London Helium Balloons adheres to EBPC Code of Best Practice

Longevity of Balloons and allergy considerations
Foil balloons typically last longer than latex balloons, which unless specially treated will only stay floating for 12 hours max.  Latex balloons can be specially treated which means they will last up to 3 days as opposed to 12 hours.

Latex balloons can be used in balloon releases but curling ribbon must not be attached to the balloon as it causes environmental problems.

Foil balloons are a good choice for children’s parties particularly when you know or are unsure if one of your guests suffers from a latex allergy.

Foil balloons must always be attached to a weight and must never be released into the atmosphere as they can cause great harm to the environment. Foil balloons will never have metallic curling ribbon attached as this can cause a hazard.

Helium is sensitive to heat as it will expand in heat and contract in the cold, we inflate the balloons in a median temperature to minimise problems but be aware on occasion the balloons may seem to contract, when placed in a warmer room they will expand back to normal again, this is more evident with foil balloons than with latex balloons.
