Helium Latex when filled with helium, an 11-inch latex balloon will generally float for
between 6-8 hours, then begin to ‘haze’ and deflate.
Hi-floated 11-inch latex balloon typically last for 24-36 hours. HI-FLOAT contains a water-
soluble plastic, which dries inside the balloon to form a coating which helps to retain the
Helium-filled foil balloons can last for days.
Air-filled latex balloons do not float, however, they have the advantage of generally having a
longer life than helium-filled balloons. Air-filled balloons can last several days, even weeks,
in the right conditions.
Warning - If you'll be using balloons for an event, use conservative estimates for their
inflation time, and wait as long as possible before the start of the event before inflating the
balloons. That way, you'll be sure not to have droopy decorations at the end of the party.
Cold air, hot air, high humidity, changing barometric pressure, high altitudes, and moving air
from fans and vents will reduce balloon float times. The float times posted on our site are
the maximum to be expected. Changing conditions mean that on some occasions balloons
may float for only one day, and on other occasions the same balloons may float for many
days. We guarantee that your balloons will be delivered in perfect condition, but float times
are not guaranteed.
