Composite panels and methods of preparation are described herein. In some embodiments, the composite panel can include a first fiber reinforcement, a polyurethane composite having a first surface and a second surface opposite the first surface, wherein the first surface is in contact with the first fiber reinforcement; and a cementitious material adjacent the first fiber reinforcement opposite the polyurethane composite. The polyurethane composite can be formed from (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (ii) one or more polyols, and (iii) a particulate filler. The fiber reinforcement can be formed from a woven or non-woven material, such as glass fibers. The composite panel can further include a material, such as a second fiber reinforcement and a cementitious layer, in contact with the second surface of the polyurethane composite. Articles comprising the composite panels are also disclosed.

A cleaning pad for electronic devices includes a first layer and a second layer. The first layer has a top surface and a bottom surface. The second layer has a top surface and a bottom surface removably attached to the top surface of the first layer. The bottom surface of the second layer includes an interior portion fabricated from a cleaning material for cleaning a display of an electronic device, and an exterior portion surrounding the interior portion and fabricated from an adhesive material. The interior portion of the bottom surface of the second layer is sealed between the exterior portion of the bottom surface of the second layer and the top surface of the first layer.

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 packaging structure and methods of manufacturing a packaging structure. The packaging structure, for example, an edge protector, a corner board, etc., may generally include a first ply having a first width, a second ply having a second width, and a third ply having a third width wider than the first width and the second width. The second ply may be wrapped around at least one end of the first ply, and the third ply may be wrapped around the first ply and the second ply. The third ply may overlap at a portion (e.g., an intermediate portion, an apex, etc.) of the packaging structure.

The invention discloses a high performance plastic magnetic material, comprising a low surface energy layer, a magnetic layer and a printable layer, wherein the magnetic layer and the printable layer are arranged successively on a first side of the low surface energy layer; the low surface energy layer is an organic silicon pressure sensitive adhesive layer. The invention further discloses a preparation method, comprising the following steps: pretreating a magnetic powder with a coupling agent; mixing the pretreated magnetic powder with matrix components and auxiliaries to gain a mixture; extrusion compositing the gained mixture with a printable layer to gain composite paper having the printable layer and a magnetic layer; and applying a low surface energy layer on a side of the magnetic layer, opposite the printable layer. As no UV layer and no adhesive residue, the material of the invention is environmentally friendly and highly reliable.

Provided are cementitious panel that include a swellable material within a core layer, a dense layer, and/or a sheet of facing material that make up a cementitious panel, as well as methods of manufacturing such cementitious panels that include a swellable material and methods of providing a moisture or water barrier in a cementitious panel.

Articles, for example multi-ply fibrous structure-containing articles such as multi-ply sanitary tissue products, containing two or more fibrous structure plies, and more particularly to multi-ply articles containing two or more fibrous structure plies having a plurality of fibrous elements wherein the articles exhibit improved bulk and absorbent properties compared to known articles and methods for making same, are provided.

A tamper evident label is provided. The tamper evident label broadly includes a base ply of pressure-sensitive material and a top ply of pressure-sensitive material. The base ply and the top ply are laminated together to form the tamper evident label The base ply includes a first portion and a second portion. The second portion of the base ply includes internal cuts and deadened adhesive. The top ply includes a tab portion defined by tab cuts. The tab portion of the top ply and the region between the internal cuts of the base ply are configured to be removed from the tamper evident label to create visual evidence of tampering. Further, a method of constructing a tamper evident label and a method of using a tamper evident label are provided.

The present invention is directed to an improved gypsum board, such as an improved sound damping gypsum board. The gypsum board comprises a gypsum core including gypsum and a sound damping polymer. The gypsum core includes a first gypsum layer surface and a second gypsum layer surface opposing the first gypsum layer surface. In addition, a first encasing layer is disposed on the first gypsum layer surface and a second encasing layer is disposed on the second gypsum layer surface.
