How long will helium latex balloons float?
We chemically treat our balloons with a concoction of goop with allows them to float about 4-5 days. Without this treatment, they last maybe 6 measly hours. We always treat our balloons because we want to give you maximum value and enjoyment for your money. You didn’t ask, but mylar (also called foil) balloons can float for weeks. I know because have one I can’t reach on my ceiling right now that I inflated about three months ago.
