Difficulties in coding technology in the food and beverage industry
  Food is closely related to our daily life, and its particularity requires the importance of food marking . The food industry is very different from other industries. The difference in production environment and printing materials has also caused a big problem for the coding technology industry, especially in the beverage industry. At present, the main difficulties in the coding technology of the beverage industry. There are the following points:
1 , printing on different materials
Labeling on a variety of different materials, beverage packaging materials, such as glass bottles, plastic bottles, laminated carton, cans, shrinkable plastic film are common packaging. To mark such a large number of materials, you need a printer manufacturer that offers a wide range of marking technologies. Because they can provide corresponding inkjet marking technology or laser marking technology solutions for different materials, and a wide variety of inks, it can guarantee high quality marking requirements on various materials.
2 , printing quality
Use the printer to mark the product's production date, batch number, etc., and obtain clear and high-quality logo. The quality of the print is clearly a concern of the manufacturer. The content requirements of the logo are complex and diverse, and numbers, texts, pictograms, logos, etc., are identified and matched to the packaging of the goods. If inkjet marking technology is used for marking, a range of nozzle models are required for different requirements, including small character nozzles that achieve extremely high marking quality.
If laser marking technology is used, it is necessary to select a laser machine that can perform various adjustments such as contrast, sharpness, and height to obtain accurate and high-quality marking effects.
3 , the bottling line speed
Beverage industry production capacity, especially some beer and beverage manufacturers with a number of high-speed filling lines, up to 36,000 bottles / hour speed, and therefore need to be able to choose to adapt to these high-speed production line equipment and high-speed ink Coding . If you choose a printer that can print up to 330 meters per minute , with a quick-drying ink that can be dried for up to one second, you can meet such high requirements.
4 , moisture and condensation
Moisture and varying temperatures condense on the material to be labeled, which is one of the most common and difficult problems in the beverage production industry. Pressurized sprinklers and stainless steel housings ensure maximum sealing; an adhesive film is provided to ensure good adhesion even if recondensed again.
5 , suitable for severe production environment and strict hygiene requirements
When choosing a printer, beverage manufacturers must consider strict hygienic conditions and shock absorption of the production line. Some also need to consider that the printer can be washed with water in production equipment and environment. Stainless steel construction of the printer And IP65 protection devices are often necessary. High humidity and high dust resistance make the printer work and work well even in harsh production environments. According to the characteristics of the food and beverage industry, it has decided its special requirements for the logo. Therefore, the provision of safe and reliable ink is also crucial.
Some of the world's leading professional printer manufacturers are able to provide inks that are printed on food packaging in compliance with relevant legal requirements ( identifying that the food is non-toxic ) and certified.
6 , bottleneck label and recycling / non-recycling glass bottle code
Some beverage manufacturers have used inkjet printers for many years to mark the date of manufacture, lot number, etc. on the cap. In some cases, this will mask the mark, or the print content will be limited by the smaller area of ​​the cap, and sometimes The code on the bottle cap will be rubbed off due to the stacking of the turnover boxes after stacking.
The solution is to code directly on the bottleneck. The cooling filling of the beverage production line always causes a layer of water to adhere to the surface of the bottle, and the glass bottle is coded under this environment and has good adhesion. Some glass bottles do not need to be recycled, and the ink on the bottle must have good adhesion. Some glass bottles need to be recycled. Once the empty bottles are recycled to the factory, the ink on the bottleneck must be cleaned. After years of unremitting efforts, a special quick-drying, scratch-resistant, water-resistant condensable alkali-washable ink has been developed and widely used in bottling plants. After empty bottles are recycled, they are cleaned by standard industrial alkaline water. Marks are completely washed away and can be marked again. This ink has been extremely successful in Coke bottling plants in many regions.
