What details should be paid attention to in the custom printing of food packaging bags?

Spout bag is also called spout bag English name: spout bag.
The nozzle bag is a new beverage and jelly packaging bag developed on the basis of the stand-up bag.
The structure of the nozzle bag is mainly divided into two parts: the nozzle and the stand-up bag. The structure of the stand-up pouch is the same as that of the ordinary four-sealed stand-up pouch, but composite materials are generally used to meet the requirements of different food packaging. The suction nozzle part can be regarded as a general bottle mouth with a suction tube. The two parts are closely combined to form a beverage package that supports smoking, and because it is a flexible package, there is no difficulty in sucking, and the contents are not easy to shake after sealing, which is a very ideal new beverage packaging.
The biggest advantage of spout bags over common packaging forms is portability. The mouthpiece bag can be easily put into a backpack or even a pocket, and it can be reduced in size as the contents are reduced, making it more convenient to carry. At present, the soft drink packaging on the market is mainly in the form of PET bottles, composite aluminum paper bags, and cans. Today, with the increasingly obvious homogenization competition, the improvement of packaging is undoubtedly one of the powerful means of differentiated competition. The nozzle bag combines the repeated packaging of PET bottles and the fashion of composite aluminum paper bags. At the same time, it also has the incomparable advantages of traditional beverage packaging in terms of printing performance. Due to the basic shape of the stand-up bag, the display area of ​​the nozzle bag is obvious. Larger than a PET bottle, and better than a package such as a Tetra Pillow that cannot stand. Of course, because the nozzle bag belongs to the category of flexible packaging, it is not suitable for the packaging of carbonated beverages at present, but it has unique advantages in fruit juice, dairy products, health drinks, jelly food and so on.
When the food packaging bag is turned on, it is found that the rules are not good, and it is necessary to check the paper feeding situation and the pressure of the paper roller and the pressing roller in aluminum foil for pet food packing time; for thicker paper, the pressure of the pressing roller and the brush roller should be heavier. And test the time of unloading the paper and the time of pulling the gauge, as well as the food packaging bags with side gauges and teeth, according to their application scope, they 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. 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.
2. The printing of food packaging bags is the same as other handover times. Problems are found and dealt with in time until there is no error in the up and down and left and right rules.
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 the printing carefully, so as to have considerable profit and quality.
