    Abstract: The invention comprises a method for producing identification marks (5) on layer-structured paper or board (7) to be manufactured in a continuous web and the marked papers and boards obtained with this method. With this method, the marks (5) are made with a laser beam on a moving web form fiber layer (1), on which a second layer of material (6) is subsequently overlaid in such a way that the marks remain inside the layer-structure of the moving web. The second material layer (6) may comprise a second fiber layer or, for example, a polymer coating. The laser marking takes place by engraving the surface of the fiber layer (1). Inside the layer structure, the marks (5) are protected, but detectable with a detector to ensure the authenticity of the material. The marked paper or board is suitable for product packages to be protected against product forgeries.

    Abstract: The invention relates to a digital printing method and a paper or board applicable thereto. In digital printing, the surface of a paper or board is charged electrically, toner particles are brought to the surface in an electric field in accordance with the printing, and the particles are melted fast to the surface with the help of heat for forming the printing. According to the invention, the paper or board (2) is provided with a coating layer (3) containing an electrically chargeable acrylate copolymer of ethylene, which receives the toner that is fused to the coating with the help of infrared radiation. Suitable coating polymers are especially methyl, ethyl and butyl acrylate copolymers of ethylene (EMA, EEA and EBA). Especially in packaging boards, besides the digitally printable layer, the polymer coatings can comprise a water vapor or oxygen barrier layer for protecting the packed product, and a heat-sealable layer on the opposite side of the board for sealing the package.

    Abstract: The invention relates to a method of manufacturing board (2), a board provided by the method, and a container formed from the same, such as a disposable drinking cup. According to the invention, fiber-based stock is doped with a polymer (6), ending in a pulp web that is formed of this pulp on a board machine wire, and in a board layer (3) that is obtained from the same by pressing and drying. When the board layer is heated, the polymer melts and water vapor bubbles penetrate it, rendering the layer porous. The polymer used for the doping can comprise, for example, a low density polyethylene (LDPE) that has a melt viscosity of about 15. Pore-generating heating can be carried out for the board or only for the container manufactured from it. The porous layer prevents the hot drink enjoyed from the cup from burning the fingers of the user.

    Abstract: The invention relates to a method for manufacturing a disposable board drinking cup ( 10 ) and to the cup produced by the method. The cup is manufactured by folding a board blank between the cup mantle ( 5 ) and the collar ( 6 ), by bending and seaming the folded blank into a cone, the folding point forming the cup mouth ( 8 ), and by providing the thus seamed blank with a bottom. The cup thus formed comprises both a mantle ( 5 ) and a collar ( 6 ) bent downwardly from the cup mouth ( 8 ) and acting as a grip surface, making it easier to enjoy especially a hot drink from the cup. The shape of the cup mantle ( 5 ) and the collar ( 6 ) may be conically expanding, allowing the cups to be nested. The lower edge of the collar ( 6 ) can be equipped with a projection ( 12 ) for maintaining an air slot between the collar and the cup mantle.

    Abstract: The invention relates to an encapsulated blister package, which is especially a medicine package containing tablets ( 8 ) or pills. The package has the flat outer casing ( 1 ), most preferably made of cardboard, and the inner part ( 2 ) partly extractable from it, the inner part comprising the disc ( 7 ) formed as a blister package moutned rotatably onto the base ( 5 ). The base has an outlet opening or similar so that the tablet that has been brought to the opening by rotating the disc, can be pressed out of the disc and removed from the package through the opening.

    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.
