The usual nylon/polyethylene coextruded/laminated metalized film used for the mini-blimps and larger foil balloons would give a 36" spherical balloon weight of 84 grams. This is the film that I understand Ray used. There are thinner such films available. FYI, the typical "Mylar" heat blanket (which is usually not Mylar but PET film) would give a 45g 36" balloon (not including the glue as this material is more difficult to heat seal). The typical 36" latex balloon we use weighs just over 30g and about 40g with the typical fill valve and plug.
