The printers are mainly concentrated in the beverage, beer, mineral water and other industries, but also began to develop in wire and cable, non-staple food, cigarettes, batteries and other industries. In addition to clearing its production date, the function of coding can also track potential problems and prevent counterfeiting. It can be said that the food industry is the largest market for inkjet printers.
At present, the printer has become an indispensable equipment in the production lines of various industries. The main difficulties to be solved in the packaging technology of the condiment packaging industry are:
First, it is suitable for severe production environment and strict hygiene requirements.
Condiment manufacturers must consider high dust and high humidity resistance when choosing a printer. Therefore, the stainless steel construction and grounding protection of the printer are often necessary.
Second, marking on the surface of various materials.
The packaging materials and marking contents of the condiments are various. It is necessary to identify different contents on the surface of different materials. For example, inkjet markings are required, and a series of nozzle models suitable for different requirements are required, including high marking quality. Small character sprinkler.
Third, the quality of printing, whether to obtain clear, high-quality logo, printing quality is a concern of production companies.
Adhesion of ink is often an important reference for ink selection.
1. High adhesion inks should be selected on high-gloss and high-density surfaces. In general, it is better to select general-purpose inks.
2. For the products to be packaged immediately after the coding, the drying time of the ink is particularly important. The quick-drying ink can be selected, and the blowing device can also be added to accelerate the drying of the ink.
3. For some cases where food is to be coded, food grade ink or environmentally friendly ink should be selected.
There are very few domestic manufacturers of inkjet printers. Only Beijing Huanuo and Zhihengda have several competitions. In the face of mature foreign companies such as the United States, Britain and France, the price is cheap. In today's globalized competition environment, domestic production is not so important. These big-name foreign companies have also set up factories in China. How to develop and how to innovate is the main problem at this stage.
