What should you pay attention to when printing non-woven bags

The printing process of non-woven eco-friendly bags is mostly screen printing, which is commonly referred to as 'silk printing'.
But in the actual manufacturing process, customers often say: Why do some non-woven bags have good printing effects, and some have poor printing effects? Of course, this has a lot to do with the proficiency of the printing workers and printing technology, and, on the other hand, it has a lot to do with the selection of printing inks.
Generally, there are two kinds of printing inks for us to choose, one is water-based elastic glue and the other is ink. For example, the printing on general non-woven bags is made of water-based elastic glue. The biggest feature of this kind of water-based elastic glue is that the effect after printing has a significant concavity and convexity, and the coverage rate is good, and it is washable. And there is no peculiar smell at all, and the ink is generally used for screen printing of general objects, such as the appearance of a metal box, etc. The biggest feature of this printing process is its high printing accuracy. Why do we use water-based elastic glue for printing on our eco-friendly bags? This is mainly due to the following factors:
1. Different from the surface of ordinary objects, the mesh on the surface of the cloth is relatively large. Choose general ink printing. If the coverage is not good, that is to say, after printing, a lot of the background color of the cloth itself is exposed. This kind of printing effect will be difficult to see, so because of the surface properties of the fabric itself, we use water-based elastic glue.
2. Water-based elastic glue is a relatively environmentally friendly ink, and there is basically no peculiar smell. Therefore, since we are making non-woven bags, of course we must choose environmentally friendly inks.
Another situation is that some customers’ orders are exported to some European and American countries. Therefore, relatively speaking, there are higher requirements for the environmental protection of ink. Then, at this time, we need to be more cautious and avoid being in other countries. The time of import declaration cannot pass the environmental protection test. In this situation, we generally recommend that customers choose water-based elastic glue with high environmental protection function. This kind of water-based elastic glue with high environmental protection function not only has low content of heavy metals, but also has color fastness (the ability to adhere to the outer color of the cloth). ) And better washing resistance.
Of course, the manufacturing cost of a good water-based elastic glue is high, but for high-end customers, we still have to provide a better product quality. As a manufacturer with many years of manufacturing eco-friendly bags, no matter what kind of customer request, we use our professional nature to provide customers with the best service.
