Life Cycle Analysis Of Soy Ink

Published on Jan. 08, 2020

In recent years, with the improvement of living standards, people have not only increased the internal quality requirements of goods, but also have beautiful and generous outer packaging. Therefore, packaging printing has become one of the indispensable important links in the field of commodity circulation and sales, and its economic value is obvious to all. At the same time, the negative impact of packaging on the environment cannot be ignored. Among them, the pollution of the ink to the environment has become the focus of attention. In recent years, a soy ink known as green ink has appeared in the public eye, but can it bring real environmental protection to the printing industry?

Life Cycle Analysis Of Soy Ink

Soy Oil Based Offset Printing Ink

Soy based offset ink manufacturer compares ordinary inks with environmentally friendly soybean inks, analyzes the environmental protection of soybean inks from three aspects: soil, air and water, and looks at the entire life cycle of soybean ink products , To find a more environmentally friendly design idea for the printing industry.

The so-called soy based offset ink is an environmentally friendly ink that replaces some petroleum mineral oil in the ink with soy oil. The other ingredients are roughly the same as those of ordinary inks. They are also divided into pigments, binders and mineral oil , Additives and so on. In the ink raw materials, the use of soy ink greatly reduces the heavy metal pollution caused by the extraction of petroleum. The VOC content in the ink (which can cause harmful volatile organic compounds, such as toluene, xylene and ethylbenzene) is also reduced 30% ~ 60% reduced to 5% ~ 15%.

Although soy oil based offset printing ink has higher raw material costs, it spends less on various expenses such as pigment use, volatile organic compounds use, and printer cleaning costs. Soy ink is resistant to friction, readers will not stain their hands with black when reading newspapers, and there is no irritating odor, and petroleum-based inks are easy to contaminate readers' hands due to poor friction resistance. Soy ink has a wide range of colors, and the same amount has better effect than ordinary ink; and when recycling waste printed materials, soy ink is easier to deink than ordinary ink, and has less damage to paper, which is beneficial for recycling and waste residue after deinking It also degrades better and is a relatively more environmentally friendly ink.

However, as an environmentally friendly ink, soybean ink does not really achieve green and pollution-free printing. The whole process of soybean ink from production to recycling still caused different degrees of environmental impact.

Overall, soy ink is a relatively healthier and more environmentally friendly alternative to ordinary inks, but soy inks still cause environmental pollution. There is currently no truly “green” ink in the world, but from the perspective of global sustainable development, the more renewable content the product incorporates in the production process, the better, because at least we are moving towards the right Move forward.
