Saran Wrap as a Dielectric

[MaverickIce00-at-aol-dot-com (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

List,

    I recently noticed that a roll of Saran Wrap I have is Polyethylene. It's 
probably only a few microns thick (can't find the caliper) but if I used 
enough layers, would it make a suitable dielectric for a capacitor? Would it 
be as good a dielectric as factory-manufactured LDPE? I checked it out, and 
it seems to be pretty clean, no chemicals or anything, but since this is not 
made for such a duty, would it be a bad idea to go ahead and make a cap with 
it? Thanks for your help.
