In order to attract consumers, many companies have adopted color printing technology, this kind of packaging has been favored by consumers, thereby increasing their sight, and at the same time adding color to all kinds of food. Make packaging more and more versatile. It is very common to change the color of food packaging, but why does it happen?
1. The use and selection of printing inks
In ordinary packaging printing, water-based ink is replaced, and it is easy to replace water-based ink. On the other hand, oil-based inks are printed on the packaging of special packaged foods, and oil-based inks have good adsorption capacity and are difficult to replace.
2. Printing method
The usual packaging is a seal method, and the seal is printed on the surface of the package. Instead of lining printing for food packaging, lining printing is printed on the country side of the package, and by recombining and printing on the country side of the package, the printing is not exposed to the outside and the printing color can be protected.
3. Accumulate the environment
It is important to store the bag, put it on the bag and under the sword. In this environment, even if the printing method of the mark fades, the bag will fade, so please put the bag in the sun in a well-ventilated place and store it. This is the long-term preservation of the flashy color of the bag.
