I have three questions conerning capacitors..

First, the Polyethaline rolls bought from hardware stores, does anyone by anychance know the purity on this?

I was also wondering, lets say i need 10 layers of 4 mill polyethaline.
Can I assume that (affter compression) the distence is 40 mill? or do I need to account for some distence betweend the layers? (so that it is large than 40 mill)

lastly, I know the plates have to be smaller (width and hight wise) than dielectric between them, so their is no flash-over. What should this be? about one inch wider and taller (so .5 inch boarder)?
