Since 2019-nCoV outbreak, masks have become necessities at this stage. However, the huge demand gap has caused some unscrupulous traders to take advantage of it, and a large number of inferior masks have flowed into the market. Entries related to "fake masks" and "mask scams" have repeatedly appeared in hot searches. Fake masks not only have no protective effect, but also have the risk of being contaminated because the production environment is not up to standard, which is extremely harmful to personal health. The most direct way to identify genuine and fake masks is to look at the laser anti-counterfeiting mark.
For boxed 3M N95 / KN95 series masks, they can be identified by the anti-counterfeit label on the mask packaging 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 discerned by observing the font on the masks. Really 3M mask text is marked by laser, the font is twilled, and the fake is printed by ink with dots (uneven ink marks).
Why lasers? Laser marking anti - counterfeiting features and application advantages.
The basic principle of laser marking is to use a high-energy-density laser beam to act on the surface of the material. By focusing, the surface material is instantly vaporized or the color changes. The path of the laser on the surface of the material can be controlled to form the required permanent map text mark. Because laser marking can produce a variety of characters, symbols and patterns, the character size can be on the order of millimeters to micrometers, which has special significance for product anti-counterfeiting, so it is widely used in the anti-counterfeiting market.
