How Long Can A Filled Helium Balloon Last?

- Oct 12, 2018 -

How long does a filled helium balloon last? A 10-inch helium balloon (one inch refers to one inch, one inch is equivalent to a diameter of 2.54 cm, and a 10-inch helium balloon is about 25 cm in diameter). Generally speaking, a 10-inch helium balloon lasts for about 5 hours. Of course, the holding time is uncertain. If the helium balloon is kept in a lower temperature environment, the time is longer, such as an air-conditioned room. Generally it can be kept for 7 hours, which depends on the temperature.

Special attention should be paid to outdoor use: Please avoid sun exposure before the event begins. After the sun shines, the balloon will be dull, that is, the "oxidation" is affected by the temperature, and the life of the helium balloon is greatly reduced. If you can't avoid direct sunlight when using a helium balloon, pay special attention to the helium balloon in a sunny environment. Generally, it can only last for 4 hours. If it is summer, the light is strong, and it is difficult to maintain it for 4 hours. Therefore, we must pay attention to the budget time when doing activities. Therefore, the small partners should pay attention to how long the helium balloon can be kept and the temperature is closely related.

How many balloons does a large bottle of helium charge? This depends on the diameter of your balloon! We have 40L and 8L in the balloon.

(1) 40L bottled helium: 10 inch balloons can charge 600-650, 18-inch about 200-300;

(2) 8L bottled helium: 10 inch balloons can charge 60-100

Of course, there is also an important factor that the correct operation of the helium balloon will affect the number of the last helium balloon!
