Abstract
A container for packaging electronic components which are susceptible to damage from electrostatic discharge or fields comprises a container made of paperboard or paper having an electrically conductive coating of electrostatic shielding material on the exterior surface thereof, and a coating of inorganic non-carbonaceous electrostatic dissipative material on the interior surface thereof. The electrically conductive coating preferably has an electrical surface resistivity of less than about 10.sup.5 ohms/square, and the inorganic, non-carbonaceous, electrostatic dissipative coating has an electrical surface resistivity of greater than about 10.sup.5 ohms/square. The electrostatic shielding material is preferably a carbonaceous material, and the non-carbonaceous, electrostatic dissipative material preferably comprises particles of amorphous silica or silica-containing material coated with antimony-doped tin oxide.
