You are 100% wrong!
PET is polyethylene terephthalate
whereas,
MYLAR is Polyester film and it is hard
it cracks and tears when when a sharp
slit forms from a blade cut.

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.
