"One of the main reasons we chose Castle Balloons was because of their biodegradable materials, however I was impressed by not only their sustainability commitments but also their creativity and enthusiasm in helping us create the perfect display for our corporate summer event. They took the time to understand exactly what we wanted and created the perfect display, taking onboard our brand guidelines and preferences in the design."

Who We Work For



The rubber latex balloons used by Castle Balloons, are plastic free and will biodegrade.

Natural rubber latex is collected from Hevea Brasiliensis Pará rubber trees to make all rubber balloons. Rubber latex begins to decompose as soon as it is manufactured and comes into contact with natural elements. When the balloon is inflated and exposed to natural sunlight and oxygen, decomposition is accelerated.
