In recent years, "food safety" has been a hot topic. Nowadays, people no longer only pay attention to packaging, taste, and price. Instead, they pay more attention to the safety of food. However, it is little known that the food packaging on the market is a mixed bag. Even the most people believe that the shelf life can be falsified. As an advanced laser processing equipment, Laser Marking Machine used in the food packaging industry will help contain the “date game” on food packaging from the source.
An industry source said: "Either printing or coding, as long as the use of ink can be altered. Printing time information, within three years can be arbitrarily adjusted."
Regarding the problem of altering the shelf life of foods, most of them, from large companies to small traders, are well aware of this. Only consumers are kept in the dark by "hidden rules." Unscrupulous companies played "date games" and illegally profited. They dealt with foods that had already expired or were about to expire, put them on the market after being replaced, and seriously infringed upon the rights and interests of consumers.
So how to stop the "date game" on the food packaging from the source?
The most effective measure is to use laser marking to laserize the production date and other information on the packaging. Laser marking is a marking method that utilizes high-energy-density lasers to locally irradiate workpieces to vaporize or color change the surface layer materials, leaving a permanent mark. It has high marking accuracy and high speed. Clear features and other features.
However, many food-unit manufacturers are far from it. The main reason is that it is too expensive and the equipment price is about twice that of using ink equipment. Actually not. In the early days, the price of Laser Marking Equipment may indeed be higher than that of ink equipment. However, in the long run, laser marking machines can reduce production costs, reduce consumables, increase production efficiency, and be environmentally friendly and safe without any harm to the human body and the environment. Chemical material. Then the ink jet printer still needs to continue to bear the cost of purchasing ink.
The laser marking machine can print a large amount of data in a very small range. The laser energy can be marked on the product material itself with a very fine beam. The printing accuracy is high, the control is accurate, and the printing content is clearly and perfectly interpreted. It is extremely strong. Market competitiveness, environmental protection and safety, no corrosiveness, complete isolation of chemical pollution, and an intimate protection for operators, ensuring clean and tidy production sites, reducing late investment, and reducing noise pollution.
