Food packaging bag is essential in our life, it can not only play a good role in protecting the product, but also can better convey the product information to consumers through exquisite packaging, and can also play a good promotion effect. In the shopping malls, food in the production process needs to go through a lot of procedures, and the final process is packaging, so packaging plays a very important role in food. But do you know these small details must be paid attention to when printing food packaging bags?
1： The roller pressure should be adjusted properly for food packaging bag printing. If the ink color is too heavy and the solid bottom is too large, it is easy to stick rubber or ink roller. Therefore, before printing to reduce the pressure of the drum, rubber lining to reduce. In order to avoid sticking rubber, rolling rubber, to the ink to add some additives or track adhesive, at the same time, to avoid double sheet, multi sheet and paper skew, to ensure that the pressure is uniform, do not roll rubber.
2： Food packaging bag printing, like other prints, needs to be accurate, otherwise it will affect its quality. When printing, it is necessary to adjust the height of the front gauge and side gauge pressboard according to the paper thickness, and at the same time, adjust the pressure of the paper pressing wheel and brush wheel on the paper conveying board, and tighten the loose paper feeding cloth belt. When starting the machine, if you find that the rules are not good, you should check the paper feeding situation and the pressure of the paper wheel and the pressure wheel in time; for thicker paper, the pressure of the paper pressing wheel and the brush wheel should be heavier. And the paper time and pull gauge time, as well as the side gauge and swing teeth hand over time, found problems in time to deal with, until up and down and left and right rules are accurate without error.
3： Ink color has a direct impact on the quality of printed products, while packaging plays an important role in protecting and decorating articles.

Bag material knowledge: mLLDPE resin
With the continuous development and change of packaging market, there are more and more special requirements for packaging. The metallocene polyethylene (mLLDPE) was polymerized by Dow Chemical Company in USA by metallocene catalysis. Such as apfinity, pop1880, 1881, 1840, 1450 and other resins. Then Exxon in the United States. Mitsui of Japan and Philips of the United States also successively produced mLLDPE. For example, Exxon's ex-ceed350d60, 350d65, Mitsui Petrochemical's e-volume sp0540, sp2520, Philips mpact d143, d139, etc. MLLDPE can be mixed with LDPE and LLDPE, and the mixing ratio can be from 20% to 70%. This kind of film has good tensile strength, impact strength, good transparency, good low temperature heat sealing and anti pollution properties. The composite materials with its inner layer are widely used in frozen and refrigerated food, shampoo, oil, vinegar, soy sauce, detergent, etc. It can solve the packaging speed, broken package, missing package and penetration of the above-mentioned products in the process of packaging production and transportation.
