I've taught about methods of protection against humans charged with static electricity, and now I've an example in my hands. My synthetic layers often produce sparks and the voltage would exceed the breakdown voltage of the diodes. Hence the bag is conducting. I guess that means that it acts as a Faraday Cage https://en.wikipedia.org/wiki/Faraday_cage I tested the bag with an Ohmmeter expecting to get a low resistance but was off the scale, even on the kOhm settings, so perhaps I've misunderstood. A resistance like that is more like an insulator than a conductor.
