We all know that the laser marking machine has been widely used in 3C electronic products. Can it also be applied to plastic packaging bags? With the progress of science and technology, the emergence of food laser marking machine has made up for these shortcomings. It basically covers the entire application range of inkjet machines. The laser marking machine is no longer simply marking the date and batch number of products. Because of its unique visual and tactile effects and long-term non erasable characteristics.

It has strong anti-counterfeiting and anti-counterfeiting characteristics. At present, it is mainly used for on-line marking on the surface of various products or outer packaging. Different from the traditional laser marking machine which can only mark stationary objects, the product flows continuously on the production line during the laser marking process, which greatly improves the production efficiency and makes the marking machine meet the requirements of industrial production.

In the traditional process, ink jet coding is generally used on food packaging bags to mark the production date, batch number and production place. Such as common dairy products, bread, bottled drinks and other food. However, the ink coding method is easy to be erased. Driven by interests, some illegal businesses will erase the production date of the products that are about to expire, and then spray the new production date to continue to sell in the market. This will have a great impact on people's health and seriously affect the balance of the market. However, the appearance of laser marking machine has well replaced the ink-jet marking.

Through the technical processing of the laser marking machine, we can see the marks marked with the laser marking technology everywhere when we buy goods in the supermarket. Similarly, the laser is also applicable to the needs of the gift packaging industry. The application of the laser marking machine will accompany people's life more closely in the future.
