beware! There may be some confusion between;
PETG-Glycol modified polyethylene terephthalate (a.k.a. copolyester)  and
Polyethylene Terephthalate (biaxially oriented no less!) a.k.a. Mylar.
these are related materials to be sure 
and I suspect that the electrical properties are similar,but....( my
electrical data on the petg is vague).  as an aside many bottles have high
recycle content (always bad)
