The mainstream of the development of anti-counterfeiting packaging technology

fake and shoddy products can be said to be a cancer in the market. It not only greatly reduces the direct economic benefits of the counterfeit enterprises, but also endangers the vital interests of consumers. With the development of science and technology, the brilliance and universality of forgery technology have put forward higher requirements for anti-counterfeiting technology

the so-called "anti-counterfeiting packaging technology" is that it mainly targets commodities, which is not only an integral part of anti-counterfeiting, but also an integral part of packaging technology. Therefore, anti-counterfeiting packaging not only has the general functional characteristics of anti-counterfeiting technology, but also has its own characteristics suitable for commodity packaging

at present, there are many anti-counterfeiting packaging means, and there are only more than 100 anti-counterfeiting marks. However, from the overall analysis, anti-counterfeiting packaging technology focuses on the following aspects: anti-counterfeiting marks; Special material technology; Printing process; Packaging structure and other methods. The following technical means are in the mainstream

laser hologram uses holographic printing technology to make anti-counterfeiting marks, which are attached to the surface of packages. It is the most popular anti-counterfeiting means at present. Holographic image has high technical content because it integrates the latest achievements of laser, precision machinery, physical chemistry and other disciplines. For most small batch counterfeiters, it is difficult to master a full set of manufacturing technology and purchase manufacturing equipment. Therefore, the effect of this technology is remarkable. However, the molded holographic anti-counterfeiting logo did not fully achieve its due function, and even forged signs appeared

followed by new packaging materials with anti-counterfeiting function processed by laser holographic technology and higher-level holographic image identification technology. Holographic image technology with better anti-counterfeiting function includes: high-quality panchromatic true three-dimensional holographic technology, complex dynamic hologram technology, encrypted holographic technology, digital holographic technology, special hologram carrier technology (such as hologram special embossing material)

laser anti-counterfeiting packaging materials. The materials processed by laser have the functions of anti-counterfeiting and decoration, which changes the local anti-counterfeiting method marked by a piece of laser holographic image to achieve the overall anti-counterfeiting effect. The whole package is processed by laser, plus the manufacturer's name, trademark, etc., showing a large area of subject anti-counterfeiting, and the counterfeiters have no way to start. In addition, the laser packaging materials show colorful colors and printing patterns under the light, with a bright appearance. The strange optical effects add a new, strange and beautiful feeling to the packaging

there are four categories of laser processed packaging materials

① flexible packaging bag: laser film is made with high and new technology, then compounded with ordinary plastic film and printed to form a laser material flexible packaging bag (called laser flexible packaging bag)

② hard packing box: one is to produce laser film with high and new technology, and then compound it with cardboard, plus printing to form a hard box. The other is to print on the general cardboard box first, and then compound with the laser treated glazing film to form a glazing cardboard box

③ laser paper: laser paper is made directly on paper. The production process of laser paper is difficult and the cost is high. But its advantages are: easy to print, easy to handle, no environmental problems; Some products must be packaged in paper (such as cigarette boxes), especially suitable for cigarette boxes, bottle stickers, labels, tax slips, calendars, gift bags, etc. In order to increase the anti-counterfeiting effect, the manufacturer can use the special hologram from imitation to self renovation, which is always unconventional. The pattern logo is used as the paper base pattern, plus the product graphics, to make a unique special packaging paper

④ at present, there is also a kind of hot stamping foil treated by laser -- high-grade electrochemical aluminum products. The logo specially made with it can be displayed in multi-dimensional three-dimensional. Dynamic pictures can be designed by computer, and "light spots" can be reserved for encryption, so that the main pattern can display different patterns from different perspectives. This hot stamping foil is integrated with the package after it is combined with the surface of the package to achieve the dual effects of anti-counterfeiting and beauty. Invisible identification system biocode has successfully developed a new invisible identification system, which uses antibodies as a new material for making anti-counterfeiting identification. The system consists of two objects: the marker compound added to the product and the antibody used to identify the existence of the marker and make quantitative analysis if necessary. The marker compound can be a daily chemical, but it must be durable, inert, easy to mix with the product, and meet the requirements of health and regulations. These marks are usually mixed into the product in a small amount of a few percent. Antibodies are specific biometric molecules, and each antibody only recognizes or binds to a specific compound. There are two kinds of marker recognition operations: field measurement and laboratory testing. It can not only test the existence and accurate content of markers, but also detect the replaced or diluted products

surface stealth technology has the following advantages: specific graphics and positions are suitable for specific users; True invisibility; Both printed labels with markers can be used, and a set of customized inkjet system can be installed, High safety (because when there is no specific antibody, the marker cannot be seen, and the specific antibody is strictly controlled; the logo image can be erased and redisplayed. Compared with the hologram logo, the invisible anti-counterfeiting trademark has more vitality.

Stefano Domenicali, CEO of Lamborghini, attended the ribbon cutting ceremony. Laser coding is mainly used to print the production date and product batch number of packaging, and anti-counterfeiting is not its primary function. Due to the cost of the laser coder It is expensive and can only be used in occasions where mass production or other printing methods cannot be achieved, so that it can play a role in anti-counterfeiting packaging

laser coding sealing technology is a better anti-counterfeiting technology for containers. After the product is sealed and capped, laser printing is carried out at the joint between the cover and the container, so that the upper half of the font is printed on the cover and the lower half on the container. The anti-counterfeiting function of this technology is: packaging container B. capacity segmentation: 7 levels in the whole process: × 1 cannot be reused. The new cover matches the old container, and the handwriting is difficult to align; Lasers are expensive and are coded and typed on the production line. Generally, it is difficult for counterfeiters to invest a large amount of money to buy this equipment; The manufacturer can change the printing template at will, and use different templates on different dates. Only a few people know the details of the replacement, which is difficult for outsiders to crack. From the anti-counterfeiting image source: biocatalysis results, laser coding technology is not inferior to laser holographic image technology. The laser holographic logo is printed by the printing factory, and the manufacturer using the logo cannot ensure that the master will not flow out of the printing process or be copied illegally. Laser coders are expensive and must be used. Coupled with the secrecy of changing font templates, it is difficult for scattered small and medium-sized factories to make fake ones. Gravure printing anti-counterfeiting gravure printing carries ink in pits carved according to the original text. The thickness of lines and the thickness of ink can be controlled during engraving, which is not easy to be imitated and forged, especially the depth of ink pits. The possibility of realistic carving based on printed graphics and texts is very small. Due to its anti-counterfeiting effect, gravure printing has been increasingly promoted to enterprise trademark and packaging and decoration printing

the anti-counterfeiting advantage of gravure printing is that manual engraving gravure can implement secret anti-counterfeiting methods. It is particularly effective to allow the substrate with high plate making cost to adopt manual engraving for plate making with small printing volume. Counterfeiters who pursue short-term interests may not be willing to take this investment risk; Plate making and printing are carried out in different places. Try to separate the two working links of plate making and printing, so that the fewer people who know the core content of the whole trademark (or securities) printing work, the better. Of course, attention should also be paid to prevent the theft of printing plates and printed materials; It can be combined with anti-counterfeiting ink technology and adopts a unique special ink. Its composition, particle fineness and additives are kept confidential to the outside world. Even if the printed matter has a unique effect, it has the function of secret anti-counterfeiting
