Food safety issues have always been a hot spot for people, directly related to people's health. Sometimes, because there is no relevant information that can be used for tracing and identification, often we can only endless. This problem has also plagued food manufacturers. In order to effectively solve this problem and strengthen food supervision and control, more and more companies are gradually turning their attention to the current laser marking field.
In the past, most of the food markings were marked with traditional ink coding and pneumatic coding, which easily caused tampering and ambiguity of the marking information, which often made the traceability of food information not strong, and gave lucrative opportunity for some outlaws.Laser marking is different from traditional marking. It is a method of using a high-energy-density laser to locally illuminate a workpiece, causing a chemical reaction of vaporization or color change of the surface material, thereby leaving a permanent mark. The entire marking process is non-toxic. No pollution. At the same time, the marked patterns, characters and codes can be arbitrarily changed. The size of the characters can reach the order of millimeters to micrometers, which can meet the needs of a large number of information entry in the food industry, which is of great significance for the supervision of the food industry.
For the consumer, there is mark information that can be used for traceability and identification, and the relevant production company is found to defend the rights at the first time when the relevant counterfeit products are purchased. For enterprises, it can not only effectively prevent counterfeiting and smuggling of unscrupulous merchants, but also find the source of relevant food problems in the first time when there are related food problems. It can be said that in today's food industry, the emergence of laser marking machines is undoubtedly not to bring a protective armor to the current food industry, so that the food has a guarantee.
