ABSTRACT:
A repulpable sheet of moisture resistant corrugated board (10) having inner and outer linerboard sheets (12, 14, respectively) with a convoluted or corrugated sheet of corrugating medium (16) therebetween, the flutes (16a) of the medium being joined to the linerboard sheets by an adhesive. The inner and outer linerboard sheets are coated before being joined to the medium with moisture resistant coatings (20, 22, respectively), which do not detract from the repulpability of the corrugated board, and the corrugating medium is coated with a moisture resistant coating, which does not detract from the repulpability of the corrugated board, before being joined to the inner and outer linerboard sheets. Because of the character of the coatings applied to the inner and outer linerboard sheets and to the corrugating medium, the adhesive used to join the corrugating medium to the inner and outer linerboard sheets is a cold set adhesive.
