Application of anti-counterfeiting technology in packaging

anti counterfeiting technology is an interdisciplinary subject involving optics, chemistry, physics, electromagnetism, computer technology, spectrum technology, printing technology, digital technology, packaging technology and many other fields. The commonly used anti-counterfeiting technologies include anti-counterfeiting ink, anti-counterfeiting paper, anti-counterfeiting self-adhesive, miniature text printing, special anti-counterfeiting printing of bills, safety wire, encryption technology, laser holographic transfer paper technology, positioning hot stamping, code anti-counterfeiting, atomic nuclear double card anti-counterfeiting technology (nuclear track), texture anti-counterfeiting identification technology, packaging printing plate making anti-counterfeiting technology, manual engraving gravure printing, etc

paper based anti-counterfeiting technology

comprehensive paper-based anti-counterfeiting technology is widely used in product trademarks, logos, packaging and tickets. First, in the papermaking process, special processes and equipment are used to add watermarks, and safety wires or fluorescent fibers are added according to user requirements. Among them, the security line anti-counterfeiting paper can also be pre processed by micro text printing, fluorescent color printing, colorless fluorescent ink printing, gold silver black printing, invisible buried colorless fluorescent printing, etc. Fluorescent fibers include color, colorless long and short waves, etc

anti counterfeit holographic logo positioning hot stamping technology

positioning hot stamping technology is very difficult, which requires packaging and printing manufacturers to have expensive precision positioning hot stamping equipment; It is required that other printing related supporting equipment of the printing plant can meet the requirements of positioning hot stamping, and have precise walking and positioning effects; The process requirements for special equipment and raw materials are very high. All the anti-counterfeiting technologies used on the general holographic anti-counterfeiting adhesive label can be used on the hot stamping label, such as pixel holography, true color, synthetic encryption, micro lithography, photochemical relief and other technologies, which can play an excellent anti-counterfeiting effect. Positioning hot stamping is organically integrated with the packaging box itself, which complements other anti-counterfeiting technologies, and the design can also greatly improve the decoration effect of packaging. Positioning hot stamping can realize high-speed large-scale automatic production, which is matched with high-speed printing equipment, and meets the production process requirements of printing manufacturers. In addition, since the plastic film is not covered after hot stamping, it can meet the requirements of green environmental protection packaging, which is a big step forward than the existing self-adhesive holographic anti-counterfeiting logo, and completely solves the problem of repeated use of anti-counterfeiting logo

laser holographic transfer paper technology

laser holographic transfer paper is a new material for anti-counterfeiting packaging and printing. It organically combines a number of technologies from different disciplines, such as laser holographic molding, computer lithography, special plate making, precision electroforming, fine chemical industry, high-precision stripping, and so on. First, it is made into a transferable holographic plastic film, and then it is transferred to the paper to make a laser holographic transfer paper

laser holographic anti-counterfeiting marking technology pasted by full-automatic labeling machine

this technology is to paste laser holographic anti-counterfeiting marking by full-automatic labeling machine after printing on plastic film, and then compound, cut and make bags. This anti-counterfeiting logo is pasted between the two layers of film rather than on the surface, and its width is 115mm. It is pasted faster by machine, eliminating manual pasting, not easy to counterfeit, and has a good anti-counterfeiting effect. In this anti-counterfeiting technology, only holographic anti-counterfeiting disk label has applied more than ten superposition technologies, such as micro engraving encryption, dynamic recursive image processing, computer creative light variable graphics, silk simulation, computer-controlled mosaic, holographic multi-channel, implicit anti-counterfeiting, invisible encryption, 90 degree control, fluorescent anti-counterfeiting, etc., with high technical content. At present, this technology has been widely used in the anti-counterfeiting of the outer packaging of famous and high-quality goods in China

from a technical point of view, it meets the international requirements for five comprehensive indicators of anti-counterfeiting packaging technology. It is the best form of anti-counterfeiting of plastic packaging at present, including instant effectiveness, aesthetics, recognition, versatility and economy. From the use effect, it not only improves the anti-counterfeiting technology level of plastic packaging and printing, but also enriches the anti-counterfeiting methods of packaging materials in China and improves the anti-counterfeiting performance of packaging materials

anti counterfeiting technology based on ink

the so-called anti-counterfeiting ink is a special printing ink processed by adding anti-counterfeiting materials with special properties to the ink binder. From the perspective of the anti-counterfeiting functions realized by the products, the anti-counterfeiting inks widely used at present include the following 10 categories: UV fluorescent inks, Huaibei multi-point efforts to promote the development of ceramic aluminum new material industry, solar laser color changing inks, thermal anti-counterfeiting inks (thermochromic inks), reactive color changing inks, homochromatic heterospectral inks, intelligent anti-counterfeiting inks, multi-functional or comprehensive anti-counterfeiting inks (laser holography plus fluorescent anti-counterfeiting inks, heterochromatic inks with corners), etc

temperature change inks can change color under the action of heat, which is usually divided into reversible and irreversible thermal main color anti-counterfeiting inks. Generally, the color change temperature refers to that the color change effect can occur under the action of Celsius temperature. The principle of heat reforming color is to make the discolored compound change physically or chemically under the condition of heating, resulting in its own light absorption change

nuclear double card (nuclear track) anti-counterfeiting technology

nuclear double card anti-counterfeiting technology is a micro anti-counterfeiting technology that can directly penetrate into various carriers. Its principle is to use the randomness, computerization and extension characteristics of nuclear groups in the movement process to embed them in various carriers in a layered and three-dimensional manner, which sets insurmountable obstacles for imitators, and even the producer himself cannot copy the same nuclear track original

