Abstract: A celebratory balloon fabricated from polymeric films have a deposited insularly array of metal which may be further enhanced by polymer encapsulation of the metal. When the balloon is inflated with an admixture of helium and an electronegative gas, the balloon demonstrates to have high breakdown strength across the balloon surface and within the balloon through the inflation gas. The gas mixture further enhances the breakdown strength of the inflation gas by increasing the onset voltage of corona, streamers and spark breakdown. The admixture gas also enhances the breakdown strength of metal-free galloons such as non-metalized balloons, clear balloons, and latex balloons.

Abstract: Formation of an aerostat through the application of a pressure sensitive adhesive onto one or more barrier films at the desired point of bonding between the films. The adhesive is applied about the periphery prior to the point of bonding the two barrier films together. The method of the present invention results in aerostats with a bond line at the edge of the desired shape. The reduced weight, in comparison to conventional practices employing a heat sealing layer, enables intricate designs and smaller volume aerostats.
