The demand for ink market is gradually increasing, and environmentally friendly products are becoming the research and development direction

With the development of the packaging printing industry, the advancement of ink technology will drive the rapid development of ink. The demand for ink will continue to increase, and the production of ink will also continue to improve. The ink industry has great development space.
With the development of the economy, the packaging industry is growing rapidly. As an essential material for packaging pattern printing, the demand for ink is increasing day by day. However, due to its pollution to the environment and its impact on human health, it urgently needs to solve the problem of pollution.
Ink is an important material used for printing packaging materials. It expresses patterns and text on the substrate through printing. Ink includes main and auxiliary components, which are uniformly mixed and repeatedly rolled into a viscous gel like fluid. Composed of pigments, binders, additives, and solvents. Used for various printing purposes such as books, packaging decoration, and architectural decoration.
With the development of the packaging printing industry, the advancement of ink technology will drive the rapid development of ink. The demand for ink will continue to increase, and the production of ink will also continue to improve. The ink industry has great development space. However, currently the scale of ink enterprises in China is not large, and the market share of individual enterprises is not high; Weak technological innovation capability; The environmental friendliness of domestically produced ink is not strong; Insufficient supply of high-end products; The lack of ink technology talents and other serious obstacles have hindered the development of the ink industry. Therefore, the industry has taken a series of measures to strengthen and consolidate the development of the ink industry, such as increasing technological investment in the industry, strengthening the development of environmentally friendly inks, and focusing on independent innovation in ink research and development; Strengthening the research on ink theory and cultivating scientific and technological talents has achieved good results.
In addition, the development of environmentally friendly ink is also important. Looking at the world, food safety incidents are constantly emerging, with a large proportion caused by ink. The main culprit of ink pollution comes from the solvents it contains. The solvent plays an intermediary role in ink by bonding pigments and adhesives to printed materials. The working principle is to first mix the pigment and solvent, dissolve them into a liquid that can flow, and the liquid solvent evaporates and becomes a solid, thereby achieving the transfer and adhesion of the pigment to the printed matter. The volatility of solvents is an important source of pollution, which not only pollutes the air and endangers the health of workshop workers, but also causes secondary pollution to consumers if the solvents are not completely evaporated and stacked immediately after printing. Therefore, the research and application of environmentally friendly inks has become the main task of the ink industry today.
Environmentally friendly offset printing ink has been widely used in countries such as the United States and Japan, but its application in China is still quite limited due to technical factors, but the main reason is insufficient understanding. Environmentally friendly offset printing ink is mainly non aromatic soybean ink. The PAH (polycyclic aromatic hydrocarbons) contained in traditional ink components are volatile solvents that are harmful to human health; The volatile organic compounds contained in it not only increase air pollution, but also cause harm to human health. Offset soybean ink uses environmentally friendly soybean materials instead of some petroleum solvents, which can reduce environmental pollution and harm to human health.
At present, environmentally friendly inks mainly include water-based inks, UV inks, water-based UV inks, and some alcohol soluble inks. At present, China's printing industry is facing great environmental pressure. Due to the fact that most inks used in printing contain organic solvents (compared to solvent based inks, offset printing inks contain very few organic solvents), the volatilization and emission of organic solvents can cause environmental pollution. In addition, ink contains harmful heavy metal elements such as lead, chromium, cadmium, mercury, arsenic, and barium, which pose great harm to human health and the environment. From the perspective of environmental protection and health, more and more users consider low toxicity, environmental friendliness, and pollution-free as important conditions when choosing ink. In China, the development of environmentally friendly offset printing ink is still constrained by many factors, but for the Chinese ink industry, achieving and promoting green ink is the research goal and pursuit.
