I am thinking about using 3 sheets of 30 mil poly to make a 90 mil sheet
Thanks for the reply I like to double check before starting in on a project like this. one miscalculation and a lot of money and time down the drain.

Gary,

If you're shooting for around 0.005 - 0.006 uF it's about right. Also,
use multiple sheets of LDPE rather than a single sheet to prevent
premature failures due to any defects in the material.
