Inkjet printer inks integrated into packaging materials are in urgent need of development

The incident of a dairy product tampering with the production date that broke out in 2012 is not just a public relations crisis in the dairy industry. It is important to restore customer trust, but the source, as a sign industry, should be reflected. This incident also gave a reminder to my country's inkjet printer manufacturers: Is it to develop non-erasable ink? Or is it to promote laser printers to a greater extent? Recently, some agents modify the production date of products from time to time. The reason why agents succeeded in tampering is not because of the inkjet printer, but because the ink solubility of the inkjet printer is easy to be used by criminals as a tool for making money. The most commonly used printing method on the market is inkjet printing. As far as European and American countries are concerned, most food products also use this coding method to mark the production date. Because the production date is only marked when the product is produced, the production date will not be added to the packaging label at the beginning of the design, and the inkjet printing has a great use in front of the production date with timeliness requirements. Because inkjet printing is simple and fast, and the price is cheap, merchants generally use this method to print the production date. Some media claim that the secondary sales phenomenon in the fast-moving consumer goods industry is a kind of unspoken rule, and this unspoken rule is well regarded as a business opportunity by some inkjet printing equipment sellers. On the Internet, you can see that many inkjet printing equipment sales slogans have added a modifiable production date, which almost acquiesces to this market demand. To change this phenomenon, relying on industry self-discipline is obviously not feasible, and must rely on regulations and production technology. Regardless of laws and regulations, as far as existing production technologies are concerned, laser printing and pinhole printing can also change the phenomenon of tampering. However, high prices and time-consuming factors are rarely adopted by merchants, and the development of new materials seems to be a difficult problem. Of course, it is more feasible to strengthen the development of new packaging materials, especially paper packaging. The paper fiber can melt into the ink and cannot be easily erased.
