Digital holographic anti-counterfeiting bottle cap and preparation method thereof

Abstract

The invention belongs to the field of anti-counterfeiting techniques of materials, in particular to a digital holographic anti-counterfeiting bottle cap and a production method thereof. The digital holographic anti-counterfeiting bottle cap comprises a cap 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 side or top of the cap 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, and performing hot stamping. According to the production method, the holographic printed digital anti-counterfeiting stamping foil is printed to the top and side of the cap body by hot stamping, and holographic printing and digital anti-counterfeiting are integrated. Anti-counterfeiting features are many, so that anti-counterfeiting performance is improved; meanwhile, untransferability, which cannot be realized, of anti-counterfeiting labels is achieved, and an environmental protection function is improved.

Description

technical field [0001] The invention belongs to the technical field of material anti-counterfeiting, and in particular relates to a digital holographic anti-counterfeiting bottle cap and a preparation method thereof. Background technique [0002] Due to fierce competition in the domestic beverage industry, wine industry, pharmaceutical industry, and cosmetics industry, many well-known companies have adopted the latest production technology and equipment, making them approach international advanced water products in all aspects. Among them, bottle caps are becoming more and more important. Whether in beverages, alcohol, daily chemicals, medicine, or other industries, anti-counterfeiting of bottle caps has become a crucial means of protection. The existing technologies include: [0003] 1. Anti-counterfeiting bottle cap with laser holographic pattern: it is composed of outer temperature-resistant shaping layer, transparent layer, decorative layer with laser holographic pattern...

AI Technical Summary

Problems solved by technology

The main disadvantages of this technology ① The number of anti-counterfeiting features is small (only holographic anti-counterfeiting is required), and the anti-counterfeiting strength is low

②Because the laser pattern is observed through the transparent layer, because the transparent layer is mostly transparent plastic and glass, it is easy to scratch and pollute, resulting in reduced transparency, so that consumers are not suitable to see the laser information on the decorative layer

③Through the refraction of light through the transparent layer, it is impossible to detect the second-line and third-line anti-counterfeiting means in the laser pattern, which is easy to play the role of misleading, so that counterfeiters can take advantage

The main disadvantages of this technology ①The password rules are simple and have been cracked (for example, the data covered by the two-dimensional code is 20100823901, 20100823902, 20100823903, ..., among them, the first eight digits are the production date of the bottle cap, and the last three digits are the bottle cap serial number), as long as the counterfeiter gets a few bottle caps, he can copy the data between any two bottle caps, so that many products will be faked as genuine, and the authenticity cannot be distinguished through its query module

loss of interests to consumers

② Due to the simple password rules, the logistics management function cannot be realized

③ Use the inkjet printer to print the digital on the bottle cap, the production process is simple, and because the inkjet ink is solvent in nature, it is not conducive to environmental protection

The main defects of this technology are: ① "When consumers consume this product, they must uncover the bottle cap pad and find the two-dimensional code anti-counterfeiting label, and then scan the two-dimensional code anti-counterfeiting label through terminal devices such as smartphones. This product is anti-counterfeiting and traceable, which means that consumers can only identify the authenticity after destroying or using the purchased product, which will cause some unnecessary disputes

Not conducive to protecting the rights and interests of consumers

②Since the two-dimensional code is set inside and is only isolated by a layer of gasket, the liquid in the bottle can easily soak the two-dimensional code and destroy the two-dimensional code

[0006] The common defect of the above three technologies is that the anti-counterfeiting carrier can be transferred as a whole for secondary use.
