ABSTRACT:
Provided is an improved corrugated containerboard that includes a corrugated medium sandwiched between and secured to a top liner and a bottom liner. The corrugated medium, top liner, and bottom liner each include fibers that are oriented in a machine direction, and the corrugated medium defines a plurality of flutes that are oriented in the machine direction. The improved corrugated containerboard is constructed from conventional paperboard which is drawn through a corrugation system in the machine direction. A first piece of paperboard is drawn between a pair of dies to form the corrugated medium with flutes oriented in the machine direction. A second and third piece of paperboard are glued to either side of the corrugated medium to form the corrugated containerboard. Each die includes an engaging surface with ridges thereon, and the engaging surfaces are opposed and define a forming zone therebetween which the first piece of paperboard is drawn through. The first piece of paperboard is drawn into the forming zone at the front of the dies, and the front of the dies is tapered so that the formation of the flutes is staggered.
