Anti counterfeiting packaging: application prospect of laser holographic image technology

the application of laser holographic image technology in anti-counterfeiting packaging is mainly to print anti-counterfeiting trademarks. In addition to its general anti-counterfeiting function, the anti-counterfeiting trademark has the outstanding advantage of excellent decorative effect. Therefore, many enterprises are willing to use the anti-counterfeiting trademark of laser hologram

the main factors affecting the anti-counterfeiting performance of laser holographic trademarks are the types of trademarks and the use position of trademarks. Different kinds of laser hologram anti-counterfeiting trademarks have different anti-counterfeiting effects. Even the same kind of anti-counterfeiting trademarks have obvious differences in anti-counterfeiting effects due to different use positions

I. types of laser holographic image counterfeit trademarks

1. Self adhesive type

self adhesive type laser holographic image counterfeit proof trademarks are very convenient to use and have good adaptability to labeling machinery. Due to different glues and other adhesives, they will not show stains when used on the production line, especially for the packaging of high-grade hair. This trademark is also the most used at present. However, it has a fatal disadvantage that it can be used repeatedly. After being removed from the lower position, it can be completely glued to another position, so that some outlaws can make use of the old packaging and trademarks, thus affecting the anti-counterfeiting effect. From the perspective of anti-counterfeiting, such trademarks should not be used as anti-counterfeiting trademarks

2. Anti uncovering type

the development of anti uncovering type laser holographic image anti-counterfeiting trademark makes up for the defects of self-adhesive type laser holographic image anti-counterfeiting trademark. It can only be used once, and when it is removed from the package, the image on it is beyond recognition and cannot be used again. At present, many enterprises have been developing anti-counterfeiting trademark of anti uncovering laser holographic image, which is the most promising anti-counterfeiting trademark in the packaging field

3. Hot stamping type

hot stamping type laser holographic image anti-counterfeiting logo is a laser anti-counterfeiting logo that can not be removed at all, but we have achieved the trademark, which can be firmly and completely adhered to the package and integrated with the package. If the bonding position can be reasonably selected, its anti-counterfeiting effect will be better than the above two types of anti-counterfeiting effects of steel pipe and forged steel

to understand the characteristics of the hot stamping laser holographic logo, it is necessary to understand the manufacturing process of the logo. The process is mainly divided into three steps:

(1) making laser holographic plates. This is one of the key technologies for the production of hot stamping laser holographic marks. The production method is basically the same as that of ordinary laser holographic plates. It is mainly realized by laser twice imaging technology and post-processing technology

(2) make holographic electrochemical aluminum foil, which is the carrier of hot stamping image. Ordinary hot stamping electrochemical aluminum is mainly composed of base layer, thermal layer, coloring layer, aluminum plating layer and adhesive layer

all anodized aluminum used for hot stamping laser holographic identification is basically the same as that used for ordinary hot stamping, but the basic layer of hot stamping laser holographic anodized aluminum is molded laser hologram, and there is no coloring layer

(3) making hot stamping laser holographic signs. By using the bronzing machine with positioning system, the anodized aluminum with holographic image can be hot stamped on the printed matter or package, so that the holographic logo can be integrated with the printed matter and package, so as to complete the production of holographic logo. The logo can be a separate trademark pattern or a pattern matching the packaging pattern

the hot stamping laser holographic logo is easy to use, has many styles, and also has a certain decoration effect. It is suitable for hot stamping on paper, plastic, plexiglass and other packaging materials. In particular, it is closely combined with various materials and can not be torn off. It has excellent anti-counterfeiting effect

there are many ways to use hot stamping laser holographic marks. The anti-counterfeiting effect is different with different methods. The best anti-counterfeiting effect can be achieved only by reasonably selecting according to the packaging design requirements

4. Encrypted laser holographic image anti-counterfeiting trademark

it is feasible to encrypt the laser holographic image anti-counterfeiting trademark to greatly enhance the anti-counterfeiting effect. At present, the encryption methods used mainly include image blur processing method, moire fringe method, Fourier transform spectrum method, encryption method and so on. The use of these encryption methods has greatly improved the technical content of the anti-counterfeiting trademark of the laser holographic image. Among them, the encryption methods are highly unrecognizable and can achieve the purpose of anti-counterfeiting

II. Use position of laser holographic image anti-counterfeiting trademark

the use position of laser holographic image anti-counterfeiting trademark has a great impact on the anti-counterfeiting effect. Different positions have different anti-counterfeiting capabilities. Now take the anti-counterfeiting of bottle packaging as an example to analyze

the above two methods of pasting (hot stamping) anti-counterfeiting trademarks of laser holographic images can not meet the requirements of anti-counterfeiting. The reason is that these two methods can reuse the old laser hologram anti-counterfeiting trademark without damage, and can not prevent criminals from using the old packaging bottle to make counterfeits, thus losing the anti-counterfeiting purpose of the anti-counterfeiting label. Therefore, it can be said that if the pasting (hot stamping) position of the anti-counterfeiting trademark of the laser holographic image cannot be correctly selected, it is meaningless to conduct in-depth research only from the trademark itself

is another pasting (hot stamping) method for laser holographic image anti marking, which pastes (hot stamping) the trademark on the joint between the bottle body and the bottle cap. When opening the bottle cap, first touch the anti-counterfeiting trademark of the laser holographic image. If the trademark is anti uncovering, the laser holographic image on it will be destroyed when it is uncovering, which greatly reduces the possibility of reuse of the trademark and has a good anti-counterfeiting effect

to sum up, different kinds of laser hologram anti-counterfeiting trademarks can get better anti-counterfeiting effect only by adopting Xiangqing's pasting (hot stamping) method and selecting appropriate pasting (hot stamping) positions for different packages. Therefore, the development and production of anti-counterfeiting trademark is only the first step of anti-counterfeiting packaging, and the correct use is the key to anti-counterfeiting packaging

