Last Updated on September 25, 2023 by Kimberlee Johnson

Do you want to make your party extraordinary? Mylar balloons are the perfect way to do just that.

They are easy to inflate and come in various shapes and sizes, perfect for any occasion. As such, we’ll teach you how to blow up a mylar balloon in just a few simple steps. 

With the right supplies and a bit of practice, you’ll be ready to make your party or event stand out in no time. So, let’s get started.

9 Easy Steps To Blow Up A Mylar Balloon

1. Start by finding a flat surface to work on. It’s best to avoid sharp or pointed objects that could puncture the balloon.

2. Unfold the mylar balloon and locate the inflation valve. This is usually a small, round opening on the bottom of the balloon.

3. Attach the nozzle to the inflation valve if you have a balloon pump. If you’re using a helium tank, attach the valve to the inflation valve instead.

4. Hold the balloon by the bottom or neck, depending on your preference.

5. Inflate the balloon slowly and steadily, careful not to overinflate it. If you’re using a balloon pump, use short, quick bursts of air to avoid overinflating the balloon. 

If you’re using a helium tank, release the helium slowly and stop when the balloon feels full.

6. Check the balloon’s firmness by gently squeezing it. If it feels too soft, you may need to add more air. If it feels too firm, release air until it feels just right.

7. Remove the nozzle or valve from the inflation valve once the balloon is fully inflated.

8. Tie a knot in the neck of the balloon to seal it. Attach a string or ribbon to the knot if you plan to hang the balloon.

9. Adjust the balloon’s position by gently pulling or pushing it until it sits at the desired angle. But how do you blow up foil balloons with helium?

A hand pump is typically a cylinder-shaped object with a nozzle at one end and a handle at the other. 

“There are times in life when people must know when not to let go. Balloons are designed to teach small children this.”

– Terry Pratchett, English Humorist

This inflation method is relatively quick and easy, allowing you to easily adjust the air you want in the balloon.

4. Electric Balloon Inflator

An electric balloon inflator is another option if you have a lot of balloons to inflate. These can be purchased online or at party supply stores.

How Long Will An Air-Filled Mylar Balloon Remain Inflated?

Mylar balloons can remain inflated with air for up to two weeks, depending on the size and quality of the balloon. 

Some smaller balloons may only stay inflated for a few days, while larger balloons may stay inflated for up to a week or more. 

In general, however, you should expect the balloon to remain fully inflated for three to five days. 

Mylar is a robust and durable material that is resistant to punctures, so it can keep the air in the balloon longer than other materials.
