Anti Static Bag
He’s being disingenuous. You can zap the components by applying a charge from the outside of the bag. It takes a bigger charge through the metalized (static shielded) bag than the pink (static dissipative) bag. The purpose of the coating on the bag is not to shield against external high-voltage charges though. It is there to keep the bag itself from generating massive internal static charges and zapping the components during normal movement while the hardware ships.
I’ve moved a whole lot of gear wrapped in pink bubble wrap. Sometimes with an external shielded box, sometimes not, really depends on how much the gear is worth. But if you ever ship electronics wrapped in a couple of layers of normal bubble wrap, you are looking for trouble. Two layers of non-conductive plastic with an air gap rubbing together will build a charge.
