AI Technical Summary

Problems solved by technology

The technical defects of this technology are: ①One product can only use the same dot matrix number, and it is impossible to realize variable dot matrix numbers (that is, the dot matrix numbers assigned to all packaging bags of the same product are the same), ②Using The composite processing mode of the two base materials increases the production cost, ③ identifying the authenticity of the product through the password recognizer is not conducive to consumers' inquiry of the authenticity
The technical defect of this technology is: the anti-counterfeiting method is single and simple, and the laser holographic anti-counterfeiting film is compounded with the adhesive for anti-counterfeiting, but only the anti-counterfeiting material is used, which can hardly play the role of anti-counterfeiting
The main disadvantages of this technology: ①The method of two-layer film composite is used, which increases the finished product of the packaging bag;
The main disadvantages of this technology are 1. The two films are bonded together with the composite means, which increases the production cost of the packaging bag
②Single anti-counterfeiting means, only holographic anti-counterfeiting
[0007] Based on the above, it can be seen that the common defects in the current anti-counterfeiting packaging bags ① cannot achieve the integration of anti-counterfeiting packaging
② The number of anti-counterfeiting features is small, and the anti-counterfeiting level is low, so it is easy to be imitated by counterfeiters
③Compounding two layers of film by thermal compounding mode increases the production cost

Abstract

The invention belongs to the technical field of anti-counterfeiting materials and particularly relates to a digital holographic stamped anti-counterfeiting packing bag and a production method thereof. The digital holographic stamped anti-counterfeiting packing bag comprises a packing bag body and anodized aluminum; the anodized aluminum is composed of a base layer, a transfer layer and a gum layer; the transfer layer is composed of a release layer, an information layer and an aluminized layer. The anodized aluminum is printed on the packaging bag body by hot stamping. The production method includes selecting materials, designing, making a plate and die-pressing, aluminizing, printing and partially aluminizing, coating with a printed layer, tagging, applying gum, gilding, and cutting and hot-sealing. The digital holographic stamped anti-counterfeiting packing bag and the production method thereof have the advantages that holographic anti-counterfeiting packing, print anti-counterfeiting packing and digital anti-counterfeiting packaging are integrated by means of the bidirectional-positioning hot stamping technique, various anti-counterfeiting features are applied to the packing bag according to needs of customers and features of the packing bag, the single anti-counterfeiting means of the original packing bag is broken, unachievable untransferability of anti-counterfeiting labels is achieved, and secondary use of anti-counterfeiting contents is avoided.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting materials, and in particular relates to a digital holographic hot stamping anti-counterfeiting packaging bag and a preparation method thereof. Background technique [0002] As society's demand for flexible packaging increases year by year, flexible packaging is covering the market due to its inherent characteristics of bright colors, novel patterns, and ease of use. However, since most small and medium-sized packaging companies do not have the ability to produce anti-counterfeit products, the anti-counterfeiting technology of packaging bags is lacking, which makes it possible for counterfeiters to take advantage of it and fail to play the role of cracking down on counterfeiting and protecting quality. In order to achieve the purpose of anti-counterfeiting, anti-counterfeiting functions can only be given to packaging bags through other channels. The existing technologies include: [00...
