A balloon filled standard size balloon with air will last for a week or two, though it will dull and shrink over this period. But a helium filled balloon will only last 12 to 24 hours depending upon the weather. The hotter and higher the humidity the shorter the air time of your balloon. So if you want your balloons to last till late at night please get them inflated later in the day to give yourself the best chance for balloon ceiling all night.
A 90cm jumbo round latex balloon will last approx 36 hours, again dependent on the weather conditions.
Foil balloons filled with helium usually only start to go down after 3-4 days. In the right conditions it might last up to 8 days. It always dependent on their being no leaks and the weather.
We can add a special balloon glue called Hi-Float to the inside of your balloons to make them last up to a week. This glue protects the latex of your balloon from the helium particles and ensures it will float for at least 3 days.
