A method of producing a printed product, wherein a formulation for production of a first layer as sealing layer is applied to the substrate and the formulation has at least one monomer, oligomer or prepolymer having at least one crosslinkable functional group. Subsequently, the first layer is cured and a second layer is applied at least to regions of the first layer, wherein the second layer has a coherent surface in the printed regions. Further, a printed product having a substrate, a first layer and a second layer, wherein the first layer and the second layer comprise an organic crosslinked lacquer and have a coherent surface, and wherein the first layer is transparent and has a layer thickness in the range from 1 to 10 μm. The second layer has been applied at least to regions of the first layer, such that the first layer is disposed between the substrate and the second layer.

The present disclosure describes a method to modify dried polymer films using printed crosslinking agents, including that the crosslinked polymer resulting from the method exhibits greater insolubility compared to crosslinked polymers made where the crosslinking agent and the polymer are combined and applied as a homogenous solution. Articles of manufacture generated by such a method are also disclosed.

A heat-sealable barrier paper having a) a carrier substrate having a front side and a back side opposite the front side, b) optionally an interlayer comprising a binder and disposed on the front side of the carrier substrate, c) a first barrier layer comprising a crosslinked polysaccharide and disposed on the front side of the carrier substrate or, if there is an interlayer, on the interlayer, d) a second barrier layer, disposed on the first barrier layer and consisting of or comprising i) an acrylate copolymer and/or ii) a wax based on a vegetable oil, the use of a barrier paper for packaging products, a method for heat-sealing a barrier paper, and to a method for producing a barrier paper.

Release paper base paper, includes: a substrate; and a coating agent containing a polyvinyl alcohol (A) and a compound (B), the substrate coated with the coating agent, wherein the compound (B) is unsaturated carboxylic acid or a derivative thereof having a pKa of less than 4.00, and 0.1 part by mass or more and 20 parts by mass or less of the compound (B) is contained based on 100 parts by mass of the polyvinyl alcohol (A). The release paper base paper of the present invention is excellent in sealing properties for silicone and waterproofness. The release paper base paper of the present invention is also capable of accelerating curing of silicone in a release layer.

A repulpable paper strap includes a plurality of paper strings, and a binder that binds the paper strings together, the binder including a partially hydrolyzed polyvinyl alcohol and a fully hydrolyzed polyvinyl alcohol. Related methods of forming the repulpable paper strap is also provided.

The invention relates to a method for manufacturing thermoplastic poly(vinyl alcohol) derivative in a melt state reaction and a product thereof, wherein the method thermoplastic poly(vinyl alcohol) that has been dried is heated and admixed with an organic acid anhydride that has a catenated carbon structure which ends into a vinyl group, such that a mixture is obtained which is above the melting point of the mixture, thereby causing an ester bond forming condensation reaction in a melt state, wherein at least some of the organic acid anhydride reacts with hydroxyl groups of the thermoplastic poly(vinyl alcohol), such that reaction product is formed which contains carboxylic acid residue and thermoplastic poly(vinyl alcohol) derivative which contains ester bonded pendant chains of which at least some end into vinyl groups. The invention further relates to a method for manufacturing a paper substrate and a product thereof, which contains a primer layer that contains the reaction product.

This invention refers to a manufacturing process for a high-performance resin-saturated decorative foil, designed for surface lining, both outdoors and indoors. The decorative foil can be used as a decorative lining for HPL-High-Pressure Laminate-panels and CPL-Continuous-Pressure Laminate-panels, as well as to be adhered to any flat or curved 2D surface.

Packaging material formed from a substrate and three coating layers or in some instances at least three coating layers, each coating including an aqueous polymeric solution or dispersion dried to form a continuous film such that the packaging material is provided with tailored performance attributes including desired moisture vapor transmission rates, oxygen permeation rates, oil and grease resistance peel strength. The materials forming the packaging material may be compostable or biodegradable.

A laminate includes a paper substrate, an anchor coat layer disposed at a one-surface side of the paper substrate, and a barrier coat layer disposed at a one-surface side of the anchor coat layer. The paper substrate has a density of 0.72 g/cm.sup.3 or more. The barrier coat layer contains a gas barrier polyurethane resin.

The present invention provides a method for manufacturing a barrier laminate in which barrier materials is directly coated on a paper substrate, by suppressing penetration of barrier materials into paper through the paper surface sizing or coating process and increasing density and smoothness of the paper through the calendering process.
