Recycling of premature foods and expired foods and then coding has become a big cancer in the food safety field, and the recycling of expired foods has become a black industry. Each product is clearly marked with important information such as product name, specifications, production date, expiration date, and production batch number, which is an important content of various product quality standards. In order to avoid or minimize the loss of food expiration, merchants will adopt some methods, one of which is food recycling. After that, distributors will often change the food production date by themselves, and change the date on the package as much as possible. It is understood that most of the production dates on food packaging are currently printed by ink jet coding equipment, but only mineral water, Red Bull, Wanglaoji and other fast-moving beverages that are not prone to inventory, and infant milk powder and other products with long shelf life, mostly use laser marking.标机。 Standard machine. Ink inkjet printers are relatively cheap, you can buy them for 20,000 to 30,000 yuan, while laser marking machines cost almost 100,000 yuan. In addition, inkjet printers contain diluents, and the production date printed on them can easily be incomplete. Fuzzy and easy to change. From a certain level, this kind of black interest is an improper choice for food distributors to weaken their social responsibilities and benefit the trend. It also reflects that related machinery such as coding equipment and printing equipment in my country's food packaging urgently need to be improved. In recent years, due to the continuous innovation of new technologies, laser inkjet printers and continuous automatic inkjet printers have also appeared one after another. Compared with traditional inkjet printers, they have achieved huge breakthroughs and improvements, solving high pollution, high consumables, and high Trouble, high maintenance issues. However, the widespread existence of inkjet printers and the persistence in production are still painful to the industry. At present, the industry is actively creating alternative equipment for ink jet printers, among which the laser marking machine is a very prominent one. Laser marking technology is a more advanced technology compared to ink jet coding technology. The application of laser marking machines in the Chinese market has just begun, but the development trend is rapid. It can vaporize the material on the surface of the food packaging in a very short time, and by controlling the effective displacement of the laser beam, it can accurately engrave exquisite patterns or text. Therefore, laser marking is the greenest and safest marking.标设备。 Standard equipment. The advantages of laser coding printing equipment are very obvious. Professionals said that it can reduce production costs, reduce consumables, and improve production efficiency; the anti-counterfeiting effect is obvious, and the laser marking technology can effectively inhibit product identification counterfeiting; it is conducive to product tracking and recording, and the laser marking machine can print Product batch number, production date, shifts, etc.; reliable equipment, laser marking (marking) machine with mature industrial design, stable and reliable performance, can work continuously for 24 hours, laser maintenance-free time up to more than 20,000 hours. In terms of performance, laser coding equipment does have obvious advantages in terms of safety, high efficiency, low pollution, and high retention. In this regard, some people will inevitably raise questions. Since laser coding can solve this type of problem, why ink printers still exist on a large scale. First, the price of laser coding equipment is more expensive, basically around 100,000, which is several times the price of inkjet printers; second, some distributors do not accept laser coding, and the food that uses laser coding is sold once it is about to expire. Failure to go out will bring losses to the dealer. However, industry insiders also pointed out that under the condition that food safety awareness is constantly increasing and illegal food operations such as tampering with production dates occur frequently, the disadvantages of inkjet printers will gradually be recognized, or they will withdraw from the market in the near future. , And was replaced by laser coding equipment. In the field of coding equipment manufacturing, in order to adapt to the development trend of the current society, intelligent and multifunctional continuous automatic coding technology has gradually matured and been applied. With the development of various industries, the demand for inkjet equipment is rising, and the development potential of inkjet printer market is worthy of recognition. In view of the current situation, the promotion of new equipment and new technology needs to be paid attention to. This is the common task of the food industry and the food machinery and equipment industry. Let laser coding equipment gradually replace ink coding equipment to ensure that food packaging is not hidden in the circulation, and effective promotion is one of the powerful measures. In addition, the coding equipment manufacturing industry should also spare no effort to continue to promote equipment innovation and achieve the development goal of high-energy and low-cost basic application equipment.
