In fact, the process of effect printing paper began to produce in Tang and Song Dynasty, but the base and base at that time are changing slowly now. So the plant is so long since packaging printing technology, but it still seems a bit out of step in many aspects, and even eliminates the edge of the generation. Today's editors will share with you the problems faced by traditional printing technology, and customize handbags. 。
The most serious problem is environmental protection. In the past few years, more and more attention has been paid to environmental protection and emission standards are gradually shrinking, and the development of printing paper bag manufacturing space is gradually shrinking. To a large extent, the problem of ink materials, many chemicals and paint emissions are the most serious. Many small factories make bags at the end of this year, and choose secret treatment or closure because of him. The cost of making bags is too high and they don't want to be filtered, so they will lead to fines from environmental protection departments. These problems are real, and so far there is no good solution to this problem.
Many friends are confused, do not now develop technology to meet the environmental protection requirements of printed paper bags, in fact, no, as mentioned above, the launch filter is not handled properly, or the equipment is not good enough, so it can not meet, in order to meet this standard, paper bag customization manufacturers need a certain financial strength, the purchase of equipment, general equipment is not affordable, so it is not. Yes, wool comes from sheep. Big manufacturers are too expensive. Because the cost of all kinds of equipment comes slowly, and small workshops do not have these costs, so they are much cheaper. If they get these equipment, their cost will rise. They are not competing with big manufacturers in front of you.
Since there is no suitable machine for printing paper bag processing, it can choose some good environmental protection materials as raw materials, cost is cheaper than to buy thousands of machines. In theory, yes, but cheap green ink is not imaginary, and environmental protection ink is very expensive. On the contrary, at least more than 200% of the cost of color, so it can make many small workshops, without choosing to give them too much. So there are several reasons why environmental problems can be arranged in print all the time.
