Abstract: In the case of a method of producing a corrugated board for protecting electrostatically endangered articles 10 against electrostatic: discharges and electric fields, at least one corrugated layer 1 and at least one flat layer 2, 3 are glued together, a shield means 4, which contains carbon and/or graphite, being applied, prior to the glueing of said layers 2, 3, to the surface 40, 50, 60 of at least one layer which will be located in the interior of the corrugated board structure. This shield means 4 is applied as a layer, which comprises interconnected layer components 80 and intermediate interspaces 90 occupying a certain area, before the layers 1, 2, 3 are glued together in the area of said interspaces 90. The interspaces 90 are either completely free or covered by thinner layer components 90'occupying a certain area and constituting part of the shield means 4.

Abstract: In the case of a corrugated board W, which comprises at least one corrugated core layer 1 and at least one flat cover layer 2, 3, at least one electrostatically-shielding layer 4 is provided in the interior structure between the core layer 1 and said cover layer 2, whereas the outer side of the corrugated board W is provided with a conducting lacquer 5, 6 applied to the cover layer 2, 3. The conducting lacquer 5, 6 may be combined with a corrosion inhibitor 14. The shielding layer 4 is formed either continuously, or such that it comprises interconnected layer components 80 and intermediate, interruptions 90 occupying a certain area and interrupting the areas which are glued together, or such that it comprises highly compacted, interconnected layer components 12 and intermediate, less highly compacted layer components 13, or such that it comprises high, interconnected layer components 15 and intermediate lower layer components 16 which occupy a certain area.
