Zusammenfassung: | The invention discloses a degradable paper cup formula and a preparation method thereof, and belongs to the technical field of edible containers. The formula comprises 40-70 parts of polylactic acid, 10-25 parts of PBAT, 15-30 parts of a paper pulp board, 1-10 parts of porous filler powder, 0.1-1 part of a waterproof agent, 0.2-1 part of a chain extender and 0.2-0.9 part of a dispersant. According to the preparation method disclosed by the invention, the production process of the paper-plastic cup is realized by adopting the processes of fiber treatment, material mixing, sheet extrusion, surface printing, die cutting, paper cup forming and the like; wherein the polylactic acid and paper fibers are mixed to directly extrude the paper-plastic sheet, so that the production process is simplified compared with the original film-coated paper, and meanwhile, the paper-plastic sheet is relatively good in forming performance and waterproof performance; in addition, due to combination of the paper fibers and the porous |
