There are many types of food packaging bags according to the industry, such as: ordinary food packaging bags, vacuum food packaging bags, inflatable food packaging bags, poached food packaging bags, retort food packaging bags and functional food packaging bags. Food packaging bags have so much effect, but do you know what you need to pay attention to when printing food packaging bags? Here are some tips for you to pay attention to when printing!
A: The food packaging bag should be properly adjusted for the pressure of the drum. When the packaging bag is printed, it will be slightly inadvertently rolled; if it is too heavy, the solid bottom is too big, it is easy to stick rubber or sticky roller. Therefore, the pressure of the drum should be reduced before printing, and the lining in the rubber should be reduced. In order to avoid sticking rubber and rolling rubber, add more additives or adhesives to the ink, and at the same time, be optimistic, avoid double sheets, multiple sheets and paper skew, and ensure that the pressure is not rolled on average.
Second: food packaging printing is the same as other printing products, the rules need to be correct, otherwise it will affect its quality. In the printing, the height of the front gauge and the height of the side gauge paperboard should be adjusted according to the thickness of the paper. At the same time, the pressure of the platen roller and the brush wheel on the paperboard should be adjusted, and the paper feeding cloth should be loosened. When the switch is found to be in a bad condition, it is necessary to check the paper feed situation and the pressure of the paper roller and the platen roller in time; for thick paper, the pressure of the platen roller and the brush roller should be heavier. And check the paper time and pull time, as well as the timing of the side gauge and the teeth, find the problem in time, until the up and down and left and right rules are correct and error-free.
Three: Ink color has a direct impact on the quality of printed products. Packaging plays an important role in protecting and decorating the goods. 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 the delicate and beautiful products, we need to really complete every step of the printing process, so that we can have considerable profit and quality.
