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 compound, 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 a method and an apparatus for deep-drawing a tray (1) from fiber-based sheet material (2), such as polymer coated board. The apparatus comprises a female moulding tool (3), which comprises a cavity (7) for forming the tray bottom outwardly, a male moulding tool (4), which comprises a plunger plate (11) for forming the tray bottom inwardly, the plunger plate being movable with respect to the cavity for forming the tray, and clamps (6, 15) with an interface for holding the sheet material and forming a tray rim flange. According to the invention by laterally distancing at least one of the moulding tools (3, 4) from the sheet material leeway is provided for free forming of the tray side walls while wrinkling or tearing of the same is avoided. Spacer plates (13) may be positioned behind the plunger plate (11), to adjust its position in relation to the cavity (7) of the female moulding tool (3). The cavity may have a separate bottom plate (8) and spacer plates (9) there below, or screw means may be provided for adjusting the distance of the bottom of the cavity from the clamp interface and thereby varying the depth of the tray.

Abstract: The invention relates to use of polylactide (PLA) as an extruded polymer coating on paper or board intended for the production of containers and packages, which are heated in a stove or microwave oven. According to the invention a polyfunctional cross-linking agent, such as trialkyl isocyanurate (TAIC), is blended with PLA, and the extruded coating layer is subjected to cross-linking electron beam (EB) radiation. PLA may be used as such or blended with another biodegradable polyester such as polybutylene succinate (PBS). EB radiation has been found to improve adhesion of the coating to the paper or board substrate, heat-scalability of the coating, and heat-resistance of the finished containers and packages.

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 and an extruded polymer layer (2) containing a blend of (i) 0 to 25 wt-% of a branched low-density polyethylene (LDPE) with a lower melt viscosity and (ii) 75 to 90 wt-% of a linear low-density polyethylene (LLDPE) with a higher melt viscosity. The packaging material of the invention comprises multilayer coatings, e.g. an adhesive innermost and a heat-sealable outermost layer (2, 4) of said blend and a vapor barrier middle layer (3) of at most 90 wt-% of high density polyethylene (HDPE). The layers (2, 3, 4) are 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: The invention concerns a method of manufacturing paper or board, the paper or board obtained by the method, and a method of producing a tray from the board. In a fibrous stock for papermaking is incorporated an amount of polymer coated fibrous particles, which even have a foaming agent such as moisture contained therein. A web is formed from the fibrous stock on a forming fabric of a paper or board machine, followed by pressing and drying to a finished paper or board. As the paper or board is sufficiently heated the foaming agent within the particles evaporates, causing expansion and foaming of the polymer coating, which adds to malleability of the board as it is moulded into a shaped article such as a board tray. The invention even covers production of doubly coated fibrous particles for use in said methods, the inner coating layer being of a foamable polymer with a higher melt flow rate and the outer coating layer being of a non-foaming polymer of a lower melt flow rate.

Abstract: A method of deoxygenation of tall oil as well as methods for the production of aliphatic hydrocarbons and polymerizable monomers from tall oil. Sulphurous crude tall oil together with hydrogen gas is fed into a reactor comprising a catalyst bed. The oil is catalytically deoxygenated by hydrogen in the bed by use of a sulfided metal catalyst, e.g. a NiMoS catalyst. The flow exiting the reactor is cooled down and a hydrocarbon-bearing liquid phase is separated from a gas phase, followed by subjecting the liquid phase to distillation for removal of useless aromatic hydrocarbons and then to steam cracking to form a product containing olefins such as ethylene or propylene. By regulation of the deoxygenation temperature to be at least 270° C. but less than 360° C. the yield is rich in linear and cyclic aliphates that usefully turn to olefins in the steam cracking, while formation of napthalenes is reduced.
