ABSTRACT:
A structural, informative and/or decorative balloon display is comprised of a plurality of connected, inflatable chambers formed by a plurality of die applications to a plurality of layers of film. The largest die application produces a set of seals that encompasses an area smaller than the area encompassed by all such sets of seals. In one preferred embodiment connected chambers have and maintain fluid communication. In another preferred embodiment, connected, inflatable chambers have no fluid communication but have a beginning and an end. In other preferred embodiments fluid communication is terminated after inflation. Other embodiments take advantage of variations of numbers of layers, configurations of layers, and treatment of surfaces to create special balloon forms.
