How to distinguish a genuine 3M mask from a fake one? According to the 3M mask anti-counterfeiting guide released by 3M China on its official Weibo, the authenticity of masks can be identified by scanning the two-dimensional code on the packaging box through wechat or observing the anti-counterfeiting logo on the packaging box.
In addition, if you buy a 3M mask in bulk, you can also identify it by looking at the printed information of the mask. 3M masks are all marked by laser, and the information never falls off. The marking marks are at a 45 degree oblique angle. Fake products are printed with ink, and the color will fade when wiped with liquid medicine. There are often uneven ink marks, blank spots in the handwriting, and no 45 degree printing marks can be seen at all.
The brand-new, environmental friendly and good anti-counterfeiting laser marking process is widely used in mask label marking. As the righteous messenger of mask anti-counterfeiting safety, the laser marking machine uses a high-energy continuous laser beam to instantaneously melt and even vaporize the surface material. By controlling the path of the laser on the surface of the material, it forms a never falling identification code on the outer layer of the mask. Any liquid medicine wiping will not work, Help mask product anti-counterfeiting and whole process traceability.
