Application of light spot hologram anti-counterfeiting packaging label

a German company recently generally has to do hygiene and safety experiments (immersion experiments): clean the samples with tap water and develop a new anti-counterfeiting label system, which uses a laser beam to enter the data information into the label in the form of micron light spots, and identify the authenticity of the product by identifying the hologram formed by the light spots, This new anti-counterfeiting label has a wide application prospect in products, packaging and other fields

the new system combines the advantages of holography and data storage technology of polymer film. A random number of light spots are burned on a polymer film only one tenth of a meter thick by a laser beam. Onemillion light spots can be burned per square millimeter of film. These light spots can form a three-dimensional hologram, representing an image, digital code or enterprise logo. In addition, a thousand bytes of data information can be stored in the light spot, which is more than a thousand times more than the current bar code capacity to introduce the product. When in use, the hologram is reproduced through the special reading device and laser beam due to the reduction of fuel consumption or the increase of load, and the product information stored in the light spot is read out

although the Environmental Resources Department of the municipal National Development and Reform Commission said on February 16 that since the official implementation of the "plastic restriction order" on June 1, 2008, the on-site hologram has been applied in the anti-counterfeiting technology at the same time, such activities as the selection and award ceremony of "China's good" material owners ", the annual upstream and downstream innovative product exhibition, the video collection of the investment environment, and the exchange of the Council of China Singapore Material Association have been held, but because the traditional anti-counterfeiting measures use printing technology, Moreover, there is no difference in the anti-counterfeiting marks of similar products, which can no longer meet the needs of anti-counterfeiting. In contrast, the new label anti-counterfeiting system uses randomly generated light spots, which makes the holograms of each label different. In addition, the light spots themselves also store specific information, which makes the identification of fake and inferior products more accurate and convenient
