According to the scope of its application, food packaging bags can be divided into general food packaging bags, vacuum food packaging bags, puffed food packaging bags, boiled food packaging bags, steamed food packaging bags and functional food packaging bags. There are many applications for food packaging bags. What should you watch out for when printing food bags?

First, the food packaging bag printing to make appropriate adjustments to the roller pressure, the bag will be printed when accidentally rolling rubber; if it is too heavy ink, too much solid bottom is also easy to stick rubber or ink roller. Therefore, to reduce the pressure of the roller before printing, the lining inside the rubber is reduced. In order to avoid sticking rubber and rolling rubber, add more additives or auxiliaries to the ink. At the same time, be optimistic about avoiding double sheets, multiple sheets, and paper skew, and ensure that the pressure is not even when the rubber is rolled.

Second, the printing of food packaging bags, like other printed products, requires accurate rules, otherwise it will affect its quality. When printing, adjust the height of the front gauge and the height of the side pressure plate according to the thickness of the paper, adjust the pressure of the paper roller and the brush wheel on the paperboard, and tighten the paper feeding belt. When you turn on the machine, you find that the rules are not good. You must also check the condition of the paper feed, and the pressure of the passing roller and the pressure roller. For thicker paper, the pressure of the roller and the brush roller should be heavier. And detect the time of paper and pull rules, as well as the timing of the transfer between the side gauge and the tooth, find the problem and deal with it in time, until the top and bottom and left and right rules are accurate and error-free.

Third, ink color has a direct impact on the quality of printed products, packaging is an important role in the protection and decoration of goods, packaging and printing quality will directly affect people's aesthetics and consumption. Therefore, when printing packaging, it must meet the quality standards. To complete the exquisite and beautiful products, we need to earnestly complete every step of the printing process so as to have a considerable profit and quality.
