Printing ink industry development status and characteristics of China

Nowadays, with productivity increasing, during the improvement of printing machine in printing quality and efficiency, the requirement of ink performance, quality and function is becoming stricter. It also brings high demand for ink color purity, saturation, reduce ink film thickness, improve adhesion and gloss, and reduce energy consumption, the use of pollution-free and easy recycling materials in flexible packing application.

 

Flexible packaging printing ink is used to print in the "soft" packaging materials such as plastic film, bags, aluminum foil and roll wrapping paper and other printing process inks.

 

They can be divided into gravure inks, letterpress inks and flexographic inks by different print version. They can be divided into solvent-base inks, alcohol-base inks and water-base inks by different main ingredients of ink. It also can be divided into surface printing inks and inner printing ink by different print surfaces.

 

In daily use, the ink should not be faded or discolored by sunshine. It should have certain fastness; it will not fall down during friction with the packaging process in bending and generally shedding in the printing process, it should have good printability and adaptability,

The printing surface is not bonded with the other surface layer during roll; in terms of stability, it requires the ability to withstand the adhesive in composite solvents and packaging of pH, oil and other ingredients ,bear the heat caused in post-process and suit for cold and frozen storage. In addition, it also have requirement on detection viscosity, volatility, fineness which we can find on national standard.

Regard as environment protection, the most urgent topic is to solve the environment pollution during manufacturing and usage. Many developed countries have set strict regulations, and establish strong regulatory and monitoring agencies, and continue research and development of a wide range of effective solutions, such as the use of environmentally friendly materials, suppression and recovery of emissions and other harmful pollutants.
Chinese Ink Network data show that in 2006 the global ink market volume is approximately $ 15 billion. The output is about 3.6 million tons, of which 1.05 million tons in North America, 0.25million tons in South American, 1.2million tons in Europe, and 1.1million tons in Asia. Japan as the world's largest ink production and consumption country stands for the inks development in the world.
