With the maturity of the concept of low-carbon life, more and more shopping malls choose environmentally friendly paper bags. To give customers a better impression. In addition to high-quality services and products, in fact, the beauty of customized paper bags cannot be ignored, and the probability of secondary use is greater, so they are sought after by many people. So, what do you need to pay attention to in the customization of paper bags?



1. The size of pigment particles and their degree of dispersion

Customized gloss for tote bags, depending on the ink film capillary. However, the apparent size of the pigment particles in the dispersed state is more important, which directly determines the state of the ink film capillary. Therefore, the pigment particles are small and dispersed well, which is very beneficial for paper bag printing.



2. The viscosity of the binder and the content of the pigment



The capillary network structure formed between ink pigment particles is an important aspect that determines the gloss of paper bag printing. At the moment of embossing, the ink is integrally pressed into the larger pores of the paper; after embossing, the binder begins to separate from the ink and penetrate into the smaller pores of the paper. Therefore, the size of the ink film capillary determines the amount of separation of the binder. The capillary retains the binder much more than the printing pressure presses the binder into the pores of the paper.



3. Drying time



The rapid drying of the ink film on the paper can reduce the amount of binder penetrated into the pores of the paper, thereby improving the gloss and smoothness of the ink film. The high gloss of the ink film means that the degree of specular reflection on the surface is relatively high, so that in most cases the human eye can see that the white light reflected on the surface is much less than that of the ink film with low gloss, which makes the color saturation more saturated. high. Therefore, the paper bag printing with high gloss looks more colorful and full.



4. Prevent the back from rubbing dirty



The customization of paper bags often has a full version, which is easy to cause the back to be dirty. The method of spraying powder is used to solve it. However, it should be noted that dusting will affect the surface gloss of the printed matter, pollute the environment, and wear and stick to the part of the offset printing machine, such as the delivery paper. What needs to be paid attention to is the correct arrangement of the printing color sequence. In order to avoid the back dirty caused by the collision of the paper when the imprint is not dry, the text and line version should be printed first, and then the solid version should be printed.



5. Post-press technology



After the paper bag is customized, it needs to be processed, so the appearance and quality will be stronger. There are a total of 12 post-press processes. They are bump embossing, die-cutting indentation, bronzing, partial UV process, freezing point snowflake, reverse frosting, embossing bronzing, photolithographic paper, laser transfer, glazing and waxing, hot stamping, lamination. The above are the issues that need to be paid attention to in paper bag printing. Of course, there are still many details that need constant attention in order to get a beautiful and practical paper bag.
