A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are impressed (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are impressed will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and folded. A lack of precision in folding a board product leads to gap variation and fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when folded.

A corrugated sheet metal wall sheathing for resisting external excitations such as wind or earthquake of light-framed wall structures. The sheathing has sheet profile proportioned to insure the top flutes deform laterally and yield at the end of the flute before the onset of any failure mode. A transverse slot in included in each top flute and adjacent web of the sheathing and spaced at intervals along the length of the sheathing.

Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are imprinted (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are imprinted will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and bent. A lack of precision in folding a board product is known as fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when bent. Hence, the articulated portion “fishtails” out of alignment. Having precisely located impression lines in register to underlying flutes of a medium ensures correct and precise articulation.

A system and method for producing a board product made from paper products that have embossed medium that features an improved structural profile. The improved structural profile may include a triangular flute pattern wherein each flute may exhibit a first linear leg support and a second linear leg support that each support a center apex structure. The apex may have a substantially flat portion that is configured to engage a facing. As such, the board product may further include one or more facings that are adhesively coupled to the embossed medium. Further, the apex of each “triangle” may also have a groove or channel for receiving an adhesive in a continuous and uniform manner.

A system and method for producing a board product characterized by having two corrugated mediums and at least one embossed medium in the board product. 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.

Flame-resistant paper for radio wave absorber members includes 40 to 70% by mass of pulp; 5 to 50% by mass of aluminum hydroxide powder; and 3 to 15% by mass of a flame retardant consisting of a polyborate, wherein the flame retardant consisting of a polyborate is contained in an amount of 7 to 25% by mass relative to the amount of the pulp.

A smoothly bendable board including a middle layer, a first outer layer attached to the middle layer and a second outer layer attached to the middle layer is disclosed. The second outer layer has a lower bending stiffness according to ISO 5628 than the first outer layer such that the smoothly bendable board is outwardly bendable only in a direction towards which the second layer faces. A method for producing a smoothly bendable board is also disclosed.
