Recently, Yiwu Tongxiang Yonggu Adhesive Co., Ltd. spent 300,000 yuan to Zhejiang Weihang New Material Technology Co., Ltd. to buy more than 10 tons of WH-S water-based plastic ink for food packaging printing. This new water-based ink is developed by the "Water-based ink Research and Development Center" jointly established by Weihang Company and Beijing Institute of Printing. With its green characteristics, it has become the best product to replace benzene-soluble ink.

With the increasing green safety standards in food packaging, printing and dyeing industries, since 2009, "Weihang" began to develop new environmentally friendly printing and dyeing materials. "At present, most of the packaging printing inks on the market add toluene, ethylene and other organic chemical solvents, which are flammable, explosive, volatile, and contain toxicity and other hazards. This traditional ink is unstable in terms of safety, and cannot meet the printing quality requirements without adding organic solvents." "Weihang" chairman He Xianwei considered that the new ink to achieve non-toxic, non-irritating odor, non-corrosive and other standards, it is necessary to overcome the compatibility of organic solvents and ink, such as using "water" to replace organic solvents, may be the best solution.

In 2010, "Weihang" and Beijing Institute of Printing jointly established the "Water-based ink Research and Development Center", invested nearly 30 million yuan, through more professional equipment and technology, successfully developed "WH-S water-based plastic ink" last year, filling the gap in domestic "green and safe" film printing materials. "Weihang" has also become the national ink manufacturers Green Alliance water-based ink research and development center and production base.

After developing the "WH-S type water-based ink", "Weihang" began to further study the patented products of the printing and dyeing industry, developed 2 invention patents and 4 practical patents, and successively developed the "WH-ZX186 paper water-based ink", "WH-YC808 water-based ink for hydropine paper" and other provincial high-tech products, all of which meet environmental protection standards.

"The raw material price of no added pigment is 20 to 24 yuan /kg, and our water-based ink is 35 yuan /kg, counting the manufacturing cost, traditional organic ink has no price advantage." "And we have no competitors in the industry, so we don't have to worry about sales," He said confidently.

In the first three quarters of this year, the sales of "Weihang" water-based ink were two times higher than the whole year of last year, and have exceeded 6 million yuan. At present, the sales scope of new products continues to expand, customers from Jiangsu, Anhui and other provinces have taken the initiative to visit and sign contracts, customers from Thailand and Malaysia are also pouring in, and product sales are growing exponentially.

"The report of the 19th National Congress pointed out that we must adhere to the new concept of development. Development must be scientific, and the concept of innovative, coordinated, green, open and shared development must be firmly implemented." He Xianwei said that the ink industry is in a period of rapid change, according to the national elimination and rectification of "low small scattered" and other industrial policies, it is expected that in the next five years, the national ink production will increase from the current 600,000 tons to 800,000 tons, and the number of ink enterprises will be reduced from the current nearly 1,000 to less than 300. The strong industry "Xian" will provide new development opportunities for "Wei Hang". "Environmental protection and low-carbon industries are supported by national policies. We will continue to adhere to the concept of environmental protection and innovation, and play our own green brand." He Xianwei said.
