Abstract: The invention relates to a polymer-coated packaging material, a method of manufacturing the same, and products, such as a disposable drinking cup, made from the material. The packaging material comprises a fibrous base (1) of paper or board, an innermost polymer layer (2) containing a blend of (i) 10 to 25 wt-% of a low-density polyethylene (LDPE) and (ii) 75 to 90 wt-% of a second polyethylene with a higher melt viscosity, said second polyethylene being selected from linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE), and an outer layer (3) of more than 90 wt-% of HDPE. An outermost layer (4) of a polymer blend similar to that used for the innermost layer (2) may be provided for heat-sealing. The layers (2, 3 and 4) may be brought and adhered to the fibrous base (1) by coextrusion. To maximize renewability of the materials HDPE and LLDPE as used for the structure are of biologic origin.

Abstract: A method and an arrangement are disclosed for producing an electrically conductive pattern on a surface. Electrically conductive solid particles are transferred onto an area of predetermined form on a surface of a substrate. The electrically conductive solid particles are heated to a temperature that is higher than a characteristic melting point of the electrically conductive solid particles, thus creating a melt. The melt is pressed against the substrate in a nip, wherein a surface temperature of a portion of the nip that comes against the melt is lower than said characteristic melting point.

Abstract: The invention discloses a method of producing a filler composition to be used in paper or board production, said method comprising providing a suspension comprising calcium hydroxide and performing carbonation of the calcium hydroxide to form precipitated calcium carbonate (PCC). The invention is characterized in that starch and/or carboxy methyl cellulose (CMC) is added to the suspension during said carbonation of calcium hydroxide. The method of the invention enables an increased filler content in paper or paperboard without substantially increasing the dusting tendency or decreasing the strength of the paper or board.

Abstract: A hydrophobically sized fibrous web layer, preparation of a fibrous web or a fiber-based coating, a multilayer board product having at least a middle layer formed of said fibrous web, as well as use of a heat-sensitive surfactant for said methods and products, whereby microfibrillated cellulose (MFC) and hydrophobic size are brought to a foam with water and the heat-sensitive surfactant, the foam is supplied to a forming fabric of a paper or board machine, dewatered by suction of air through the forming fabric, and dried to a web product. Alternatively the foam may be supplied onto a premade fibrous web and dried to form a coating layer. The hydrophilic functionality of the surfactant contained in the web may be destroyed by heating. Pulp of a greater fiber length, such as CTMP, may be included, to provide improved wet and dry tensile strength for the paper and board products.
