  • Publication number: 20200308768
    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.

  • Patent number: 10493700
    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.

  • Patent number: 10414105
    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.

  • Patent number: 10100259
    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.
