Anti-counterfeit weapon of cigarette pack--holographic high-speed positioning anti-counterfeiting stamping foil

With the increasing number of counterfeit cigarettes and smuggled cigarettes, tobacco packaging is becoming more and more important. Tobacco companies are constantly seeking new types of anti-counterfeiting technologies and anti-counterfeiting products with high technical content, strong confidentiality, and non-reproducibility. Laser holographic technology has played an important role in protecting famous brands and cracking down on counterfeiting and counterfeiting. In the ongoing trials with fake and counterfeit counterfeit, laser holographic anti-counterfeiting technology has also made considerable progress, rapid replacement, holographic high-speed positioning anti-counterfeit stamping foil is one of them.

The development of holographic anti-counterfeiting technology in cigarette bag anti-counterfeit applications has undergone five processes of self-adhesive holographic anti-counterfeit identification, holographic compounding, holographic transfer, holographic hot stamping, and holographic positioning hollow positioning hot stamping.

At present, the holographic hot stamping process is the main method for applying holograms in large quantities, and it is even more so in the combination of security anti-counterfeiting and packaging printing. The hologram stamped on the substrate is very thin and integrated with the substrate. The hologram and the printing pattern and color on the substrate can be matched with each other to obtain a very good visual effect.

For holographic hot stamping, the medium for recording holograms is required to have a high resolution, usually capable of reaching 3000 line pairs/mm or more; it is also required that the imaging layer of the hologram hot stamp foil ensure that the information of the high resolution laser hologram is not lost. To ensure that the hologram after hot stamping still has a high diffraction efficiency.

According to the different hot stamping processes, holographic hot stamping can be roughly divided into three types, namely, low-speed holographic hot stamping, fast random holographic hot stamping and high-speed positioning holographic hot stamping. Among them, the high-speed positioning hologram hot stamping technology has the highest requirements and the greatest anti-counterfeiting efforts. It is necessary to ensure that the hologram is completely and accurately stamped at a specified position under high production efficiency, and the positioning accuracy cannot be lower than ±0.25 mm.

The production of fast positioning holographic hot stamping foil not only has certain requirements for the imaging layer, separation layer and hot melt adhesive, but also puts high requirements on the precision of the holographic hot stamping foil molding process and the separation process, so as to ensure the hot Imprint accurate positioning.

In accordance with the needs of the domestic market, China Industrial Technology Image Branch began to use laser holographic hot stamping technology for product packaging as a new direction of development since 1997, focusing on research and development of fast laser holographic positioning hot stamping materials. After two years of efforts, rapid response of the peeling layer material, hot melt adhesives and imaging layers with high diffraction efficiency have been developed to solve the problems of material preparation and production process, plus the advantages of the original laser holographic anti-counterfeiting technology. The company has successfully developed a laser holographic high-speed positioning hot stamping foil for the first time in China, becoming the first domestic supplier to supply such products in bulk. This made China occupy a place in this high-tech industry, and at the same time forced the importation of holographic positioning stamping foils to drastically reduce prices, thus saving costs for the domestic packaging printing companies that use holographic positioning hot stamping foils and making them more expensive. Profit space.

The “White Sands Golden Century” holographic positioning anti-counterfeiting stamping foil developed by HG Image won the annual International Best Security Award at the 1HMA (International Holographic Manufacturers Association) 2003 Annual Conference. This is the first item in China’s anti-counterfeiting technology product in recent years. International awards.

At present, holographic positioning hot stamping technology has been widely used in cigarette pack printing in China. It has truly played a dual role in anti-counterfeiting and decorating, and is also being gradually adopted by pharmaceuticals, high-grade daily chemical products and cosmetics packaging.

After the successful development of the holographic positioning hot stamping technology, China Labor Image has developed the Hollow Positioning Hot Stamping Technology and the Holographic Transparent Media Stamping Momo.

Using holographic hollow technology to etch a transparent pattern, pattern or text on the fixed position of the holographic hot stamp foil, and then hot stamping on the packaging, its exquisite effect is amazing, and it shows a special visual anti-counterfeiting. effect. The high technical difficulty makes counterfeiters stop.

On the basis of the successful development of laser holographic hot stamping foils, Huagong Image has further explored ideas and successfully developed a holographic transparent medium hot stamping film. The transparent hologram hot stamping film made of multilayer film structure has a very good overall effect. The pattern is clearer and brighter than the ordinary film, which meets the market demand.

After years of accumulation in technology development, the company already has photochemical relief technology, actinic relief encryption technology, actinic relief micro-techniques, one-time use of anti-counterfeiting labels, tamper-proof glue, anti-lifting holographic film, hollow signing technology, random hollowing No. technology, rapid positioning hot stamping foil, positioning hollow hot stamping technology, transparent hot stamping foil, dual encryption information anti-counterfeiting technology, hollow encryption code anti-counterfeit identification and many other unique anti-counterfeiting technology.
