The inner face is plasticized with a polyethylene to allow a heat seal. It is then cut into a balloon shape and heat welded around. Thanks to their composition, foil balloons are less porous than latex balloons and therefore remain inflated much longer. They are not Biodegradable. As a professional artist there are rules to follow when using foil balloons. These rules are better known as: "The Californian Law": -Foil balloons inflated with helium must be ballasted individually to prevent them from flying off. - Foil Balloons should not be tied together when in a bunch of helium-filled balloons. - Never attach wire or metal tape to foil balloons inflated with helium. These rules are justified by the fact that the foil balloons are not biodegradable and that their metal surface makes them conductive, which could create problems if they meet power lines.
