No doubt Googglabet knows.

I've not played much in this area for some while.

A whiff of Nickel spray  (sold for shielding) works for plastic boxes - and
no doubt for bags if you don't mind the appearance  - and a can goes a long
way.

Butyl Rubber sold for roofing is cheap compared to ESD mats.
Even cheaper (far cheaper) are the just-as-effective cover sheets they pack
the bales in.
