  • Patent number: 12152115
    Abstract: A textured film is provided which comprises nanocellulose. At least a first surface of the film comprises a patterned, textured surface formed by repeating protruding regions and at least one non-protruding region arranged between said protruding regions. A particular height difference between the protruding and non-protruding regions can give liquid repellent properties. Methods for making the textured film are also provided.

  • Publication number: 20230339646
    Abstract: The present invention relates to a container for liquid containing food products, manufactured by press forming of a polymer coated fiber based substrate, said container comprising a bottom portion, a sidewall portion and a top flange portion, wherein said press forming has resulted in the formation a plurality of creases extending in a direction from the bottom portion to the top flange portion and further across the top flange portion. The container comprises an indentation pattern (130, 140, 150, 160, 170, 180, 190a, 190b, 200) formed at a creased inner surface of said sidewall portion and/or at a creased top surface of said top flange portion, said indentation pattern preventing migration of liquid from a liquid containing food product in the container along said creases. The invention relates also to a method for manufacturing such container.

  • Patent number: 11346052
    Abstract: A surface treatment composition for paper, board or other fibrous webs. The composition of the invention comprises particles which comprise an active material and a supporting material. The active material comprises a salt of a multivalent metal, such as a divalent or trivalent metal. In accordance with the invention, the supporting material is adapted to release the active material from the particles when subjected to heat and/or pressure and/or a change in pH. Consequently, the active material's adverse effects on the rheology of the composition are avoided while its desired effects on the surface characteristics are retained or enhanced.

  • Publication number: 20080295984
    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 could take place, for example, by burning the surface of the fiber layer (1) or by engraving it. 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.
