A transparent box for protecting against damage from electrostatic discharge and sheet material to be cut into a box blank for forming the same. The box blank has an electrically insulating, transparent, polymeric sheet and a continuous, transparent, electrically conductive layer disposed on at least one surface of the polymeric sheet. The polymeric sheet has grooves on at least one surface forming fold lines and the sheet material has sufficient stiffness to enable the sheet material when cut into a box blank and folded into a box to hold its shape. Grooves formed into the surface of polymeric sheet 14 and the subsequent folding do not disturb the continuous electrically conductive layer enabling the completed box to have complete electrostatic shielding from all directions.