its main characteristics: uniqueness; Appearance recognition; Detectability; Irreversibility; The price is moderate and easy to use

has a wide range of applications and can be used on laser holographic films; It can be used on all kinds of paper; It can be used in various plastic films; It can be used in train tickets and ship tickets

texture anti-counterfeiting identification technology

the "texture anti-counterfeiting identification" developed by Oriental International anti-counterfeiting center is a texture anti-counterfeiting identification made of paper-based as the carrier and colored fibers added to the paper. Its feature is that the texture formed by the fiber is easy to be tested by needle picking method, and the imitation ink can be simply distinguished; The fiber texture is clear, the shape is complex, and it is easy to fall off; It is not easy to imitate textile fabrics by manually burying or pasting fibers

its technological process is:

select three-dimensional, random, structural, clear, unique and difficult to copy structural texture carrier materials as anti-counterfeiting features; Encode the texture anti-counterfeiting marks so that each mark has at least one unique code containing random numbers belonging to it; Printing coordinates, tables, position serial numbers and other references used to accurately describe the texture position; The texture anti-counterfeiting feature information is photographed and collected, numbered and registered, filed and warehoused; The texture anti-counterfeiting feature information database is accessed, interconnected and other public information

texture anti-counterfeiting logo highlights the defects that traditional anti-counterfeiting products are easy to be counterfeited in batches and difficult to identify by consumers, and creatively solves the contradiction between easy identification and difficult imitation of anti-counterfeiting technology

the texture anti-counterfeiting logo can be queried and identified by, fax or computer through this authentication network system, which can be checked first and then bought. Consumer recognition is convenient, simple, intuitive and accurate. Therefore, it can be said that the texture anti-counterfeiting logo query system is a high-tech product grafted with the ancient "tiger symbol" anti-counterfeiting principle and digital new technology. According to the PCT international search report, texture anti-counterfeiting is the first case in China. It has the characteristics of simple and reliable anti-counterfeiting principle, high imitation cost, unprofitable counterfeiters, long anti-counterfeiting cycle and so on

code anti-counterfeiting technology

taking the anti-counterfeiting technology of anti-counterfeiting markers of China Commodity anti-counterfeiting network system project as an example, China anti-counterfeiting network system project is a national key scientific and technological innovation project running on the platform of "Chinatelecom 168315 enterprise room service center". The project is a high-tech socialized anti-counterfeiting system for commodity anti-counterfeiting by comprehensively using computer, network communication, information password, high-tech inkjet printing technology and modern management technology

a 17 digit information anti-counterfeiting code is printed on the logo of China's commodity anti-counterfeiting network system. The code of each commodity is different, which is equivalent to giving a specific "ID card" number to the commodity every year. Consumers only need to input the code through Internet, SMS, 168, etc. to quickly identify the authenticity of the product. In addition, engraving intaglio printing anti-counterfeiting technology (printing banknotes, stamps, etc.), printing plate making anti-counterfeiting technology, etc. are also anti-counterfeiting technologies applied to packaging products, which are not listed here

laser holography and other comprehensive anti-counterfeiting technologies

laser holography technology is a modern laser application technology achievement that has attracted widespread attention at home and abroad in recent years. It is favored and loved by consumers with its holographic imaging principle and colorful flash effect

take Shenzhen Jinjia company as an example. At present, the company has developed, designed and printed hundreds of brands of high-quality cigarette packs for more than 50 cigarette factories in China, and has adopted many advanced processes on these products (such as logical light grain, gravure sand printing and PS banknote printing, multi beam laser holography, computer digital coding magnetic anti-counterfeiting technology, D4D anti-counterfeiting technology, transfer gold, silver paperboard printing, three-dimensional holographic printing, etc.), For example, "Honghe 88" and "Honghe 9" produced by Yunnan Honghe tobacco factory not only need a variety of valve types 9 "soft pack cigarette style, but also are produced by jieras em410 narrow width wheel transfer brush machine, which integrates multiple functions such as laminating, printing, UV glazing, printing, hot stamping, concave convex, die cutting, waste discharge and so on. The characteristics of this kind of flexible packaging are reflected in that the product not only retains the rainbow, refraction and high-end characteristics of materials such as laser anodized aluminum paper and anti-counterfeiting film (holographic film), but also has better point level and spot color ink than traditional printing. The product is completed by paper at one time

Shandong Zibo Taibao laser anti-counterfeiting Co., Ltd. also uses flexographic printing to combine with a variety of anti-counterfeiting technologies (such as double card interference pattern technology, fluorescent ink printing, laser transfer film technology, laser rainbow scratch anti-counterfeiting packaging technology, inlay technology, coin pattern technology and microfilm technology, anti-counterfeiting digital search technology, etc.), and produces anti-counterfeiting trademark labels and anti-counterfeiting packaging products for many enterprises. For example, the packaging cartons of Banlangen, Ganmao granule, bezoar, snake gall, Chuanbei liquid and other products of kongfu pharmaceutical factory; Antipyretic oral liquid box produced by Weifang Tianyang Pharmaceutical Co., Ltd. These have high anti-counterfeiting performance and are welcomed by customers

in recent years, although China's anti-counterfeiting technology has been greatly developed and improved, it still lags far behind the current market needs. At present, the counterfeit products of packaging and printing in the world are growing at a rate of 20% every year, while the anti-counterfeiting products are only growing at about 8% every year, and there are few anti-counterfeiting technologies with high technical content, so the current situation is still very serious
