Laser marking eliminates food "date game"


  "Food safety" has always been a hot topic. Nowadays, people no longer only pay attention to packaging, taste, and price, but pay more attention to the safety of food, but what is less known is that food packaging on the market is mixed, and even the shelf life that people most believe can be faked. As an advanced laser processing equipment, the laser marking machine is applied to the food packaging industry, (Fiber Laser Marking Machine manufacturer china) which will help curb the "date game" on food packaging from the source.


An industry insider said: "Whether it is printing or inkjet printing, as long as the ink is used, it can be altered. The printing time information can be adjusted within three years." Regarding the issue of altering the shelf life of food, from large enterprises to Most small vendors know everything well. Only consumers are kept in the dark by "hidden rules", which seriously infringes on the rights and interests of consumers.

      Nowadays, most companies are already using laser marking, using laser to "engrave" information such as production date on packaging. Laser marking is a marking method that uses a high-energy density laser to locally irradiate the workpiece to vaporize the surface material or produce a chemical reaction of color change, thereby leaving a permanent mark. It has high marking accuracy, high speed, and Clear marking and other features.


   The laser marking machine can print a large amount of data in a very small range. The laser can mark the product material itself with a very thin beam.

Market competitiveness, environmental protection and safety, without any corrosiveness, completely isolated from chemical pollution, is also a kind of intimate protection for operators, ensuring the cleanliness of the production site, reducing subsequent investment, and reducing noise pollution.

In the future, as the current laser technology continues to mature, laser marking technology will be widely used in more and more fields.
