A flexible packaging material including: a core portion having a geometrically patterned structure defining two spaced-apart substantially planar faces and providing air space therebetween, the core portion including cellulosic fiber-based walls having a core grammage; and at least one cellulosic fiber-based liner bonded to a respective one of the planar faces of the core portion and having a liner grammage lower than the core grammage, the material being flexible along a plane defined by the at least one liner.

Manufacturing decorative panels by using a web-fed inkjet printer. During the feeding of the to-be-printed substrate, the tension of the substrate is controlled by a dancer unit (720) which includes a dancer roll (200), having a connector (120) on both side ends of said roll, and wherein both connectors (120) are connected to a pair of parallel guiders (110) for floating said roll along a floating path (210); and wherein the step of controlling comprises the step of moving one guider (110) of said pair of guiders (110) parallel to said floating path (210) whereby the dancer roll (200) is tilted.

The invention relates to a method for producing a paper web which is suitable for and/or designed to form a layer, in particular the core layer of a laminated board, by impregnating the paper web with a resin and subsequently curing the resin, comprising:a first paper layer (1) made of a first material (3), anda second paper layer (2) which is connected to the first paper layer (1) over the surface thereof and which is made of a second material (4), whereinthe first material (3) of the first paper layer (1) has a higher degree of absorbency for the resin than the second material (4) of the second paper layer (2). The invention is characterized in thatthe second paper layer (2) is provided with an agent (5) for increasing the absorbency for the resin.

A laminate for application onto a support material having a resin-impregnated decorative layer and at least one resin-impregnated core layer. The decorative layer and the at least one core layer are adapted for being pressed together under high pressure and heat. A technical problem of improving a laminate for application onto the support material is solved in that the decorative layer and the at least one core layer can be compressed by a short-cycle press and have a width of more than 1800 mm. A method for producing the laminate is also provided.

A sheathing panel with an integrated weather-resistant membrane or layer, with a grid overlay. The grid is made of material able to maintain its structure and integrity while being subjected to the pressing process described herein. The grid may be integrated into the WRB membrane itself during the WRB membrane manufacturing process. In the alternative, the grid may separately added during the panel manufacturing process, with the grid being placed underneath or on top of the WRB membrane.

A method for manufacturing a laminate includes a carrier material and a cured thermosetting resin. The resin is cured using a catalyst showing one or a combination of two or more of the following properties: the catalyst has a pressure activatable catalyst; the catalyst has an encapsulated catalyst; the catalyst has an organic carboxylic acid. A method is provided for impregnating a paper layer, and an aminoplast resin catalyst is used in the method.

One aspect of the present specification provides an eco-friendly semi-noncombustible exterior material including: a core part (10) formed by impregnating a paper or fabric base with a triazole-modified phenolic resin; an outer skin (20) formed by impregnating a paper substrate with a melamine resin and joined to at least one surface of the core part; and a UV film (30) formed on at least one surface of the outer skin, and containing a polymethyl methacrylate resin.

The present disclosure describes laminate products capable of retaining a wood stain or colorant. The unique resin binder formulations, preferably a melamine formulation, and products include porosity-promoting agents that result in the resin binder layer having a porous surface capable of being stained with a wood stain or other colorant, while still having the favorable properties of traditional laminate products. The methods of the invention produce a laminate product that can be stained with a variety of stains and colorants after manufacturing to suit the individual builder's or homeowner's preference. The stainable laminate products may include a decorative paper layer sandwiched between a backing layer and a resin binder layer embedded with a porosity agent, such as, silica, wax, mica, calcium carbonate, silane, kaolin clay, crystalline silica, corn starch, feldspar, talc, or combinations thereof. The stainable resin binder layer optionally has a textured top surface.

The present invention relates to a method for producing an interim sheet, the method comprising the steps of: k) providing at least a first sheet material impregnated with a first thermosetting resin, and a second sheet material impregnated with a second thermosetting resin; and, l) pressing the first and second sheet materials together, at a temperature of between 60 C. and 115 C., for between 40 and 130 minutes, such that the first and second thermosetting resins become liquid, and pressing with a first sufficient pressure such that the first and second sheet materials fuse to form an interim sheet without fully curing the first and second thermosetting resins such that the first and second thermosetting resins can flow again when heated.
