You want something that's resistant to being pierced (or thicker than the length of the longest metal thing that sticks up from the circuit board), non-conductive, and is anti-static. Among commonly available materials, that leaves non-shiney cardboard (at least 2mm thick), wood, and PET plastic commonly used as the packing material for stuff that plugs into the motherboard, like memory modules and graphics cards (but a few such devices are packed in anti-static Mylar -- translucent white instead of transparent clear). Tough materials that aren't normally anti-static include ordinary PET (water and soda bottles, trays for microwavable dinners), Mylar (transparency sheets, but also sold as rolls of tape), kapton (dark brown transparent plastic used for insulating transistors from heatsinks, sold in sheets and in rolls of tape), and polycarbonate (Lexan). You can test for static by opening a faucet so it barely puts out a steady stream, then rub the material against a dry cloth and hold it near the stream to see how much it deflects the water. Pink bubble plastic caused less than 1cm of deflection, as did the rectangular black PET trays for microwavable Healthy Choice brand dinners by ConAgra. OTOH the round trays for Healthy Choice Steamers caused at least 2cm of deflection. Nestle's Lean Cuisine dinner trays were in between. Very scientific.
