For napkin paper products, they are in close contact with human body, such as mouth, hands or eyes, and food, which is hygienic and environmentally friendly
Very important. At present, the water-based ink used in tissue flexographic printing machine is environmentally friendly, pollution-free and odorless, which fully conforms to the requirements of hygiene and
Environmental requirements. In addition, when talking about colored napkins, many domestic consumers will invariably raise such a doubt,
That is, when using such colorful paper towels, whether the printing ink will pollute the skin or pollute the surrounding environment. actually
There is no need to worry about this. Tissue printers have fully taken these into account when selecting ink, especially the wear resistance of ink
Water resistance, water resistance and anti bleeding are all very important technical indicators. The ink used for tissue printing needs repeated skin contact.
Touch test, abrasion resistance and anti bleeding test, especially in home life, there may be many substances that are easy to induce ink bleeding. Therefore,
Compared with ordinary water-based ink, some ingredients are added to the formula of tissue printing ink, which can effectively prevent tissue
The printing ink on the surface of the printer will seep or dissolve when it contacts with water or strong alkaline substances.
The printability of tissue paper napkin printing ink is also very important. Its pH value, viscosity and other properties must be guaranteed during the printing process.
It is stable and suitable for drying, which meets the requirements of printing speed and post press processing. The printing speed of tissue flexographic printing machine can be up to 700m/min or 10000 sheets /min, the ink performance is very stable in the process of high-speed printing and high-speed folding.
Yes, improper viscosity of the ink may lead to fracture; Drying is too slow to meet the requirements of high-speed production; Drying too fast, then will cause dirty version.
