Polyurethane inks passed through the identification

Recently, the polyurethane ink connecting material developed by Xinhui Chemical Products Co., Ltd. of Zhongshan City, Guangdong Province has passed the provincial scientific and technological achievements appraisal. This is the first company successfully developed in China and has contributed to the rapid development of China's printing and packaging industry.
In recent years, with the rapid development of China's printing and packaging industry, the demand for printing inks has continuously increased. So far, the amount of gravure printing inks used in plastic printing and packaging in China has exceeded 50,000 tons/year, and domestic use in plastic printing and packaging today Most of the gravure printing inks are polyamides containing benzene solvents, and chlorinated polypropylene system inks. Since benzene solvents are toxic substances, inks containing benzene solvents release toxic substances in the process of manufacture and use to pollute the air and endanger people's health. They have been banned from use in Europe, the United States and other countries and regions. Instead, they are used instead. Green type ink product. In addition, due to its excellent tensile strength, temperature resistance, gas barrier properties, and low hygroscopicity, polyester films are widely used in plastic composite packaging. The demand for polyester films in China is 15% per year. With increasing speed, it is well known that chlorinated polypropylene inks are difficult to meet the printing requirements for polyester films. Therefore, the widely used in printing and packaging in advanced advanced Western countries is a wide range of applications, strong adaptability, and compliance with environmental protection and food hygiene requirements. Polyurethane, alcohol-soluble inks. With China's accession to the WTO, many domestic printers and packaging manufacturers have developed new packaging and printing products that comply with policies and regulations, environmental protection, industrial hygiene, and resource policies and regulations in order to enter products into the international market and meet international standards. The use of polyurethanes and alcohol-soluble inks that meet the requirements of environmental protection and food hygiene in the printing and packaging of foods and pharmaceuticals continues to increase, and the market prospects are vast. However, the current inks for the production of polyurethane inks and alcohol-soluble inks mainly depend on imports. Imported polyurethanes and alcohol-soluble inks are expensive, and the country needs to spend a large amount of foreign exchange to purchase them; the production cost is high; and the imported alcohol-soluble ink connecting materials Most of them are nitrocelluloses, which are extremely inconvenient to use and produce. Their adaptability is relatively narrow, and their performance is not ideal. It is one of the major factors that make it difficult to popularize polyurethane and alcohol-soluble inks in China.
The XH-IBPU series polyurethane and alcohol-soluble ink connecting materials developed by Xinhui Company according to foreign advanced technical standards are especially suitable for the printing and packaging of foods and pharmaceuticals. They are widely used in the plastic flexible packaging of PET, NY, BOPP, and PE. High and low speed printing of materials. Its printing products have very good adhesion, and have good gloss and transparency, and have wider printing applicability than the inks produced by the chlorinated polypropylene inks used in the current market, and have superior performance and affordable price. Compared with imported products, inks produced with XH-IBPU series polyurethane and alcohol-soluble ink connecting materials have considerable market competitive advantages compared with imported similar products, and are ideal connecting materials for replacing and eliminating chlorinated polypropylene inks. With the development and application of polyurethane and alcohol-soluble ink connecting materials in China, it can be foreseen that in the next few years, polyurethane and alcohol-soluble inks will have a leap forward in the development of ink products for the majority of ink manufacturers. International competition, competing for market opportunities, creating favorable preconditions, and bringing considerable economic and social benefits to the majority of ink manufacturers, further promoting the development of China's printing and packaging environmental protection business.
