A method of manufacturing a decorative surface laminate incorporates a sheet of cellulose-based inclusion paper. The inclusion paper includes a print surface having a porosity greater than 1.25% and a decorative ink finish digitally printed directly onto the print surface of the inclusion paper. Multiple sheets of backing paper are stacked with the inclusion paper, such that the backing paper resides adjacent the inclusion paper on a side opposite the print surface. The inclusion paper and backing paper are impregnated with a thermosetting resin. Using heat and pressure, the impregnated sheets of inclusion paper and backing paper are combined to form a flexible high-density laminate panel.

The invention relates to a PVC composite flooring, comprising PVC base material and decorative board with alumina hot-pressed on the surface. The invention also relates to a process of preparation for the PVC composite flooring, comprising bonding the PVC base material and the decorative board with alumina hot-pressed on the surface using a hot-melt adhesive. The PVC composite flooring of the present invention is excellent in abrasion resistance, has remarkably improved resistance to indentation, is particularly excellent in compression stability.

Wood derived multilayer glued or laminated product having an integrated electric circuit, comprising a paper layer and conducting elements of conductive ink deposited on said paper layer, said elements being suitable for forming an electric circuit and said paper layer has a rugosity inferior to 60 m. The paper layer may be of kraft paper. The product may comprise one or more additional kraft paper layers, in particular having a hole for receiving electric components such that the top surface of product remains flat. The product may include a fibreboard substrate of MDF. The paper layer may be a decorative paper layer glued with the circuit facing the substrate. The manufacture process comprises depositing conductive ink elements on a paper layer having rugosity inferior to 60 m for forming an electric circuit; and incorporating, by gluing or laminating, said paper layer into the multilayer product.

The present invention is related, in one embodiment, to a paper packaging, totally free of plastic film, with water vapor barrier and tear resistance, whereby it may present perforations in specific regions. The packaging of the present invention further presents, in one embodiment, a sheet coated on the external face thereof with a water repellent agent. The packaging of the present invention presents the property of increasing the shelf life of the stored material.

A method and a process for the production of high pressure laminate is disclosed using conventional manufacturing equipment without the use of melamine-formaldehyde resin pre-impregnated decorative print, solid, or overlay papers or combinations thereof. The method and process of making the disclosed laminate product utilize the assembly of a plurality of pre-impregnated Kraft papers independently saturated with melamine-formaldehyde resin, phenol-formaldehyde resin, and/or a bilayer coated construction of Kraft paper simultaneously containing both resins on opposing surfaces. The resulting pre-impregnated Kraft based components are assembled into the core layer and combined with the desired decorative layer assembly composed of untreated decorative print, solid, and/or overlay papers, or combinations thereof, prior to consolidation into a finished laminate using standard heat and pressure commonly known to those skilled in the art.

A pipe insulation product including a core of insulating material and a laminate surrounding the core and bonded to the core. The core may include an outer surface; an inner surface; and a wall extending between the outer and inner surfaces. The laminate may include a foil or metallized polymeric film sheet, a scrim, a porous media sheet, and a polymeric film sheet bonded together via an adhesive. The laminate may include a closure flap that is configured to adhesively seal opposite ends of the laminate together to form a cylindrical tube with the core enclosed therein. The closure flap may be configured to include a curl that provides a greater closure flap adhesive seal.

Disclosed herein is an improved cover board product with a panel comprising a top surface layer comprised of paper or a fiberglass web; a bottom surface layer comprised of paper, a fiberglass web, nylon film, polyester film, polypropene film, or textiles; and a core layer comprised of paper and thermoplastic fragments connected by a thermoplastic bonding resin. The thermoplastic bonding resin is in a random pattern to less than 100% of the paper and thermoplastic fragment surface area.
