Description
Technical Field
[0001] The utility model relates to the technical field of packaging, in particular to a fine product box with a pulp molded outer box layer. Background Art
[0002] China Authorization Announcement No. CN 212767650 U, with an authorization announcement date of March 23, 2021, discloses a product packaging board and its packaging box, including a base panel, wherein the base panel includes a leather layer, satin cloth and paper, wherein the satin cloth and the paper are sequentially attached to the inner surface of the leather layer, and the outer surface of the leather layer is provided with an inlay area; a three-dimensional inlay, wherein the three-dimensional inlay is a three-dimensional pattern or text formed by composite stamping of a copper mold, and the three-dimensional inlay is transferred to the inlay area by a hot press or a high-frequency machine. The product packaging board of the utility model can be made of leather, satin cloth, paper, etc. as a base panel, and the three-dimensional inlay is fixed to the surface of the leather, satin cloth, and paper by high-frequency stamping. The three-dimensional inlay can be a decorative pattern or text, and the decorative effect is more beautiful.
