    Abstract: The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.

  • Patent number: 7989054
    Abstract: The invention relates to a method for digitally printing a polymer-coated paper or board (1), to a paper or board suitable for the method and to the production of a product package equipped with digital prints. During digital printing, printing ink particles are applied in an electric field to the printing surface formed of a polymer coating at locations corresponding to the print, and the printing ink is adhered to the printing surface by fusion with the aid of infrared radiation. In accordance with the invention, the paper or board (2) to be printed is equipped with an inner coating layer (3) containing electrically chargeable ethene acrylate copolymer, such as ethene methyl acrylate copolymer (EMA), and with a polyolefin-based outer shield layer (4) on top of this, which contains e.g. low-density polyethene (LDPE) and provides mechanical strength, forming the printing surface receiving the printing ink.

  • Patent number: 7776435
    Abstract: The present invention is an electrophotographic transfer paper where at least one side of the base paper is given a coating layer with a pigment and an adhesive agent to form coated paper and where the aforementioned adhesive contains a branched poly(meth)acrylamide copolymer having a cationic groups and/or anionic groups and also has a weight average molecular weight of 50,000 to 1,000,000. The electrophotographic transfer paper in the present invention has superior high-speed throughput performance despite low basis weight and a low coating weight, therefore, good for high-speed copy machine and printer properties, especially, when it contained a printability improver in the coating layer, it has a good ink adhesion property and surface strength required in offset printing.

  • Patent number: 7682486
    Abstract: The invention provides a low density paperboard material and associated method for use in producing an insulated container, and is especially well-suited for making cups. The paperboard material comprises a paperboard web including wood fibers and expanded microspheres, and has a relatively low density ranging from about 6 to about 10 lb/3MSF/mil, a relatively high caliper ranging from about 24 to about 35 mil, and an internal bond strength of at least about 80×10?3 ft-lbf., preferably at least 100×10?3 lft-lbf. For applications such as cups the material is also coated on one or both sides with a barrier coating, preferably low density polyethylene, to limit liquid penetration into the web. The low density paperboard material of the invention is convertible for manufacture of containers, particularly cups, and exhibits insulative properties comparable to higher cost materials conventionally used to make cups.
