Isn't the real purpose of these bags to avoid static buildup so as to
prevent an ESD event to the contents? Granted any bag conductivity
contributes to shielding effectiveness if the bag is so sealed as to provide
continuity across the open end, but at what sort of Ohms per square are we
looking here?
I haven't measured, but I'm wagging thousands, so not much SE to begin with.
