Walking into the supermarket, all kinds of food on the shelves are colorful and dazzling. In terms of how to buy food, I believe everyone has their own unique standards and opinions. But if we observe carefully, we will find that more and more people will habitually check the production date, best use date and other identification information on the packaging when buying food, especially for some products with a short shelf life. food. It seems that the date marking on food packaging is already a key element that people must pay attention to.
The identification information on food packaging can be divided into two categories according to the printing method: one is the direct contact method, such as coding, embossing, printing, etc. The characteristic is that the equipment is in direct contact with the object, and the object needs to bear Certain pressure cannot be used for objects such as eggs and cakes that cannot withstand pressure and have irregular shapes; the second is indirect contact, which is mainly reflected in the coding technology, which is characterized by the fact that the device does not need to touch the object, but will The information is printed on the surface of the object, which avoids the risk of damage to the content due to pressure, and can also adapt to the printing needs of various shapes of objects. At the same time, the coding technology has high-speed characteristics, which is very suitable for the needs of modern high-speed production in the food industry.
For the application of coding technology in the food industry, as well as the diversity of food packaging, Beijing Saiteng provides two solutions.
Scheme 1: Saiteng launched the Microdot series of small-character inkjet printers to produce the production date, batch number and other marks on food packaging. This machine is in the leading position in technology among similar domestic products and passed the first CE certification. The Microdot series machine adopts a fully enclosed casing design, no heat dissipation holes, and low power consumption, which can adapt to humid, hot, and dusty production environments. In addition, in order to cooperate with the high-speed operation of the product production line, the maximum speed of Microdot can reach 95 meters per minute in two rows, which fully meets the needs of high-speed production lines. In order to ensure the continuity of food production and minimize the production interruption caused by ink replacement, Microdot does not need to stop the machine, and ink bottles can be replaced instantly, which is quick and clean.
Scheme 2: In order to facilitate storage and circulation, most food products are packed in cartons, so making identification information on the surface of the carton packaging is also a problem that inkjet printer manufacturers need to solve. Beijing Saiteng introduced the American Matthews large-character inkjet printer, which uses advanced solenoid valve technology to print various texts and patterns on the surface of the outer box. In the process of product circulation, the DOD large-character inkjet printer is used to print different area codes on the outsourcing to prevent the phenomenon of fleeing goods, which is effective and easy to use. In addition, with the large-character invisible anti-counterfeiting ink, the anti-counterfeiting function of the product can also be realized. Aiming at the phenomenon that some large outer packaging boxes are not suitable for assembly line, Beijing Saiteng developed a small hand-held inkjet printer on the basis of large-size printers. The whole machine is placed on a supporting trolley, and only needs to be pushed. The trolley can be motorized and not moved, and it is very convenient to use.
In recent years, people have paid more and more attention to food hygiene, and the government has also issued some corresponding laws and regulations to regulate the food market. With the improvement of people's awareness of environmental protection and health, not only the food itself, but also food packaging has become the focus of attention. Inkjet printers generally use ordinary ketone-based inks. This kind of ink will produce gas harmful to the human body when it evaporates, which is unhealthy. If it is printed on the surface of food, it may directly penetrate into the interior and cause pollution. In comparison, the use of alcohol-based inks can avoid this phenomenon. The volatile substance of alcohol-based ink is ethanol (that is, alcohol), which is non-toxic to the human body. At present, the 100% alcohol-based ink developed by Beijing Saiteng has been put into the market, and all parties have responded well. Based on this, it can be seen that such inks should have broad prospects in the food production industry in the future.
In addition, the coding industry is also facing problems such as how to improve product stability and reduce product costs. Because inkjet printers are high-maintenance products, improving stability is a serious issue facing manufacturers, which needs to be solved through continuous technical research. At this stage, in order to ensure the interests of customers, each inkjet printer manufacturer has strengthened the after-sales service, established a professional after-sales engineer team, and carried out regular return visits and repairs to the products. Once the machine fails, it is guaranteed to arrive in the shortest time. Repair, reduce customer losses to a minimum.
