Saran Wrap is Polyvinylidene Chloride, and its dielectric constant is
between 4.88 (60 Hz) and 3.18 (1 MHz), so using 4.0 is not a bad
estimate at TC frequencies. At 1 MHz, it's over 700 times as lossy as
LDPE, so it's a rather lossy dielectric if you're thinking about using
it as a capacitor dielectric...
