With the development of science and technology and people's awareness of health and environmental protection, high-pollution, high-consumption materials, "matrix ink coder" will gradually be eliminated, replaced by laser coding. Laser marking technology has unparalleled advantages in preventing modification and rapid identification.

Future laser printers will be widely used in the food industry

Due to the insurmountable problems of high pollution, high consumables, high failures, and high maintenance, the "matrix ink coder" can cause damage to the environment and operators, especially when it is used. Therefore, some developed countries have identified it as an alternative and eliminated equipment since the 1990s. Since this laser marking machine has certainly replaced the ink marking machine, and widely used in the food industry.

In 2014, CCTV's 3.15 party once again exposed the issue of food safety. Related companies repackaged expired food raw materials by tearing labels, changing packaging, altering the date of shipment with cleaning fluid, and using a knife to scrape. To the market.

In addition to the self-discipline of the enterprises, the relevant departments of the state ensure that the relevant departments of the state enforce the law to enforce the traceability of the food, pass the traceability mechanism, check the relevant intermediate links, and eliminate malicious tampering in the storage circulation to avoid similar occurrences. The 3-15 party revealed that such a thing happened. From a technical point of view, referring to traceability, we need to talk about coding technology. At present, the inkjet coding technology is mainly based on ink jet printing and laser jetting. However, in terms of preventing modification and rapid identification, laser jetting technology has obvious advantages. The progress of the future coding technology will inevitably provide a strong guarantee for the construction of food safety.
