Picture the thrill of a celebration, the happiness, and the lively atmosphere that permeates the surroundings. What heightens this distinct feeling? Of course, it’s the foil helium balloons from Party City.

But as the festivities wind down, you can’t help but wonder: how long do foil helium balloons last from Party City?

As an avid Party City shopper, I’ve put their foil helium balloons to the test. Astonishingly, they’ve soared beyond expectations.

With that, I’ll share my first-hand experiences and reveal how long Party City’s foil helium balloons can last.

How Long Will Party City’s Foil Helium Balloons Last?

Generally, Party City’s foil helium balloons can last around several weeks, depending on the environment and the care taken when handling them. 

Keeping the balloons away from sharp objects, out of direct sunlight [1], and at a consistent temperature can help extend the balloon life. 

Additionally, Party City has a variety of Hi-Float treatments that can be used on the balloons to help them last up to two weeks. 

So, with the right care, Party City’s foil helium balloons can bring a festive atmosphere to any event for days or weeks. But how many balloons do you need to make the balloon arch?

How To Make It Last Longer?

The first step in making Party City helium foil balloons [2] last longer is to fill the balloons with helium shortly before the party. 

It will help keep them from leaking and losing their lift. When filling the balloons, use a quality helium tank and fill the balloons to the recommended size.

Another way to make Party City helium foil balloons last longer is to keep them away from direct sunlight as much as possible. 

The Sun’s heat can cause the helium to expand and escape from the balloon more quickly. Hence, make sure that the balloon is slightly underinflated if it’s the case. 

On the other hand, keep the balloons in a cool, dark environment or slightly over-inflate them until they are ready to be used. 

Also, avoid rubbing the balloons against rough surfaces, which can cause pinholes and leaks.


Do Foil Helium Balloons Lose Air Overnight?

Yes, foil helium balloons are made of a thin, lightweight material prone to deflating over time. 

Since helium is a gas, helium molecules will slowly escape through the thin material of the balloon. 

Additionally, if the balloons are exposed to extreme temperature changes, all balloons will increasingly deflate and pop simultaneously. 

“There is a savor of life and immortality in the substantial fare. Like balloons, we are nothing till filled.”

Herman Melville, American Novelist

For example, if the balloons are in a very cold room, the helium will escape faster, and when it’s exposed to warm weather shortly after, it will pop. 

Moreover, the rate at which foil helium balloons lose air overnight depends on the balloon’s size and quality. 

If the balloon is small and has poor quality, the deflation rate will be worse. But how long do balloons that are filled with air last outside?

How To Prevent A Helium Balloon From Deflating?

One should ensure the balloons are properly inflated and sealed to prevent foil balloons from deflating. 

This process should be done carefully with a balloon pump, and the nozzle should be inspected for any signs of damage or wear. 

You should also avoid overfilling the balloon, as doing so can lead to seam tearing and the balloon deflating. 

Another way to prevent foil balloons from deflating is to use a helium tank when inflating them. 

Helium is less likely to leak than air and has a much longer lifespan in balloons than air. 

Also, helium tanks often come with a regulator, which helps ensure the balloons are not overfilled. Learn more about the tips to make air-filled balloons last longer here.

Are Foil Helium Balloons Reusable?

Yes, they can be. Foil helium balloons can be filled with helium multiple times and reused. 

The key to reusing them is ensuring the balloons are completely deflated before replacing them with helium. 

To do this, you can allow the helium to escape from the balloon by pressing the nozzle and gently deflating it until it is empty. 

Then, fill the balloon with helium again and seal the nozzle. This process can be repeated multiple times, depending on the strength of the balloon.

Can foil helium balloons be inflated twice?

Yes, foil helium balloons can be inflated twice. The second inflation, however, must be done with care so as not to overfill the balloon.

But how many balloons can a helium tank actually fill?

Can foil balloons be inflated the evening before the party?

Yes, it can be inflated in the evening, so the balloons need time to deflate before the celebration begins.

But can you build a balloon arch the night before your party?

What kind of spray to put on balloons to make them stay longer?

Spraying balloons with a silicone-based product or hair spray can help them to last longer. 

And helium-filled balloons with a light mist of water or a balloon shine product can also help them stay afloat for longer.

Final Thoughts

Overall, foil helium balloons from Party City can last around a few days to weeks, depending on the type of balloon, the quality of the helium, the environment, and other factors. 

By taking proper care of the balloons and ensuring that they are properly filled with quality helium, you can ensure that your balloons last for as long as possible.
