Reliability of anti-static packaging
I run a small webshop, so I ship a lot of chips in small quantities. The combination of styrofoam and a chip gives me the creepies. Styrofoam is excellent stuff to create static electrical charges (ever tried to clean a room from styrofoam bubbles?). So I think wrapping the chip in alu foil is in itself a good idea. But note: the alu foil I buy here has two sides, one is metallic, the other side is plasticised. If you do not pierce the foil, you must use it on the right side. But do not let styrofoam get near any chips.

My standard way of shipping small numbers of DIP chips (or non-smd MOSFETS) is to use the black plastic foam that is sold for this purpose. It is slightly conductive, enough to measure it with a multimeter: I get ~ 100k from two pins at 1 cm distance. For larger quantities I simply use the tubes in which the chips arrive. Small quantities of SMD chips I wrap in alu foil, or (preferrably) I buy them in cut tape.
