1. A method of creating a non-conductive film for lighter than air balloons, consisting of:
providing a gas barrier core;
applying a patterned metal layer to the gas barrier core; and
applying a heat sealing layer to the gas barrier core to form a non-conductive film;
wherein the gas barrier core consists of a set of gas barrier layers and a layer comprising Ethylene vinyl alcohol (EVOH) sandwiched between a first adhesive layer and a second adhesive layer.
