UV laser prevents tampering with food production date and other information

For a long time, consumers like to look at the information on the packaging first when buying food to judge whether the food is fresh. Generally speaking, the labeling information on these packages is an important and intuitive basis for consumers to judge whether food is safe, and can effectively inform consumers about food sources, food materials, food expiration dates, storage conditions and precautions. But at present, the news has reported that criminals in the market have tampered with information such as the production date of food, which has caused hidden dangers to food safety. This issue deserves attention.

UV laser marking protects food

As an important part of commodities, food packaging protects food all the time. The safety of packaging materials and correct information are directly related to food safety. Obviously, there are many problems in the current packaging industry: some manufacturers blindly pursue novelty and good-looking, and ignore the quality of packaging materials; some personalized packaging design and production processes are complicated and difficult to mass produce; and some unscrupulous manufacturers directly produce The date and other information were altered, which seriously affected the reliability of the information. There are still many problems of this kind, and packaging design methods urgently need to be upgraded to allow consumers to buy with confidence.

UV lasers are widely used in food marking

Now in the process of marking product packaging information in the food industry, the main processing equipment is ink jet printers and laser printers. Obviously, the widely used ink jet printers cannot keep up with the development of this industry: the markings of ink jet codes can be tampered with and erased, and are easy to be worn; ink jet printers often block the nozzles and require professional maintenance personnel. Carry out maintenance; people's awareness of environmental protection is constantly increasing, and the requirements for ink safety and low pollution are getting higher and higher; inkjet printers are difficult to achieve high-efficiency one-item one-code marking for large-volume assembly line products. The emergence of laser coding has solved these problems and has been widely used in the industry.

Laser coding is better than traditional coding methods

Laser marking can evaporate the surface material of the package and expose the deep material, thereby engraving exquisite patterns, trademarks and text. Laser marking can use 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 is a marking method with high marking accuracy, high speed, and marking. Clear and other features, and environmental protection and pollution-free, the entire marking information is portrayed on the product packaging, so it is difficult to tamper and counterfeit. On the whole, laser coding is better than traditional coding methods.
