Latex balloons suitable for air or helium filling.
Filled with helium in a closed environment (18° C) float time is approximately 18 hours.
Filled with air in a closed environment (18° C) endurance is approximately 20 days.
When inflating latex balloons with air or helium we recommend inflating until the balloon has a tear drop shape. Be careful not to under-inflate (round shape) or over-inflate (pear shaped) to achieve maximum flying times.
Latex balloons can be sealed by tying a knot on the balloon neck or by using one of our balloon closures.
These balloons are biodegradable.
