Embodiment Construction

[0025] The present invention is a cigarette label production process that replaces large-area bronzing with partial aluminum washing and transfer, and the steps are as follows:

[0026] 1. Base film coating: use 23μ thick PET base film as the substrate, use laser transfer coating to evenly coat the surface of the base film in the form of gravure printing, and dry it with infrared hot air to form a laser molded base layer for later use;

[0027] 2. Laser molding: Based on the coated PET base film, a molding working plate is installed on the molding machine, and the laser pattern on the molding working plate is transferred to the surface of the laser coating by hot molding, so that the surface of the base film is formed. Regular grooves required for laser effects, forming the base shape for directional reflections.

[0028] 3. Aluminum plating: aluminum plating by vacuum aluminum plating: in the aluminum plating machine, the coating of the base film forms an electrode, so that t...

Abstract

The invention discloses a process for producing a cigarette label by replacing large-area hot stamping with local dealuminization transfer. Currently, the large-area hot stamping cigarette label producing process has the problems of large equipment investment, high requirement on elasticity of a hot stamping film adhesive layer, difficulty in realization and the like. The invention adopts the technical scheme that the process for producing the cigarette label by replacing large-area hot stamping with local dealuminization transfer comprises procedures of coating a base film, carrying out laser die pressing, aluminizing, neatening the base film, printing a protection coating, dealuminizing and drying, carrying out fixed-length compound, carrying out transfer stripping, carrying out position slitting and carrying out printing application processing sequentially. The process is used for replacing a large-area hot stamping process, so that the realization difficulty of a large-area bottom hot stamping printing product is avoided. The process has high quality. Even a dot laser pattern can be realized. Meanwhile, the combination firmness of the pattern on paper is improved and the grade of the product is promoted. The investment level of equipment is reduced. The production cost is greatly reduced.

Description

technical field [0001] The invention relates to a manufacturing process of a surface pattern of a packaged product, in particular to a manufacturing process of a cigarette label in which partial aluminum washing is transferred instead of large-area bronzing. Background technique [0002] At present, the manufacturing processes realized by local large-area laser on cigarette labels mainly include large-area bronzing process and cold transfer (also called cold stamping technology) process. [0003] 1. Large-area bronzing process: a technology that uses high temperature + pressure to transfer the bronzing film to the surface of the printing material according to the required pattern. This process has the following problems: [0004] a. Large investment in equipment (large-area bronzing requires round stamping equipment, which needs to be imported). If the hot stamping pressure is unstable, it will lead to rough stamping surface effects, uneven surfaces, and many edge burrs, whi...
