The invention contemplates flexible sheet material having static-dissipative properties and adaptable to wrapping or otherwise containing electronic components or the like which are to be protected against damaging exposure to an electrostatic charge. The sheet material is basically of relatively high surface resistance and is static-dissipative by reason of printed application of a matrix design, using electrically conductive ink, such that at least first and second intersecting sets of spaced plural conductive paths are established at the printed surface. The material is non-sparking by reason of the printed conductive ink being disposed between layers of relatively high surface resistance.

A static-dissipative electrostatically shielding container comprising an enclosure of size to fully contain an electronic circuit component or the like, said enclosure being fabricated from composite flexible sheet material, wherein the sheet material comprises inner and outer layers of transparent material characterized by relatively high resistivity, with an interposed printed open matrix of electrically conductive ink on at least one of the two confronting adjacent surfaces of said inner and outer layers, said matrix providing first and second intersecting sets of spaced plural conductive paths, whereby the inner layer provides anti-spark protection as between the conductive matrix and an enclosed circuit component, and the outer layer provides anti-spark protection as between the conductive matrix and a conductive source of voltage external to the container.
