Eco-friendlyInkfactoryManufacturs Due to the harm of benzene soluble plastic gravure ink in environmental protection and occupational health, as well as the hidden dangers to the health and safety performance of products, it is necessary to actively develop and apply green gravure ink that meets the requirements of environmental protection. There are two kinds of new environmental protection inks: benzene free ink and water-based ink. After 2000, some domestic ink manufacturers with strong technical strength successively launched new environmental protection inks.
With the introduction of a series of non aromatic solvent inks (such as alcohol and ester soluble inks), water-based inks, UV inks, soybean oil-based inks and other environmental friendly inks, the environmental protection of inks is gradually deepening.
Environmental friendly and non-toxic ink -- four steps of environmental protection
Environmental protection is only relative, but for the offset printing ink with the largest use, its contribution to environmental protection has not stopped.
The first generation of environmental protection products -- heavy metals up to standard
This has been achieved many years ago. Of course, it can not be completely ruled out that a few low-cost and low-grade offset printing inks still contain a large amount of heavy metals. Through printing, heavy metals will remain in the printed matter. The content of heavy metals in dry ink film is more than that in wet ink. Of course, if you do not directly contact with food, it may be harmless not to enter the human body, but in fact, it is difficult to avoid. Therefore, the standard of heavy metals in ordinary offset printing ink is the first step to realize ink environmental protection.
The second generation of environmental protection products -- no aromatic hydrocarbons
The main solvent in common traditional offset printing ink is mineral oil. Some mineral oils contain high content of aromatic hydrocarbon solvents, which are easy to emit pungent smell. Although aromatic hydrocarbons have almost no residue on completely dry prints, the market still looks forward to relevant environmental protection products. Therefore, in some high-grade inks, mineral oils that do not contain aromatic hydrocarbons have been basically replaced.
The third generation of environmental protection products - soybean oil-based ink, the aromatic hydrocarbons of mineral oil in the ink are reduced or disappeared, which still can not avoid the influence of VOC. Therefore, soybean oil-based ink in which some mineral oil is replaced by soybean oil appears. Due to the relative reduction of VOC, the air pollution in the printing workshop will also be reduced, but after all, there is still a small amount of mineral oil.
The fourth generation of environmental protection products - low VOC ink (VOC < 1%), which contributes more to environmental protection than water-based ink and UV ink. Discarded printed matter can be recycled. Even if it is really discarded, it is easier to decompose in nature than other inks. Therefore, it can be regarded as the most environmentally friendly ink.Eco-friendlyInkfactoryManufacturs
