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. Ken Javor Phone: (256) 650-5261 > From: Doug Smith <[email protected]> > Organization: D. C.
