Problems solved by technology

[0008] The traditional anodized aluminum hot stamping foil production process has the following disadvantages: when the traditional anodized aluminum hot stamping foil is hot stamped on a transparent material (such as a plastic film), only the front side of the anodized aluminum hot stamping foil can show the various colors of the front side, and only the reverse side of the transparent material can be displayed. You can see the off-white color on the reverse side of the anodized aluminum hot stamping foil; while the graphic printing of the plastic flexible packaging composite film is printed on the reverse side of the film, and then the printed ink surface is dry compounded with the heat-sealing layer, which requires the use of an anodized aluminum hot stamping foil The hot stamping pattern can only be hot stamped on the surface of the composite film after dry lamination, so that it cannot be aligned with the printed pattern on the back of the film.

Abstract

The present invention provides a double-sided color electric aluminum hot stamping foil and a production method thereof. According to the present invention, after the double-sided color electric aluminum hot stamping foil is subjected to hot stamping on a transparent material, the front surface and the back surface of the stamped material can display the same or different colors; after the double-sided color electric aluminum hot stamping foil is used for plastic composite film printing, the hot stamping picture-text can be lined while the printing on the back surface, and the precise chromatograph edition of the hot stamping pattern and the ink printing picture-text can be achieved; and after the product is compounded, the printing layer and the hot stamping layer are positioned on the inner surface of the printed film, the gloss is strong, and the scratch caused by external force cannot be generated.

Description

technical field [0001] The invention relates to a double-sided color anodized aluminum hot stamping foil and a production method thereof. Background technique [0002] Anodized aluminum hot stamping foil is a film-like material for thermal transfer made by coating several layers of coatings with different functions on the surface of plastic films and vacuum-evaporating an aluminum layer. It is widely used in paper, plastics, etc. After printing, it is processed to obtain text patterns or color blocks with metallic luster. [0003] The traditional process of making anodized aluminum hot stamping foil is: [0004] 1. Release layer: Use biaxially oriented polyester film (BOPET) to coat the release layer on the surface. [0005] 2. Color layer: apply color layer paint on the surface of the release layer, and add 0%~10% color material to the color layer paint to meet the customer's personalized color requirements. [0006] 3. Aluminum layer: The aluminum layer with a thickness...
