ABSTRACT:
A method of manufacturing moisture-resistant corrugated paper board, particularly paper board intended for the manufacture of boxes, comprising an outer planar liner, an inner planar liner and a corrugated so-called floating disposed between the liners, wherein the liners and the floating consist of a paper which incorporates a rosin size. The invention is characterized in that the paper (5) on which the floating (7) is to be formed, is impregnated throughout its thickness with a first substance which includes a plastics suspension, preferably a styrene-butadiene suspension, and starch, and in that the paper (1, 3) for the liners, at least with respect to the surface (2, 4) of at least one of the liners (10) which is intended to face away from the floating (7) is coated with a second suspension which includes a plastics suspension preferably a styrene-butadiene suspension, and starch, and in that respective liners (10) are adhesively bonded to the floating (7).
