Abstract: The invention provides a method of controlling retention on a forming fabric in a paper making process, an intermediate product for use in the method, as well as use of material for the intermediate product. For making the intermediate product at least one paper making chemical is added to a slurry of fine cellulose fibres such as micro fibrillated cellulose (MFC), the specific surface area of those fibres being larger than that of the fibres of the main fibrous suspension for paper making, causing the paper making chemical being adsorbed on the fine cellulose fibres. This intermediate product is then incorporated in the main fibrous suspension before the suspension is supplied from the paper machine head box to the forming fabric. Other paper making chemicals may be added to the fibrous suspension before or after addition of the intermediate product, so that interactions between different chemicals are prevented. The invention permits an increased retention in general as well as improved control of retention of paper making chemicals separately and/or in relation to each other.

Abstract: The invention relates to a packaging board comprising a fibrous base and one or more polymer coating layers on one or both sides of the fibrous base. According to the invention the fibrous base contains the combination of an alkyl ketene dimer size, stearic acid anhydride, a wet-strength size and an aluminium com- pound, which give the board resistance to aggressive liquids as well as thermal treatment, particularly an improved resistance to raw edge penetration in such circumstances. The invention further relates to containers and packages made of the board, for instance disposable drinking cups, dairy product cartons and auto- clave packages, as well as use of the board for such purposes.

Abstract: The invention relates to methods for lowering the melt viscosity and thereby improving heat-sealability of a polyester. The invention also relates to a method for manufacturing a heat-sealed container or package from fibrous- based, polyester-coated packaging material, and a method for heat-sealing polyester. The solution according to the invention is subjecting polyester to electron beam (EB) radiation. The lowered melt viscosity allows a lower heat- sealing temperature, and permits sealing of polyester to an uncoated fibrous surface. The preferred polyester for the invention is polylactide, as such or as blended with another polyester.

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, fibre-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 vapour 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 present invention relates to a method of manufacturing aromatic hydrocarbons, which are suitable for the production of terephthalic acid, from tall oil-based raw material. According to the invention, the raw material that contains tall oil or its fraction is catalytically deoxygenated with hydrogen, and one or more aromatic hydrocarbons (A) that can be converted into terephthalic acid are separated from the deoxygenated reaction yield (10). The deoxygenation catalyst is preferably a NiMo catalyst and, in addition, a cracking catalyst can be used, such as an acidic zeolite catalyst. The separated hydrocarbon is preferably p-xylene, o-xylene or p-cymene. According to the invention, these can be converted by oxidation and, when needed, by a re-arrangement reaction into terephthalic acid that is suitable for the source material of the manufacture of bio-based polyethylene terephthalate.

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.
