Application of Laser Marking Machine for Food Packaging

With the development of the laser industry and the improvement of laser technology, laser marking technology has been applied to all walks of life. Because the use of laser marking machine has no consumables, no pollution to the environment, high efficiency, beautiful effect and other characteristics, it gradually replaces many traditional marking processes.

Marking on food packaging is one of the common applications of laser marking machines in our daily life. By printing the date and other information on the outer packaging of food, we can accurately understand the product’s expiration date, origin, as well as the ingredients contained in the product, storage conditions and other information. In the past few years, these processes are usually completed by inkjet printers. However, inkjet printing has many disadvantages, for example, the information is easily tampered with, and it cannot play a good role in marking.

Now most products are marked with laser marking machines. Laser marking is to locally irradiate the workpiece by a laser with a high energy density, so that the surface material vaporizes or undergoes a chemical reaction of color change, thereby leaving a permanent mark. Once the mark is finished, it can no longer be changed and erased, which can play a better role in protecting the quality of the product.
