A method for forming a heat-reflective blank includes laminating at least one thermal film sheet at a predetermined position on a first linerboard sheet such that a laminated sheet is formed, and feeding the laminated sheet into a corrugating machine. The method further includes coupling the laminated sheet to a corrugated medium sheet and a second linerboard sheet such that a corrugated sheet is formed. The corrugated medium sheet is between the first linerboard sheet and the second linerboard sheet and the thermal film sheet is positioned on an outer surface of the corrugated sheet.

A waterproof corrugated paper includes at least one stone paper medium and at least one stone liner paper, wherein the at least one stone paper medium includes a first fluting surface. A stone glue is utilized to adhere the at least one stone liner paper and several wave crests of the first fluting surface. The stone glue includes a linear polyolefin plastic material and an inorganic material. The linear polyolefin plastic material is 30 wt %-70 wt % based on the stone glue, and the inorganic material is 30 wt %-70 wt % based on the stone glue. The waterproof corrugated paper provided by the present invention is waterproof and frost-resistant, which is adapted to package cooled or frozen food. A manufacturing method, a manufacturing apparatus, and a usage of the waterproof corrugated paper are also provided in the present invention.

A moisture resistant poultry box having a composite structure with a fluted paper medium, a top backing board assembly secured to one side of the fluted medium and a bottom backing board assembly secured to the other side of the fluted medium. The backing board assemblies and the fluted medium are impregnated with a hydrogenated triglyceride, and each backing board assembly has PET film glued thereto covering an outside surface to provide moisture resistant recyclable poultry box so that it has a Cobb value ranging between about 0 to about 1.

A corrugated cardboard production plant with double output side includes a corrugation unit, configured to form a composite cardboard sheet, the corrugation unit includes a corrugator and a plurality of continuous paper web storing units, and a first processing station arranged downstream of the corrugation unit along a first direction of movement of the composite cardboard. The plant also includes a second processing station arranged downstream of the corrugation unit in sequence along a second direction of movement of the composite cardboard different from the first direction of movement.

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.

A plant (10) for the production of corrugated cardboard comprising: a corrugating unit (36) adapted to produce containerboard, and a double baker (60) adapted to receive the containerboard. The corrugating unit (36) is positioned in proximity to an output end (66) of the double baker (60). The plant (10) further comprises a transfer unit (72) adapted to receive the containerboard and move it. The transfer unit (72) comprising: an input end (722) for the containerboard positioned in proximity to the corrugating unit (36), and an output end (724) for the containerboard positioned in proximity to an input end (64) of the double baker (60).

The invention relates to a method and an apparatus for the production of a corrugated cardboard product. The apparatus comprises a first one-sided machine and a second one-sided machine which are provided in each case with a press-down belt and with a first and a second grooving roller respectively. The first and the second grooving roller are designed for embossing a wave profile onto a first and a second paper web respectively. The press-down belts serve, together with the respective grooving rollers, for connecting the first and the second paper webs in each case to a non-corrugated web for the production of a first and a second single-flute corrugated cardboard web respectively. The first one-sided machine is equipped with a first oblique guide roller, the axis of rotation of which is inclined at a vertical inclination angle between side margins of the first paper web.

A corrugated cardboard plant, including at least one corrugated cardboard production device for producing at least one corrugated cardboard web laminated on one side, having a respective corrugated web and a cover web; a connection device, disposed downstream of the at least one corrugated cardboard production device, for connecting the at least one corrugated cardboard web laminated on one side and a lamination web to one another, while forming an at least three-ply corrugated cardboard web; at least one cutting device for generating corrugated cardboard sheets from the at least three-ply corrugated cardboard web; and at least one individual code reading device for reading corrugated cardboard sheet individual codes on at least one of the webs of the at least three-ply corrugated cardboard web and/or on at least one of the webs for forming the at least three-ply corrugated cardboard web and/or on the corrugated cardboard sheets.

A corrugated cardboard plant has a corrugated cardboard production assembly having at least one device for producing at least one corrugated cardboard web which is laminated on one side, and a connecting device for generating a corrugated cardboard web which his laminated on both sides and which comprises the at least one corrugated cardboard web which is laminated on one side. The corrugated cardboard plant furthermore has a printed web/lamination web production assembly which has a printing device for printing a printed web, a printed web storage device, and a lamination web unwinding device for unwinding a lamination web. The corrugated cardboard plant moreover has a coupling/uncoupling assembly having a coupling device for coupling the printing device to the corrugated cardboard production assembly while using the printed web as the lamination web in the corrugated cardboard production assembly, and/or an uncoupling device for uncoupling the printing device from the corrugated cardboard production assembly while using the lamination web in the corrugated cardboard production assembly.
