How Does Laser Technology Realize Anti-counterfeiting of Packaging?

Mar 23, 2020

Fake and shoddy products can be said to be cancer in the market, which not only greatly reduces the direct economic benefits of the enterprises being counterfeited, but also harms the vital interests of consumers. With the development of science and technology, forgery technology has put forward higher requirements for anti-counterfeiting technology.

It is the most popular anti-counterfeiting means to make an anti-counterfeiting mark by using holographic printing technology and attach it to the surface of the package. The holographic image has high technical content because of the integration of the latest achievements of laser, precision machinery, physical chemistry, and other disciplines. For most small-batch forgers, it is difficult to master a complete set of manufacturing technology and purchase manufacturing equipment. Therefore, the effect of this technology is significant. However, the embossed hologram anti-counterfeiting mark has not fully achieved its due function, and even there are forged marks.

Then came the new packaging materials with anti-counterfeiting function and the higher-level holographic image identification technology. The holographic image technology with better anti-counterfeiting function includes high-quality panchromatic true three-dimensional holography, complex dynamic holography, encrypted holography, digital holography, special hologram carrier technology (such as hologram special stamping material).

Laser anti-counterfeiting packaging materials

After laser processing, the material has the functions of anti-counterfeiting and decoration, which changes the local anti-counterfeiting mode of a laser hologram identification, and achieves the overall anti-counterfeiting effect. The whole package is treated by laser, plus the name and trademark of the manufacturer. It is a large area of main anti-counterfeiting, and the counterfeiter can't start. In addition, the laser packaging materials present seven colors and printing patterns under the light, with a bright appearance. The strange optical effect adds a new, strange, and beautiful feeling to the packaging.

Laser coding

Laser coding is mainly used to print the production date and product batch number of the package and anti-counterfeiting is not its primary function. Because of the high cost of laser encoder, it can only be used in mass production or other occasions where printing methods can not be realized, 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 shall be carried out at the joint between the cover and the container so that the upper half of the glyph is printed on the cover and the lower half is printed on the container.

The anti-counterfeiting function of this technology is that the packaging container cannot be reused. The new lid matches the old container and the handwriting is difficult to align; the laser is expensive and is encoded and typed on the production line. It is difficult for counterfeiters to invest a large amount of money to purchase 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 perspective of the anti-counterfeiting effect, laser coding technology is no worse than laser holographic image technology. The laser hologram logo is printed by the printing factory. The manufacturer using the logo can not ensure that the master plate does not flow out of the printing process or copy illegally. The price of a laser coder is expensive, and it must be used online. In addition, the hidden nature of changing the font template makes it difficult for those scattered small and medium-sized factories to make counterfeits.
