Description

Graphic anti-counterfeiting label and manufacturing method thereof

Technical field

The invention belongs to the technical field of anti-counterfeiting, and in particular relates to a graphic anti-counterfeiting label and a manufacturing method thereof.

Background technique

Anti-counterfeiting technology is an interdisciplinary technology involving many fields such as optics, chemistry, physics, electromagnetics, computer technology, spectroscopy, digital printing technology, packaging and printing technology. For a long time in the past, anti-counterfeiting technology was only used on passports, certificates, currency, tickets and securities produced by banks, customs, taxation, finance, public security and other departments. With the rapid development of the market economy, merchants pay more and more attention to the protection of intellectual property protection, and require their products to have corresponding anti-counterfeiting functions. At the same time, due to the proliferation of counterfeiting and counterfeiting in China, the counterfeiting of pesticides, fertilizers, auto parts and other commodities in tobacco and alcohol, food, medicine, health care products, cosmetics, clothing, optical products and production materials is very serious, and the demand for anti-counterfeiting and anti-counterfeiting is very high. urgent. With the acceleration of China's marketization process, the improvement of national income, and the influx of international brands, controlling and combating counterfeiting and counterfeiting activities, and maintaining a good market competition environment, anti-counterfeiting technology plays an important role. Anti-counterfeiting technologies are diverse, such as laser holography, watermarking, code technology, digital coding, barcodes, QR codes, and RFID. Although the cost may be higher, in principle the labels used by these technologies can be copied, and the labels cannot be 100% guaranteed not to be copied. At the same time, the guarantee of the relationship between the label and the target is very important. Many anti-counterfeiting technology products are in the form of self-adhesive labels, which is very convenient for customers to make use. But the sticker has an Achilles heel, which can be removed and reused by the counterfeiters. Because in theory, any self-adhesive label can be uncovered and reused. It can be seen that the label itself cannot be copied and the label cannot be removed is a basic requirement for a good label. Although the bubble part of the Bubble Tag introduced by Prooftag in France is theoretically almost impossible to copy, the bubble part has no anti-explosion function, and the anti-detonation part is completely repaired or duplicated, resulting in the comprehensive reproduction of the tag. The sex is greatly reduced.

Existing anti-counterfeit labels may be re-used by being transplanted to other objects, and the label has low tamper resistance.

Summary of the invention

Step 1: When making the label, first prepare the lower layer of material;

Step two, coating a certain thickness of the underlying material with a weakly viscous glue, and then sprinkling the metal particles, graphite particles and the dye particles in a certain particle size range;

Step 3, covering a layer of the underlying material coated with the granules with a layer of the underlying material, and repeating steps 2 to 3 one to several times;

Step 5: Put the laminated structure into the heating device to control the heating power and time to ensure that the particles in the laminated structure absorb heat and generate heat, and randomly generate a diameter of 0.01 to 10 mm. Irregular bubbles;

In the embodiment of the present invention, the lowermost oil film paper of the label is first peeled off, and then the exposed super glue side is attached to the object to be anti-counterfeit.

Due to the randomness of the particle distribution in the functional layer, the self-rheing of the particles after absorption and the generation of surrounding bubbles are completely uncontrollable, so the label is non-reproducible.

When the product to which the security label is attached is used, the tearing tap is torn, resulting in irregular separation between the first material layer, the functional layer and the underlying material, and the pattern formed by the particles and bubbles located in the functional layer is destroyed, and the label is damaged. Can no longer be transplanted to other objects for reuse, improving the tamper resistance of the label.

When applying the label, first peel off the bottom oil film paper, and then attach the exposed super glue side to the object to be anti-counterfeit. Because the distribution of particles in the functional layer is random, and the particles self-flow after endothermic heat absorption and The generation of surrounding bubbles is completely uncontrollable, so the label is non-reproducible. When the product with the anti-counterfeit label is used, the tearing tap is torn open, resulting in irregular separation between the upper layer material, the functional layer and the underlying material, and the pattern formed by the particles and bubbles located in the functional layer is destroyed, and the label is damaged, and can no longer be used.
