

Which balloons are better: Mylar or latex?

It depends on a person’s preferences, but on most occasions, mylar balloons are the better option. Mylar balloons are more durable and last longer. 

Meanwhile, latex balloons are more affordable and come in various colors, making them an excellent choice for parties or other special occasions.

Are Mylar balloons the same as foil balloons?

Since Mylar is also used as a base material for foil balloons, there are some similarities between the two types. 

Both things are constructed using a particular kind of nylon and have a very thin layer of foil attached to their surfaces.  

What risks are associated with Mylar balloons?

Mylar balloons cause power outages [2] if they come into contact with power lines. And it can be a risk to animals if ingested, as they may cause blockages or suffocation.

Bottom Line

Mylar balloons are a great way to make a special occasion even more special. Not only are they colorful and beautiful, but they can also last for weeks or even months. 

With proper care and handling, they can be a lasting reminder of your special day. 

So the next time you want to add a little sparkle and cheer to your celebration, consider Mylar balloons for a lasting memory.
