Since the outbreak of the epidemic, masks and forehead thermometers have become necessities of life at this stage. However, the huge demand gap has allowed some illegal vendors to take advantage of it, and a large number of low-quality masks have flowed into the market, and entries related to "fake masks" and "mask fraud" have repeatedly appeared in hot searches. Fake masks not only have no protective effect, but also have the risk of contamination due to substandard production environmental 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 hygiene, so the requirements for product marking are very high, and information such as production date and instructions for use must be permanent. Therefore, we will choose laser marking machines as processing signs. Non-inkjet printer, silk screen and other traditional methods.
Forehead temperature guns usually print LOGO on the plastic shell. The laser engraving effect of the UV laser marking machine has no hand feeling, and the font will not be yellow due to scorching, which can reflect the brand's grade, and the price of the UV laser marking machine Compared with the fiber laser marking machine, it is higher, so it can reduce the chance 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 with ink with dots (marks of uneven ink).
