Description

Technical Field

[0001] The utility model relates to a composite membrane structure of an inflatable shoe box, belonging to the technical field of inflatable shoe boxes. Background Art

[0002] In order to achieve an aesthetically pleasing product packaging effect, the outer surface of the inflatable shoe box is generally printed with colored ink with a metallic luster, and the colored ink with a metallic luster is generally prepared by mixing metal powder with colored ink and then printed on the outer surface of the shoe box.

[0003] The prior art "Application No.: 2023203057928" discloses a flat-angle inflatable shoe box with a buckle-inserted lid, comprising a box body and a lid composed of several groups of air columns, wherein the lid is arranged at the open end of the box body; the lid comprises a sealing top portion and a buckle-inserted portion.

[0004] During use, it was found that the above-mentioned prior art has a problem that the adhesion of the colored ink on the surface of the shoe box is reduced after the metal powder is added, and the colored ink is easily discolored after contacting with the volatile chemicals remaining on the shoes. The buckle part of the box cover is inserted into the interior of the shoe box, so the colored ink of the buckle part is easily stained on the shoes after fading, causing the shoes to be scrapped or returned by customers, thereby causing huge economic losses.

[0005] Therefore, how to provide an inflatable shoe box composite membrane structure that is not easy to fade is the research purpose of the utility model. Utility Model Content

[0006] In view of the deficiencies of the above-mentioned technologies, the utility model provides a composite membrane structure of an inflatable shoe box, which adopts a structure of oil printing plus a metal electroplating layer, which can not only ensure the metallic gloss effect of the color ink, but also ensure the adhesion of the color ink, making it not easy to fade; and the outer sides of the color ink layer and the metal electroplating layer are covered with a transparent protective film to isolate the surface from the shoes, so that even if they fade, it will not affect the shoes.

[0007] In order to solve the existing technical problems, the technical solution adopted by the utility model is:

[0008] A composite membrane structure for an inflatable shoe box, characterized in that it comprises an inner layer of an air column and an outer layer of an air column, the inner layer of the air column being a thin film structure, the outer layer of the air column being a composite membrane structure, which comprises a first protective film, a base film and a second transparent protective film from the inside out, a metal electroplating layer being provided on one side of the base film close to the first protective film, and a color ink layer being printed on one side of the base film close to the second transparent protective film.

[0009] Furthermore, an inwardly retracted space is provided at one end of the color ink layer, and the sum of the lengths of the space and the color ink layer is equal to the length of the base film.

[0010] Furthermore, one end of the inner layer of the air column is longer than the outer layer of the air column, and the other end is flush with the outer layer of the air column.

[0011] Furthermore, the base film is configured as a degradable organic biofilm.

[0012] The beneficial effects of the utility model are: 1. The structure of oil printing plus metal electroplating layer can ensure the metallic gloss effect of the color ink and the adhesion of the color ink, making it not easy to fade; 2. The outer sides of the color ink layer and the metal electroplating layer are covered with a transparent protective film to isolate the surface from the shoes, and even if they fade, they will not affect the shoes; 3. The color ink layer adopts an inward-retracted structure to prevent the cut edges of the color ink layer from fading and getting on the shoes; 4. The inner layer of the air column is longer than the outer layer of the air column, which isolates the cut edges of the metal electroplating layer from contact with the shoes, and prevents the cut edges of the metal electroplating layer from fading and getting on the shoes.
