The board product may further include one or more facings that are adhesively coupled to either the corrugated medium, the embossed medium, or both. Generally speaking, a corrugated medium may be characterized as a paper product that exhibits flutes induced by a cross-corrugating process such that the induced flutes are perpendicular (or at least not congruent) with the machine direction of the paper product. An embossed medium may be characterized as a paper product that exhibits flutes induced by a linear-embossing process such that the induced flutes are aligned with the machine direction of the paper product. A resultant board product is stronger and more efficiently produced because of the linearly-embossed medium harnessing the natural strength of the paper in the machine direction. ## Claims ### Claim 1 A board product, comprising: a first medium formed from a first paper having a machine direction and cross direction, the first medium having one or more flutes aligned with the machine direction of the first paper; and a second medium formed from a second paper having a machine direction and a cross direction, the second medium affixed with respect to the first medium and having one or more flutes aligned with the cross direction of the second paper. ### Claim 2 (depends on 1) The board product of claim 1, further comprising a facing adhered to the first medium. ### Claim 3 (depends on 1) The board product of claim 1, further comprising a facing adhered to the second medium. ### Claim 4 (depends on 1) The board product of claim 1, wherein the first medium is adhered directly to the second medium. ### Claim 5 (depends on 1) The board product of claim 1, further comprising a facing adhered to the first medium and adhered to the second medium such that the facing is affixed between the first medium and the second medium. ### Claim 6 (depends on 1) The board product of claim 1, wherein the first medium further comprises flutes induced through embossing. ### Claim 7 (depends on 1) The board product of claim 1, wherein the first medium further comprises flutes induced through scoring. ### Claim 8 (depends on 1) The board product of claim 1, wherein the second medium further comprises flutes induced through corrugating. ### Claim 9 (depends on 1) The board product of claim 1, wherein the first medium further comprises flutes having a size corresponding to an E-flute profile. ### Claim 10 (depends on 1) The board product of claim 1, wherein the second medium further comprises flutes having a size corresponding to a C-flute profile. ### Claim 11 (depends on 1) The board product of claim 1, wherein the flutes in the first medium are not congruent with the flutes in the second medium. ### Claim 12 A method for making a board product with improved structure, the method comprising: embossing a first paper in a machine direction, the embossing resulting in an embossed medium having flutes induced in the machine direction; corrugating a second paper in a cross direction, the corrugating resulting in a corrugated medium having flutes induced in the cross direction; and affixing the embossed medium with respect to the corrugated medium. ### Claim 13 (depends on 12) The method of claim 12, further comprising adhering the embossed medium directly to the corrugated medium. ### Claim 14 (depends on 12) The method of claim 12, further comprising adhering the embossed medium to a first side of a facing and adhering the corrugated medium to a second side of a facing. ### Claim 15 (depends on 12) The method of claim 12, further comprising adhering a facing to the embossed medium such that the facing is disposed apart from the corrugated medium. ### Claim 16 (depends on 12) The method of claim 12, further comprising adhering a facing to the corrugated medium such that the facing is disposed apart from the embossed medium. ### Claim 17 (depends on 12) The method of claim 12, wherein the embossed medium comprises flutes having an E-flute profile and the corrugated medium comprises flutes having a C-flute profile. ### Claim 18 A machine, comprising: a first paper feed roll configured to feed paper to a corrugating stage; a second paper feed roll configured to feed paper to an embossing stage; at least one pair of corrugating rolls configured to cross corrugate the paper fed to the corrugating stage to produce a cross-corrugated medium; at least one pair of embossing rolls configured to linearly emboss the paper fed to the embossing stage to produce a linearly-embossed medium; a stage for combining the cross-corrugated medium with the linearly-embossed medium. ### Claim 19 (depends on 18) The machine of claim 18, further comprising: a third paper feed roll configured to feed a first facing to the stage for combining such that the first facing is adhered to one of the cross-corrugated medium and the linearly-embossed medium for combining a facing with the combination of the corrugated medium and the embossed medium; and a fourth paper feed roll configured to feed a second facing to the stage for combining such that the second facing is adhered to the other of the cross-corrugated medium and the linearly-embossed medium. ### Claim 20 (depends on 18) The machine of claim 18, further comprising a third paper feed roll configured to feed a facing to the stage for combining such that the facing is adhered to the cross-corrugated medium and adhered to the linearly-embossed medium.
