Laser Marking Machine for Food Packaging Film

For a long time, consumers like to look at the information on the packaging bag when purchasing food to judge whether the ingredients are fresh. Generally speaking, the marking information on these packages is an important and intuitive basis for consumers to judge whether food is safe or not, and can effectively inform consumers of the source of food, food materials, food expiration date, storage conditions and precautions, etc. information. However, at present, the news has reported that there are criminals in the market tampering with the production date of food and other information, causing hidden dangers for food safety. This issue deserves attention.

As an important part of commodities, food packaging protects food all the time. Whether the packaging material is safe or not and whether the information is correct or not is directly related to food safety. Obviously, there are many problems in the current packaging industry: some manufacturers blindly pursue novelty and good-looking, ignoring the quality of packaging materials; some personalized packaging design and production process is complicated and difficult to mass-produce; some bad manufacturers will directly produce The date and other information are altered, which seriously affects the reliability of the information. There are still many such problems, and the packaging design method urgently needs to be upgraded, so that consumers can buy with confidence.

Now in the process of product packaging information marking in the food industry, the main processing equipment is ink jet printer and laser printer. Obviously, the widely used ink jet printers can no longer keep up with the development of this industry: the marks of ink jet codes can be tampered with and erased, and are easy to be worn; ink jet printers often have ink clogging the nozzles, which requires maintenance personnel to carry out Maintenance; people's awareness of environmental protection continues to increase, and the requirements for ink safety and low pollution are getting higher and higher; it is difficult for inkjet printers 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 marking can make the surface material of the package evaporate, revealing the deep material, so as to engrave exquisite patterns, trademarks and words. Laser marking can use a laser with high energy density to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. The marking is clear, and it is environmentally friendly and pollution-free. The entire marking information is depicted on the packaging of the product, so it is difficult to tamper and counterfeit. On the whole, Juguangheng laser coding is better than the traditional inkjet coding method.
