What challenges does the inkjet printer face in the food industry?

Food in daily life is closely related to us. Its particularity requires the importance of food coding and marking. Due to the differences in production environment and printing materials, it also poses a big problem for the coding machine industry. At present, the beverage industry The main difficulties of inkjet technology are as follows: different materials are printed on the surface of various materials for marking, and the packaging materials of beverages are varied, such as glass bottles, plastic bottles, laminated paper boxes, cans, and shrinkable plastics. Films, etc. are common packaging. To mark on so many material surfaces, a printer manufacturer that can provide a wide range of marking technologies is needed. Because for different materials, they can provide corresponding inkjet coding technology or laser coding technology solutions, coupled with a rich variety of inks, can ensure high-quality marking requirements on various materials. The printing quality uses the inkjet printer to mark the production date, batch number and other content of the product to obtain a clear and high-quality mark. Printing quality is obviously a concern for manufacturers. The content requirements of the logo are complex and diverse. Numbers, words, pictograms, logos, etc. must be identified and matched with the packaging of the goods. If inkjet coding technology is used for marking, a series of nozzle models suitable for different requirements are required, including small-character nozzles that can obtain extremely high marking quality. If laser marking technology is used, it is necessary to select a laser machine that can adjust contrast, sharpness, height, etc., and obtain accurate and high-quality marking effects. The bottling line speed is fast. The beverage industry has a large production volume, especially some beer and beverage manufacturers have multiple high-speed filling production lines, up to 36,000 bottles per hour. Therefore, it is necessary to choose a high-speed spraying line that can adapt to these high-speed production lines. Code equipment and ink. If you choose a printer that can print 330 meters per minute, with fast-drying ink that can dry up to one second, it can meet such high requirements. Humidity and condensation Humidity and changing temperatures condense on the materials that need to be marked. This is one of the most common and difficult problems encountered in the beverage production industry. The pressurized nozzle and the stainless steel casing can ensure the maximum degree of sealing; the accessory film is provided, even if it condenses again, it can ensure the ink with good adhesion. Suitable for severe production environment and strict sanitary requirements. When beverage manufacturers choose inkjet printers, they must consider strict sanitary conditions and the shock absorption of the production line. Some must also consider the inkjet printer's ability to interact with the production equipment and environment. Washing together with water, the stainless steel structure of the printer and the IP65 protection device are often necessary. The performance of resistance to high humidity and high dust enables the inkjet printer to maintain good operation and work even in harsh production environments. According to the characteristics of the food and beverage industry, the special requirements for marking are determined. Therefore, the provision of safe and reliable inks is also crucial. Ice cream packaging box inkjet printing Some global professional inkjet printer manufacturers can provide inks that comply with relevant laws and regulations and have passed certification for printing on food packaging. Some beverage manufacturers have been using inkjet printers for many years to mark the production date, batch number, etc. on the bottle cap. In some cases, this will cover up the trademark, or the print content is limited by the small area of u200bu200bthe bottle cap, sometimes even It may happen that the code on the bottle cap is scratched by stacking the turnover boxes on top of each other after bottling. The solution is to code directly on the bottleneck. The cooling and filling of the beverage production line makes the surface of the bottle always adhere to a layer of water. The glass bottle is coded in this environment and has good adhesion. Some glass bottles do not need to be recycled, and the ink marking on the bottle must have good adhesion. Some glass bottles need to be recycled. Once this empty bottle is recycled into the factory, the ink on the bottle neck must be cleaned. After years of unremitting efforts, a special quick-drying, scratch-resistant, anti-condensing alkali-washable ink has been developed and has been widely used in bottling plants. After the empty bottles are recycled, they are cleaned with standard industrial alkaline water. All the marks have been washed away and can be marked again. This ink has achieved great success in cola bottling plants in many regions.
