Now the words green, low-carbon, etc. are closely related to our lives. Especially in first- and second-tier cities, people’s living standards change from day to day. Correspondingly, it has also caused a lot of pressure on our living environment. In our lives, the use of plastic bags is basically used every day in our daily lives. The high frequency of its use and the white pollution produced are undoubtedly a great pressure on the environment today.
The emergence of non-woven bags is to replace plastic bags and become green daily necessities. And because of the characteristics of non-woven bags, they are deeply loved by the people, thus driving the production of non-woven bags that demand more.
In the entire production process of non-woven bags, printing is the key in order to better reflect the theme on the bag. When printing non-woven bags, many merchants found that the printing effect of the patterns and other information of the finished product was not satisfactory. Can not achieve the desired effect. And the issue of printing ink is of great concern to the occurrence of this phenomenon. The dryness of the ink and the large color difference seriously affect the effect of the printed product.
In this regard, the people of Yongye Packaging reminded that in the printing process of non-woven bags, the choice of ink is important. The same ink should be used for the same batch of bags to avoid the problem of color difference. In addition, if two inks are used on the same product, and some ink properties are too different, there will be a phenomenon of non-fusion. In addition, in order to ensure that the properties of the ink remain unchanged, the storage environment of the ink is also important.
Avoid placing it in direct sunlight, and keep it in a dark room temperature indoor environment, so that it can be controlled within 10-26 ℃.
With the development of technology nowadays, the production equipment of non-woven bags is basically fully automated. The production speed is fast, so the printing speed is also fast. In order to achieve the printing quality of the bag, the drying speed of the ink should also be fast. If the drying speed of the ink is too slow, it will cause adhesion after the finished product comes out. Of course, if the ink dries slowly, you can also add a desiccant to increase its drying speed.
In the process of producing non-woven bags, in order to better reflect the products, when choosing inks, please use water-based inks for printing. In the entire bag printing industry, water-based inks have become the mainstream of the entire industry today.
