Non-flammable, non-explosive
All balloons we supply can be filled with helium gas. Helium gas is a natural noble gas that is non-flammable, non-explosive, and non-toxic, and is a component of our atmosphere. Authorized gas suppliers are happy to assist you with its delivery and usually provide a filling valve to make it easier to fill balloons yourself.
Floating time
Since helium is extremely volatile, its shelf life is limited compared to balloons filled with air. A maximum of 12 hours for the 85/95 balloon size. Therefore, balloons filled with helium gas float for only a few hours (depending heavily on the chosen balloon size).
Filling Method
The filling method is also extremely important: never fill a helium balloon to 100% capacity; approximately 80% of the balloon’s actual volume is sufficient. Since a balloon can rise to many thousands of meters in altitude, it will expand in the atmosphere and thus have sufficient “space” to expand, making the chance of floating far greater than with a 100% filled balloon. Also, never add air to the balloon filling (to potentially save money), as this does not benefit the balloon’s lift. Giant balloons, on the other hand, have a significantly larger capacity compared to normal balloons and therefore remain aloft much longer.
Recommendation:
We recommend a minimum balloon size of 85/95 cm for helium filling
Balloon Decorations
We recommend filling the balloons as close to use as possible. If you fill balloons with helium today, they will definitely be on the ground tomorrow! However, this has nothing to do with quality, as they remain inflated for weeks when filled with air. Helium escapes through the pores of natural latex.
DO NOT RELEASE THEM!
Wisa Enschede does not endorse releasing balloons. Our advice is not to release helium-filled balloons to prevent environmental pollution and to ensure they do not end up in the atmosphere (however, releasing balloons is not prohibited by national law).
Helium gas is available exclusively at locally authorized gas depots.
