355nm UV laser marking food can not be wiped for a long time

We all know that the application of laser marking machine in 3C electronic products has been covered very comprehensively, can it also be applied to plastic packaging bags? With the advancement of science and technology, the emergence of food laser marking machine is very It makes up for these shortcomings. It basically covers the entire application range of inkjet machines. Laser marking machines are no longer simply marking the product date and batch number, because of its unique visual and tactile effects and long-lasting non-erasable Features.

Anti-counterfeiting and anti-smuggling features of UV laser source marking machine

It has strong anti-counterfeiting and anti-smuggling characteristics. It is currently mainly used for online coding and marking on the surface of various products or outer packaging, as opposed to traditional laser marking, which can only mark stationary objects. The difference between the machine is: during the laser coding process, the products flow continuously on the production line, which greatly improves the efficiency of production and makes the marking machine adapt to the requirements of industrial production.

UV laser diode laser marking replaces inkjet marking

In traditional craftsmanship, ink jet coding is commonly used on food packaging bags to mark production date, batch number, and production location information. Such as common dairy products, bread, bottled beverages and other foods. However, the ink printing method is easy to be erased. Driven by profit, some illegal businesses erase the production date of the product that is about to expire, and then spray the new production date to continue selling on the market. This will have a great impact on people's health, and it will also seriously affect the balance of the market. However, the emergence of laser marking machines has replaced the inkjet marking.

The markings marked by laser marking technology can be seen everywhere

Through the technical processing of the laser marking machine, we can see the signs marked with laser marking technology everywhere when we buy goods in the supermarket. Similarly, the laser is also suitable for the needs of the gift packaging industry. The application of the laser marking machine is People's lives will become closer in the future.
