Abstract: A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.

Abstract: The invention concerns a heat-sealable biodegradable packaging material, which comprises a fibrous substrate (1) and one or more polymer coating layers (2) extruded onto said substrate. According to the invention the packaging material includes at least one polymer coating layer (2) containing at least 70 weight-% of polylactide (PLA) and at least 5 weight-% of polybutylene succinate (PBS) or its derivate blended therewith. Optionally an acryl copolymer such as ethylene butyl acrylate glycidyl methacrylate terpolymer (EBAGMA) may be included in the polymer blend. The invention further concerns a heat-sealed container, such as a disposable drinking cup, and a heat-sealed product package made from the packaging material, as well as uses of PBS or its derivates as blends with PLA in extrusion coating, for improving adhesivity of the coating to the fibrous substrate and reduced raw edge penetration to the packaging material, especially penetration of hot coffee held in the drinking cup.

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: 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.
