    摘要: 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.

    摘要: The invention relates to a method of manufacturing a shaped tray or plate of fibrous material. The method comprises the steps of (i) providing a fibrous pulp, in which the fibres substantially consist of at least 85 wt-% of softwood fibres having an average fibre length of at least 2.0 mm and at most 15 wt-% of broke having a fibre length of about 0.05 mm to 1.0 mm, (ii) turning the pulp into a foamed suspension, (iii) supplying the foamed suspension from a headbox to a forming fabric of a board machine to form a fibrous web, (iv) drying the web to obtain a dried web having a compressibility in the thickness direction of at least 20%, and (v) including the web as a layer in a board, which is turned to said tray or plate by thermopressing or deep-drawing. The invention even covers shaped trays and plates produced by use of the method.

    摘要: 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.
