摘要： A method for manufacturing a paperboard structure includes passing a paperboard substrate through a hot-hard calender to yield a calendered paperboard substrate, the hot-hard calender including a nip defined by a thermo-roller and a counter roller, wherein a contact surface of the thermo-roller is heated to an elevated temperature. The method then includes applying a basecoat to the calendered paperboard substrate to yield a basecoated paperboard substrate, the basecoat includes a basecoat binder and a basecoat pigment blend. The method further includes applying a topcoat to the basecoated paperboard substrate.

摘要： A system and method are provided for controlling archival sheet curl formation in image receiving media substrates on which images are formed using aqueous inks as the marking material. Archival curl occurs over time and is based on a partial coverage of the image receiving media substrates by the deposited water-based marking materials. A unique post-processing scheme applies selective aqueous clear fluid onto imaged substrates (cut sheets) to substantially counteract long-term archival curl formation in the individual image receiving media substrates. Both opposing sides of the cut sheet are processed in a manner that causes them to substantially equally undergo the generally irreversible shrinkage phenomenon that leads to archival curl, thus substantially canceling out the archival curl formation mechanism. A clear fluid is applied image-wise to portions of one or both sides of the image receiving media substrates to counterbalance the formed aqueous ink image.

摘要： A method of forming a coated boxboard product is provided. A boxboard product is formed without being processed by a Yankee dryer, and further comprises a plurality of fiber plies, including outermost plies forming the top and back sides and comprised of bleached chemical pulp, and medial plies disposed between the outermost plies and comprised of at least one of groundwood, pressure groundwood, chemithermo-mechanical pulp, recycled pulp, and broke. The boxboard product is precalendered with a surface conditioning device and then coated such that the coated boxboard product has a density of between about 500 kg/m3 and about 1000 kg/m3, and a basis weight of between about 150 g/m2 and about 500 g/m2, and the top side of the coated boxboard product has a PPS-s10 roughness of between about 0.8 μm and about 3.0 μm and a Hunter gloss of between about 30% and about 80%.

摘要： In the method, a release layer is formed on base paper to manufacture release paper. The base paper is calendered before forming the release layer in-line on the same production line. A further object of the invention is equipment for manufacturing release paper, which equipment can be used to form a release layer on top of a base paper. The equipment comprises a calender (4) located before the release layer forming unit (5) in-line on the same production line.

摘要： Polyethylene applied to high-density paper where the surface of the paper is modified in order to have a surface energy as close as possible to polyethylene and thereby achieve properties as barrier material for packaging of food. The good barrier property is a result of crystallisation of polyethylene on the paper's surface.

摘要： In the method for treating the surface of the web, liquid is added on the surface of a paper or paperboard web (W), possibly with other constituents. The absorbency of the surface of the paper or paperboard web is increased before liquid is brought on the surface of the web or simultaneously with bringing the liquid on the surface of the web. The method is used for wetting the surface of the web before calendering, or for coating the web in surface sizing or pigmenting. The absorbency of the surface is increased before bringing the liquid for example by means of a corona treatment, a flame treatment, an ozonization or by adding steam.
