Difficulties of coding technology in the food and beverage industry

Food is closely related to our daily life, and its particularity requires the importance of food coding and marking. The food industry is very different from other industries. Due to the differences in production environment and printing materials, it also poses a big problem for the coding technology industry, especially the beverage industry. The main difficulties in the current beverage industry coding technology There are the following points: 1. Print on different materials

to mark on the surface of various materials. The packaging materials of beverages are various, 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.

2. Inkjet printing quality

The inkjet printer is used 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 adopted, it is necessary to choose a laser machine that can adjust contrast, sharpness, height, etc., and obtain accurate and high-quality marking effects.

3. Fast bottling line speed

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, so Need to choose equipment and inks that can adapt to these high-speed production lines for high-speed coding. 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.

4. 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 to ensure good adhesion of the ink even if it is condensed again.

5. 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, and some must also Considering that the inkjet printer can be flushed with water along with the production equipment and the environment, the stainless steel structure and IP65 protection device of the inkjet printer is 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.

Some global professional inkjet printer manufacturers can provide certified inks that are printed on food packaging and comply with relevant laws and regulations (the logo is non-toxic to the food).

6. Bottleneck marking and recycling/non-recycling glass bottle marking

Some beverage manufacturers have been using inkjet printers to mark the production date, batch number, etc. on the bottle cap for many years. In some cases, This will conceal the trademark, or the printed content will be limited by the smaller area of u200bu200bthe bottle cap, and sometimes the code on the bottle cap will be scratched due to the stacking of the turnover boxes 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.
