A multiple-ply anti-static paperboard having a layer of high-carbon content fiberboard sandwiched between two plies of anti-static material, the anti-static material being an anti-static plastic or low-carbon content paperboard. Dividers and pads made of such multiple-ply paperboard are used to form a plurality of walled cells within a container, each of the cells completely enclosing a packaged article susceptible to electrostatic discharge. The conductive layer forms a Faraday cage to electrostatically shield the packaged article, and the anti-static layer prevents conductive dust from contacting and adversely affecting the packaged article, as well as protecting the packaged article against the generation of static electricity internally of the container.

A container for use with an article which can be damaged by static electricity, comprising: a box having sidewalls and top and bottom walls; a plurality of relatively rigid dividers located in said box, each said divider comprising a layer of electrically conductive material sandwiched between and contacting two layers of an anti-static material, said electrically conductive material having a surface resistivity of less than 105 ohms per square inch and said two layers of anti-static material having a surface resistivity of between 109 and 1014 ohms per square inch; and wherein said dividers partially define a predetermined number of cells within said box, each said cell providing protection from both electrostatic discharge and conductive spall for a static electricity sensitive article to be packaged therein.
