A bag for holding and protecting articles sensitive to mechanical damage as well as to electric fields, the walls of the bag being essentially a layer of cushiony microfoam about 1 to about 4 millimeters thick, an essentially unfoamed polyethylene coating about 25 to about 100 microns thick on the inside surface of the microfoam, an essentially unfoamed support layer on the opposite surface of the microfoam, at least one face of the support layer being treated to protect the bag contents against external electric fields, and the polyethylene coating carrying sufficient antistat to protect the bag contents against the build-up of static electricity to the intensity that damages those contents when they are slid into the bag.
