With the deepening of the concept of environmental protection and low carbon, health issues have become more and more important, and green color boxes have become a trend. Green color boxes, inks are the first to bear the brunt. Many people have begun to pay attention to the toxic incidents of Color box printing inks. In the printing industry, in order to allay consumers’ concerns, color box printing pays attention to non-toxicity and moves towards green printing, so use flexographic printing. Many companies have adopted water-based inks, which are basically non-toxic. A major problem of ink toxicity lies in organic solvents, which mainly refer to toluene, xylene, polycyclic aromatic hydrocarbons and their derivatives. They will volatilize into the air along with the drying of the ink, which not only pollutes the air, but also poses a threat to the health of printing operators. There is also a volatile organic compound (VOC), which has many types, such as alcohols, esters, ethers, ketones, and mineral oils. Like aromatic hydrocarbon solvents, it will volatilize as the ink dries, thereby polluting the air. Another big problem of ink toxicity lies in pigments, such as heavy metals in inks. Although most inks have reduced the content of heavy metals, some people use chrome yellow and chrome red to make inks.
To solve the toxicity problem of color box inks, from a narrow perspective, it is necessary to use green environmentally friendly inks. First, the ink composition should be changed, that is, the new ink should be formulated with environmentally friendly materials. There are mainly water-based inks, UV inks, water-based UV inks and some alcohol-soluble inks. Try to buy some authentic products, pay attention to your lifestyle, and don't let any ink touch your mouth. Driven by the policy, the greening of color boxes will be accelerated.
