  • Barrier paper and paper cup
    Patent number: 11136164
    Abstract: A barrier paper includes a paper base material and a barrier layer containing cellulose fibers formed on the paper base material, in which an integrated value from 10.0 ?m to 500.0 ?m, obtained from a volume-based particle size distribution diagram when a dispersion containing the cellulose fibers is measured by laser diffraction, is 30% or more.
    Type: Grant
    Filed: October 11, 2018
    Date of Patent: October 5, 2021
    Assignees: TOPPAN PRINTING CO., LTD., NIPPON PAPER INDUSTRIES CO., LTD.
    Inventors: Kosuke Shimizu, Akiko Saiki, Kaori Yamabe
  • Method for evaluating cellulose nanofiber dispersion, cellulose nanofiber aqueous dispersion, and cellulose nanofiber-containing food, cosmetic, and rubber composition
    Patent number: 11105789
    Abstract: Provided is method for evaluating a cellulose nanofiber (CNF) dispersion, the method including: (1) a step of preparing 1.0 mass % of a CNF aqueous dispersion; (2) a step of adding a coloring material into the CNF aqueous solution and stirring with a vortex mixer; (3) a step of sandwiching a film of the coloring material-containing CNF aqueous dispersion between two glass plates such that said film has a thickness of 0.15 mm; (4) a step of observing, with a microscope, the film of the coloring material-containing CNF aqueous dispersion sandwiched between the two glass plates; (5) a step of sorting observed aggregates by size (diameter along major axis) thereof; and (6) a step of calculating a CNF dispersion index from the number of sorted aggregates and evaluating the dispersibility of the CNF aqueous dispersion.
