The hottest polyurethane ink binder passed the ide

Recently, the polyurethane ink connecting material developed by Zhongshan Xinhui chemical products Co., Ltd. in Guangdong Province has passed the provincial scientific and technological achievements, so that the hot samples such as films can be as easy to control as heavy injection molding parts. This is the first successfully developed one in China, which has contributed to the rapid development of China's printing and packaging industry

in recent years, China's printing and packaging industry has developed rapidly, and the demand for printing ink has been rising. So far, the amount of gravure printing ink used in plastic printing and packaging and large bags outside small bags in China has exceeded 50000 tons/year, while most of the gravure printing inks used in plastic printing and packaging in China today are polyamide and chlorinated polypropylene system inks containing benzene solvents. Because benzene solvent is a kind of toxic substance, the printing ink containing benzene solvent releases toxic substances in the process of production, manufacture and use, polluting the air and endangering people's health. It has been banned in Europe, the United States and other countries and regions, and replaced by green environmental protection printing ink products. In addition, because polyester film has good tensile strength, temperature resistance, gas resistance and low hygroscopicity, it is widely used in plastic composite packaging. In China, the demand for polyester film is increasing at a rate of 15% per year. As we all know, chlorinated polypropylene ink is difficult to meet the printing requirements of polyester film. Therefore, it is widely used in printing and packaging in western advanced and developed countries, Polyurethane, alcohol soluble ink with strong adaptability and meeting the requirements of environmental protection and food hygiene. With China's accession to the WTO, many domestic printing and packaging manufacturers have developed new packaging and printing material products that comply with policies and regulations, environmental protection, industrial health, and resource policies and regulations in order to enter the international market and integrate their products with international standards. Polyurethane and alcohol soluble inks that meet the requirements of environmental protection and food hygiene are increasingly used in the printing and packaging of food and drugs, and the market prospect is broad. However, at present, the ink connecting materials for the production of polyurethane ink and alcohol soluble ink mainly rely on imports. The imported polyurethane and alcohol soluble ink connecting materials are expensive, and the country needs to spend a lot of foreign exchange to buy, resulting in high production costs; Moreover, the imported alcohol soluble ink should be adjusted according to its situation. The verticality of the main shaft and the test platform, and the coaxiality of the main shaft axis and the lifting screw axis. Most of the connecting materials are nitrocellulose, which is extremely inconvenient to use and produce, with narrow adaptability and unreasonable performance. It is one of the main factors that make polyurethane and alcohol soluble ink difficult to popularize in our country

xh-ibpu series polyurethane and alcohol soluble ink connecting materials developed by Xinhui company with high cost and in accordance with foreign advanced technical standards are especially suitable for the printing and packaging of food and drugs, and are widely used in the high-speed and low-speed printing of plastic flexible packaging composites such as pet, NY, BOPP, PE, etc. Its printing products have very good adhesion, good gloss and strong transparency. Compared with the ink produced by the chlorinated polypropylene ink connector currently used in the market, it has wider printing applicability, superior performance and affordable price, which can be completely comparable with imported products. The ink produced by xh-ibpu series polyurethane and alcohol soluble ink connector has considerable market competitive advantages compared with imported similar products, It is an ideal connecting material for replacing and eliminating chlorinated polypropylene ink. With the continuous development and application of polyurethane and alcohol soluble ink connecting materials in China, it can be predicted that polyurethane and alcohol soluble ink will have a rapid development in China in the next few years, which will bring considerable economic and social benefits to the majority of ink manufacturers by upgrading their ink products, participating in international competition, competing for market opportunities, creating good preconditions, and bringing considerable economic and social benefits to the majority of ink manufacturers, Further promote the development of printing and packaging environmental protection in China
