Diode-pumped UV laser marking of food packaging is difficult for tampering and counterfeiting

Laser marking is a marking method that uses a high-energy density laser to locally irradiate the workpiece to vaporize or change the color of the surface material, thereby leaving a permanent mark. Clear, environmentally friendly and pollution-free, the entire marking information is depicted on the product packaging, so it is difficult to tamper and counterfeit.

Due to the combination of Diode-pumped UV laser marking machine marking technology and computer, using the current computer software control system, it is not only possible to customize and mark various characters, product numbers, barcodes, serial numbers, two-dimensional codes, production dates, patterns, logos. and some special signs.

Therefore, the use of Diode-pumped UV laser marking in the food packaging industry has the following characteristics:

1. Not only can the overall brand influence be improved, but also the laser marking machine can effectively prevent the tampering of food packaging marking information and the circulation of counterfeit products and cross-regional sales and smuggling;

2. The laser-marked code, bar code, destination and other information can be used to establish a link database system, allowing us to track and query the latest product trends in time. The failure of industrial laser equipment during production will be relatively small,

3. It will greatly improve the efficiency and can operate continuously for a long time; it can also reduce production costs and reduce consumables, ensuring the environmental protection and safety of the entire processing process, and does not produce any harmful chemicals to the human body and the environment.
