Since the outbreak of the epidemic, masks and forehead thermometers have become daily necessities at this stage. However, the huge demand gap has caused some illegal vendors to take advantage of it, and a large number of low-quality masks have flowed into the market. Terms related to "fake masks" and "mask fraud" have repeatedly appeared in hot searches. Fake masks not only have no protective effect, but they are also at risk of contamination due to poor production environment hygiene, which is extremely harmful to personal health. The most direct way to identify genuine and fake masks is to check the laser anti-counterfeiting marks.


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


Forehead temperature guns, usually print LOGO on the plastic shell, the effect of laser engraving by the ultraviolet laser marking machine is not hand-feeling, and the font will not be yellow due to scorching, which can reflect the brand's grade, and the price of the ultraviolet laser marking machine Compared with fiber laser marking machine, it is higher, so it can reduce the probability of being counterfeited and play a role of anti-counterfeiting.


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


Why is 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, and the surface material is instantly vaporized or changed in color by focusing, and the path of the laser on the surface of the material can be controlled to form the required permanent image. Text mark. Since laser marking can produce various characters, symbols and patterns, and the size of characters can range from millimeters to micrometers, this has special significance for the anti-counterfeiting of products, so it has a wide range of applications in the anti-counterfeiting market.


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


In addition to the features mentioned above, the marking of medical devices and drugs also has some special requirements. For example, for common pills and soft capsules, lithographic printing will produce pressure on the product, and non-contact laser marking will not deform the capsule, and can mark even more minute information on the tiny pills. On the medical equipment represented by stainless steel surgery and dental equipment, the laser can mark the absolutely smooth surface, which can prevent bacteria from sticking to the surface, and the marked surface will not damage the corrosion-resistant chemical passivation treatment , Can make the anti-corrosion coating exist even after several years of use and countless times of cleaning and disinfection.


In fact, laser marking anti-counterfeiting technology can not only be used to identify the authenticity of masks, but also play 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 all aspects of our lives.
