New foil material
Foil balloons of a new material have been introduced 1-3 years ago: the foil comes within a (humid) bag. Having broken this bag one should inflate the balloon pretty soon - some minutes I think. The foil expands somewhat, which means, that (nearly) no wrinkles a produced near the seams like ordinary PA- or PES-foil balloons. The inflated balloon dries (from water, alcohol?) and gets stiffer then. I have only read about it. --Helium4 (talk) 12:40, 25 April 2014 (UTC)
