Food packaging bags can be divided into: ordinary food packaging bags, vacuum food packaging bags, puffed food packaging bags, boiled food packaging bags, retort food packaging bags and functional food packaging bags according to their scope of application. There are many applications of food packaging bags, so what should we pay attention to when printing food packaging bags?

1. The pressure of the roller should be adjusted properly in the printing of food packaging bags. If the packaging bag is printed accidentally, the rubber will be rolled; if the ink color is too heavy and the solid bottom is too large, it is easy to stick to the rubber or ink roller. Therefore, the pressure of the cylinder should be reduced before printing, and the lining in the rubber should be reduced. In order to avoid sticking rubber and rolling rubber, more additives or rutting adhesives should be added to the ink, and at the same time, it is optimistic to avoid double sheets, multiple sheets and paper skew, and ensure that the pressure is even and the rubber is not rolled.

2. The printing of food packaging bags, like other printed products, needs to be accurate, otherwise it will affect its quality. During printing, the height of the front gauge and the height of the side gauge pressboard should be adjusted according to the thickness of the paper. At the same time, the pressure of the pressing roller and the brush roller on the feeding cardboard should be adjusted, and the loose belt should be tightened. If you find that the rules are not good when you start the machine, you should also check the paper feeding situation in time, as well as the pressure of the paper roller and the paper roller; for thicker paper, the pressure of the paper roller and the brush roller should be heavier. And detect the paper-feeding time and the pulling time, as well as the handover time between the side gauge and the swinging tooth, and solve the problem in time until the up and down and left and right rules are accurate and error-free.

3. Ink color has a direct impact on the quality of printed products, and packaging plays an important role in protecting and decorating items. The quality of packaging and printing will directly affect people's aesthetics and consumption. Therefore, when printing packaging, it must meet the quality standards. To complete exquisite and beautiful products, we need to complete every step of printing carefully, so as to have considerable profit and quality.
