Last Updated on April 26, 2023 by Kimberlee Johnson

Do you want to add a festive touch to any occasion? Foil balloons are the perfect way to decorate for any event and make it extra special. 

Plus, they look amazing when filled with helium. But how do you blow up foil balloons with helium? Don’t worry; we’ve got you covered. 

Our team will show you exactly how to blow up foil balloons with helium so you can easily achieve amazing results every time. Read on. 

5 Steps In Filling Up Foil Balloons With Helium 

Filling Helium on a foil balloons
  1. Gather all the necessary supplies, such as helium tanks, foil balloons, and a helium regulator.
  2. Attach the helium regulator to the end of a balloon. Make sure that the valve is closed and the regulator is off. Then, connect the helium tank [1] to the regulator and open the valve. 
  3. Turn the regulator to the on position and allow the helium to fill the balloon.
  4. Inflate the foil balloons to the desired size and tie a knot at the end of each balloon. 
  5. Once the balloon is filled to the desired size, tie a knot at the end to keep the helium from escaping and repeat the process for the remaining balloons.

Can You Inflate Foil Balloons Manually?

Yes, it is possible to inflate foil balloons manually. Foil balloons have a self-sealing valve, making them easy to fill with air using a manual pump. 

But you can use other methods to inflate balloons using the mouth [2] or straw. 

The process of inflating foil balloons manually is fairly simple. First, attach the pump’s nozzle to the valve on the balloon and start pumping air into the balloon. 

Make sure to pump slowly and steadily; otherwise, you will over-inflate the balloon and cause it to burst. Once the balloon is full, it should look round and firm.

When inflating foil balloons manually, it is important to take safety precautions. In addition, keep the pump away from children and pets, as it can cause injuries.

Can Foil Balloons Float Without Helium?

 Yes. Foil balloons are made of a durable, lightweight material that makes them buoyant, even when filled with air instead of helium. 

They are less likely to become deflated and stay inflated for days or weeks. 

“You lose your anonymity just like a helium balloon with a string. Therefore people are going to have their own opinion and they’re going to write in whatever clever manner they desire.”

But when using foil balloons without helium, it is important to know that they will not reach the same heights that helium-filled balloons can. 

The balloons will still float, but they will not be able to reach the same height as those filled with helium. 

Additionally, note that foil balloons can be heavier than latex balloons, so they will not rise as quickly. But how can you blow up a mylar balloon?

How Long Does Helium In Foil Balloons Last?

Helium-filled balloons can last around 7-10 days, depending on the quality of the balloons, the temperature, and the environment in which the balloons are kept. 

Helium is a gas, so it is affected by temperature and pressure. 

When the pressure and temperature drop, the gas inside the balloons expands, and the balloons become larger and lighter. 

It can cause the balloons to float away, so they should be kept indoors and away from open windows. 

When the helium-filled balloons are kept in a cool and dry environment, they usually last up to a week or two. But how long do foil balloons usually last?

What Can You Use To Fill Balloons If You Don’t Have Helium?

One of the easiest and most accessible methods is to use a simple straw to blow the balloons up. 

Start by inserting the straw into the balloon’s opening, then blow into the straw as if you were blowing up a balloon with your mouth. 

Eventually, it will take some effort to fill the balloon with air. You can also use a small electric or hand-held air pump to fill the balloon quickly. 

This method is often used for bigger balloons or large batches of balloons. Another option is to use a device called a balloon inflator. 

This device pumps air and water into the balloon quickly and efficiently. It’s a great option if you have access to a hose but it requires a bit of setup and setup time. 

But you can also use other gas to fill the balloons and make them float. The most common gas used to fill balloons is air. 

You can use a hand or electric pump to blow the balloons up, and they will stay afloat for a few hours, depending on the size of the balloon and the amount of air put into it.



Do helium balloons last longer if you spray them with hairspray?

Spraying helium balloons with hairspray can help extend their float time as the hairspray helps to slow down the rate of helium leakage. 

Hairspray also helps to reduce the chance of the balloon popping due to friction, which can help keep it afloat for longer.

Will helium foil balloons last throughout the night?

Yes, helium foil balloons will last throughout the night as long as they are filled with helium and tied securely to an anchor. 

Helium foil balloons typically last 8-12 hours, so they are perfect for any evening celebration. Find out how long helium balloons can stay inflated here.

Why won’t some balloons float when filled with helium?

Helium-filled balloons may not float if they are too heavy or if they have been overfilled with helium.

Additionally, some balloon materials are not conducive to helium and may not float even when adequately filled with helium.

Final Thoughts

Foil balloons are a great way to add a touch of flair to any event, and with the help of helium, you can easily make them last for days. 

Now that you know how to blow up foil balloons with helium, all that’s left to do is pick out the perfect design and have a blast.
