[China Packaging Network] Recycled paper, waste paper recycling, environmental protection ink, by more and more attention of printing and packaging companies, packaging and printing industry has received a series of environmental laws and regulations on the impact. At the 12th National People's Congress convened in March this year, representatives of the National People's Congress have also proposed to levy an environmental tax, in this way to promote the process of environmental protection. Through various indications, environmental protection inks will surely have great development in the future.
Insiders pointed out that water-based ink is currently the world's most environmentally friendly ink, the solvent is water, non-toxic and odorless, can be naturally decomposed, and is now widely used in food packaging, pharmaceutical packaging, cigarette packets and other industries.

Foreign companies generally require the use of water-based ink, while reducing the printing area on the package, mostly based on simple patterns.
Domestic companies usually emphasize the realism of the design on the packaging. This will increase the use of ink, and even in order to achieve the color effect of the customer's requirements, it is necessary to repeatedly print several layers of ink on the packaging. Although ink printing is used, this "wasting of resources" behavior cannot be fundamentally called "environmental protection."
In developed countries such as Europe, America and Japan, aqueous inks have gradually replaced solvent inks and become special inks for printing methods other than offset printing. In the United States, 95% of flexographic prints and 80% of gravure prints use aqueous ink. This market structure benefits mainly from the simplistic concept of life in foreign countries. They can accept that the printing of packaging is not so beautiful, the pattern is very simple, and even only a few letters. Foreign people can realize that the simpler the printing on the packaging, the less the amount of ink, the less impact on the contents, and the safer and more environmentally friendly.
Our consumers are still in the first stage of visual effects, because consumers like to attract the eye of the bright colors, food companies will vote for it. Therefore, to change this situation, it is first to change the aesthetic concept of consumers.
Cheap domestic waterborne ink dominates the market
According to reports, the main application fields of water-based inks are flexible printing and gravure printing. In recent years, the development speed in the country is relatively fast, but there is still a large gap between the application volume and foreign countries. The water-based inks that are widely used in foreign countries have excellent performance in addition to their environmental protection. They have stable ink, high brightness, strong coloring power, no corrosion of plates, strong adhesion after printing, adjustable drying speed, and strong water resistance. Four-color overprint and spot color printing can be used and other features. The development and application of water-based ink in our country started late, but it has developed rapidly, especially in recent years. With the increase in demand for water-based inks, the quality of domestic water-based inks has also been improved. Traditionally, water-based inks have been drying up, have poor gloss, are not water-resistant, and are not printed correctly, and have now been significantly improved. In the case that the price of imported water-based inks is generally high, cheap domestic water-based inks have gradually occupied the market.
How can a printing company pay attention to cost efficiency and green environmental protection?
On the one hand, the government, the media, etc. should assume the responsibility of correctly guiding consumers and let consumers know what kind of packaging is environmentally friendly. For example, to change the aesthetics of consumers, instead of focusing on the color of the packaging and the gorgeousness of the colors, we should appreciate the creativity on the packaging. As a result, companies will change their packaging in order to cater to consumers' tastes, so as to reduce the use of ink and promote the widespread use of environmentally friendly ink. In addition, considering the deinking step after product recovery, if the ink stick is too heavy, the amount of deinking agent that is bound to be required will also increase. This will cause great pollution to the environment, thus reducing the printing area. It is necessary to reduce the amount of ink used.
On the other hand, printing companies must actively assume social responsibility. Take synergy packaging as an example, the principle of "two prices" has always existed in the operation and management of enterprises. Compared to customers who require the use of solvent-based inks, customers who use water-based inks in large quantities can get more benefits. If you choose monochrome printing, the cost is even lower. In addition, Heyi Packaging has always been advocating with customers to reduce the printing area. We must aim at simple designs and designs and try our best to achieve environmental protection.