III. application prospect of laser holographic image technology in the field of anti-counterfeiting packaging

1. Application prospect of using encryption method to improve the anti-counterfeiting trademark of laser holographic image

it is an indisputable fact that the anti-counterfeiting trademark of laser holographic image is often counterfeited. Therefore, some people in the industry have put forward laser holographic image technology with higher technical content, hoping to improve its anti-counterfeiting effect. Is this effort effective and worthwhile? We can get a clear answer by looking at the degree of making the anti-counterfeiting trademark of the laser holographic image

Figure 4 shows the manufacturing process of laser holographic image anti-counterfeiting trademark. In the figure, links 1 and 2 are the picture production part of the anti-counterfeiting trademark of the optical holographic image, and links 4 and 5 are the production and use part of the anti-counterfeiting trademark of the laser holographic image. Connecting these two parts is the third link - the key to the anti-counterfeiting trademark of the laser holographic image. Because there is a master, the anti-counterfeiting trademark can be produced in large quantities

anti counterfeiting packaging is a systematic project, and every link may become the target of attack by outlaws. Among the five links in Figure 4, 3 and 5 are the weak links in anti-counterfeiting at present. Here, we will discuss session 3 first

there are many ways to obtain the master, which can be made according to the general process flow (as shown by the solid line in Figure 4) or forged directly according to a laser hologram anti-counterfeiting trademark (as shown by this line in Figure 4). It can be seen that no matter how complex the encryption measures are, they can not play a great role in anti-counterfeiting, because these encryption measures are carried out before the master is made and can be reflected on the trademark

the theft of the master plate is also a major aspect that leads to the loss of the anti-counterfeiting ability of the laser holographic image. This can only be prevented by strengthening the management of relevant enterprises. Before and after the printing of the trademark, the trademark using enterprises should properly keep the master plate of the trademark. Conditional enterprises should adopt the method of printing in different places or the method of making plates in factory a and pressing in factory B to minimize the chance of the master plate being stolen. In addition, the trademark printing enterprises should also strengthen the management of weak versions and finished product trademarks, so as to ensure that the interests of the chamber of commerce using enterprises will not be damaged

the production process of the anti-counterfeiting trademark of the laser holographic image determines that the ideal anti-counterfeiting effect can not be achieved through the encryption method. Only by improving the production process and technology of the anti-counterfeiting trademark can the encryption method achieve the anti-counterfeiting effect. So how can we improve the anti-counterfeiting ability of laser hologram anti-counterfeiting trademark? Link 4 is discussed below

2. Online production is a good way to prevent the theft of anti-counterfeiting trademarks

link 4 is the key procedure for mass production of anti-counterfeiting trademarks. Counterfeiters can obtain the cheap trademarks produced in large quantities through illegal means to implement commodity counterfeiting activities. If the machine can be improved or new equipment can be developed to realize direct online printing and pasting on the commodity packaging production line, most counterfeiters will give up counterfeiting because they are unable to buy expensive large-scale production lines

judging from the current technical situation, online production is still facing some difficulties. There is a problem with the equipment for engagement. If appropriate equipment is available, online production may be realized. From the point of view of the manufacturing process of holographic identification, it is possible to realize on-line manufacturing. In terms of the type of laser holographic identification, hot stamping laser holographic identification is the anti-counterfeiting holographic identification that most meets the requirements of on-line production

3. Combined with other anti-counterfeiting means

at present, the laser holographic trademark is used alone on the packaging for anti-counterfeiting. Its technical content gradually decreases with the passage of time, and its anti-counterfeiting ability is getting lower and lower. Only when it is combined with other technologies, can the overall anti-counterfeiting effect of the trademark be improved by increasing the manufacturing difficulty or using complexity of the laser holographic internal standard and absorbing the advantages of other technologies

after the package is wrapped by the heat shrinkable film, the anti-counterfeiting trademark is hot stamped on the heat shrinkable film. When opening the package, the heat shrinkable film will be torn, and the anti-counterfeiting trademark stamped on it will not be reused, so the purpose of anti-counterfeiting is achieved

generally, the area of the laser holographic logo is small, and the temperature it can withstand is limited. The thermal imprinting may damage the integrity of the holographic image and affect the decoration effect of the whole package. The way to solve this problem is to enlarge the edge area of the holographic image, and only the edge part of the image is stamped without touching the image area. This not only protects the rubber, but also implements the imprinting. Of course, the anti-counterfeiting trademark can also be used, which can also achieve the purpose of anti-counterfeiting

if some comprehensive technologies can be handed over and directly implemented in the production line of commodity packaging, better anti-counterfeiting packaging effect will be achieved. Of course, the development of corresponding equipment will also cost a lot of money, but from the current situation in the coming year, the larger equipment investment may be the best anti-counterfeiting expenditure, which can achieve the best anti-counterfeiting effect

laser holographic image technology is used in packaging to prevent 5.8pct of ring to ring ratio from falling. It is difficult for a single technology and method to achieve the anti-counterfeiting effect. With the continuous development of science and technology, other high-tech and laser holographic image technology can be integrated through various processes to increase the difficulty of imitation and achieve better anti-counterfeiting effect. It is the best way for laser holographic image technology to play an anti-counterfeiting role
