FLOAT TIMES OF HELIUM FILLED BALLOONS
There are many different factors that affect the float time of a helium filled balloon; microfoil and bubble balloons have a longer float time than latex balloons, also the size of the balloon (generally, the bigger the balloon, the longer it lasts). In addition, the temperature and conditions that the balloon is kept in will impact upon the length of time that it remains floating (see our caring for your balloon page).
Wherever possible, we treat our latex balloons with a non-toxic sealant which coats the inner wall of the balloon. The sealant helps to stop the helium molecules escaping so quickly through the wall of the balloon and therefore significantly increases the balloon’s float time. The average float time for a treated 11 inch latex balloon is around three days. If untreated, a latex balloon of this size will only float for sixteen-eighteen hours. The larger 16-inch round balloons (that we use for ‘double bubbles’) last approximately two days and the 3-foot giant latex balloons around three to four days.
However, it is important to be aware that the balloons will get smaller with each passing day, as they gradually lose helium. When ordering latex balloons we therefore strongly recommend that they are delivered (or collected) on the day of your event to ensure that they look their best for your celebrations.
FLOAT TIMES FOR FOIL BALLOONS
In optimum environments, foil balloons will remain full and taught for three-five days. They will usually continue to float for longer but will appear less taught as they start to lose helium. Cool air may cause these balloons to shrivel, but they will return to a normal state when exposed to warmer air.
FLOAT TIMES FOR BUBBLE BALLOONS
Bubble balloons will remain full and taught for several days and are likely to continue to float for two weeks or longer.
Please note; all of the float times detailed above are average float times and apply to balloon-friendly indoor environments. They are not a guarantee and are to be used as a guide only. Actual float times will vary depending on temperature and atmospheric conditions.
