Uhhh... antistatic bags are antistatic because they are electrically conductive. That's how you fundamentally get rid of static charge; by conducting it somewhere else, making it non-static, and distributing the charge. Static destroys things because there's an off chance that enough static electricity will be built up at a point source to fry a component on contact. With antistatic bags, since the charge is dissipated, charge will never build up to damaging levels. Antistatic bags are either lined with a conductive layer or have a grid of conductive lines.
Things will only start to go haywire if you plug in or turn on the electrical component while it's wrapped in an antistatic conductive bag.
