High power solid state UV laser facilitates anti-counterfeiting traceability of masks and forehead thermometers

Since the outbreak of the epidemic, masks and forehead thermometers have become necessities of life at this stage. However, the huge demand gap has made some unscrupulous traders take advantage of it, and a large number of inferior masks have entered the market. Fake masks not only have no protective effect, but also have the risk of contamination due to substandard production environment hygiene, which is extremely harmful to personal health. To identify real and fake masks, the most direct way is to check the laser anti-counterfeiting marks.

First of all, the pharmaceutical and medical industries attach great importance to safety and hygiene, so the requirements for product marking are very high, and information such as production date, instructions for use and other information must be permanent, so we will choose laser marking machine as the processing mark, and Non-jet printer, silk screen printing and other traditional methods.

Forehead temperature guns generally print LOGO on the plastic shell. The effect of laser engraving by UV laser marking machine has no feel, and the font will not turn yellow due to scorching, which can reflect the grade of the brand, and the price of UV laser marking machine Compared with the fiber laser marking machine, it is higher, so it can reduce the probability of being counterfeited and play an anti-counterfeiting role.

For boxed 3M N95/KN95 series masks, it can be identified by the anti-counterfeiting label on the mask box. The labels of real masks will change color from different angles, while the labels of fake masks will not change color. For bulk 3M N95/KN95 series masks, the authenticity can be identified by observing the fonts on the masks. The real 3M mask text is marked by laser, and the font has twill, while the fake is printed by ink and has dots (traces of uneven ink).

Why laser: the characteristics and application advantages of laser marking anti-counterfeiting

The basic principle of laser marking is to use a high-energy-density laser beam to act on the surface of the material, to instantly vaporize or change the color of the surface material by focusing, and to form the required permanent image by controlling the path of the laser on the surface of the material. Text mark. Since laser marking can print various characters, symbols and patterns, the size of the characters can be from millimeters to micrometers, which has special significance for the anti-counterfeiting of products, so it is widely used in the anti-counterfeiting market.

Before the large-scale application of laser marking, the marking on packaging was usually printed with ink. The marks printed by this traditional method tend to peel off over time, become blurred, easily tampered with, and cannot be used with high precision. Although it has advantages in equipment cost, the continuous cost of consumables (ink) is high, and it will cause some pollution to the environment.

Taking the most common food packaging as an example, because the marks printed by traditional methods are easy to erase and fall off, some criminals will print some expired or even counterfeit products with brand trademarks, or modify the production date to make these substandard products. circulated in the city. Such phenomena are common in the fields of grain and oil, beverages, snacks, sauces and so on. In addition, for some paper food packaging, the harmful substances of ink may penetrate the packaging and contaminate the food, posing a threat to the health of consumers.

The emergence of laser technology has solved a series of problems brought by traditional ink printing. For food packaging, the use of laser marking has the advantages of non-toxic, non-polluting, high efficiency, high definition, exquisite patterns, and never falling off. In addition, laser marking can also be combined with computer technology, and by linking to the database system, we can track and query the detailed information of the factory and circulation of food in time to ensure that we can eat with confidence.

The medical industry is inseparable from the escort of laser marking. Since medical products are in direct contact with the human body, it is related to the life and health of the people, so the prevention of counterfeiting and anti-counterfeiting of medical products has become the top priority of protecting the health and safety of consumers.

In addition to some of the characteristics mentioned above, the marking of medical devices and drugs also has some special requirements. For example, for common pills and soft capsules, if lithographic printing is used, the product will be stressed, while non-contact laser marking will not deform the capsule, and can mark smaller information on tiny pills. On medical devices such as stainless steel surgical and dental equipment, the laser can mark absolutely smooth surfaces, which prevents bacteria from sticking to the surface, and the marked surface does not damage the corrosion-resistant chemical passivation treatment , allowing the anti-corrosion coating to persist even after years of use and countless cleanings and sterilizations. Another example is the 3M mask mentioned at the beginning, whether there is a laser mark is an important sign to distinguish the authenticity.

In fact, laser marking anti-counterfeiting technology can not only be used to identify the authenticity of masks, but also plays a huge role in packaging anti-counterfeiting and traceability in the fields of food, medicine, tobacco, beauty, and electronic products. It can be said that laser marking Anti-counterfeiting has been integrated into every aspect of our lives.
