Answer to: Substitute for an anti-static bag?Foil was used back before there was such a thing as astatic bags. I had CMOS chips stored for decades on my truck that only had foil around them. Later you got foil around the chip seated in conductive foam. Plastic tubes for chips came later. I'd wrap in foil, then paper to protect the foil. Certainly better then how I've gotten PC boards off eBay just dropped in a box with packing peanuts. Note my experiences related above come from semiconductors and PC boards from the late 60s and 70s. By the 80s we were getting bags and foil was abandoned. If I had all the options before me, I'd go with the bag too.
