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, boiled food packaging bags, retort food packaging bags and functional food packaging bags. Food packaging bags have so many functions, but do you know what to pay attention to when printing food packaging bags? The following will reveal some small details to pay attention to when printing! 1. The pressure of the roller should be adjusted appropriately for 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 will easily 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 agent should be added to the ink. Two: The printing of food packaging bags is the same as other printed products, and the rules need to be correct, otherwise the quality will be affected. 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 check the paper-feeding time and the pulling time, as well as the handover time between the side gauge and the swinging tooth, and find the problem and deal with it in time until the up and down and left and right rules are correct without errors. Three: 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 splendid products, we need to really complete every step of the printing process, so that there will be considerable profit and quality.
