The point of the tinfoil (aluminum foil as some prefer to call it, as that is what it is really made out of) would be to dissipate the static electricity when you touch it, so that only a small shock gets through to the components. NEVER put your electronics in a plain plastic or ziplock bag. Have you ever seen how much static they build up? It's an almost sure-kill way of transporting electronics. The same thing will happen with styrofoam peanuts. However, wrapping it in foil and then putting it in a box with peanuts is the best way to transport, IMO. Either that or just a plain box with nothing in it. The VERY best way is to use real antistatic bags. Also, never put your stuff on the outside of antistatic bags, as the outside is plain plastic and will act the same as a ziploc bag.
