Water-based gravure ink is future trend

At present, gravure printing is the main printing method for plastic flexible packaging materials. The domestic gravure printing industry is huge, and there are many related printing companies. Most companies use solvent-based inks for printing, resulting in a large amount of VOCs emissions. In recent years, China’s environmental problems have become increasingly prominent, and the country and the government have issued a large number of policies to control the emission reduction of VOCs in the gravure printing industry. Among them, the "Technical Requirements for Environmental Labeling Products-Gravure Printing Inks and Flexo Printing Inks (Draft for Comment)" clearly limits the VOCs of gravure printing inks to less than 5%, indicating the country and industry's direction and determination to environmental labels. Development of water-based gravure ink. Water-based gravure inks are still in the early stages of development, and the market usage is still very low, with a market size of only 370 million yuan.

Currently, there are two main types of domestic water-based gravure ink manufacturers. One is traditional water-based gravure ink manufacturers, such as Shanxi Jinghua Technology Industry and Trade Co., Ltd., Shenzhen Bright Ink Coating Co., Ltd., and Tianjin Jinquxin Trading Co., Ltd. And Xiamen Yitong Water Ink Co., Ltd., these companies have been involved in water-based gravure inks earlier, and water-based ink products are mainly surface printing inks;

The other is represented by large domestic ink companies such as Bauhinia, Letong Chemical and Guangdong Tianlong. These companies have large capacity for solvent-based gravure inks and high domestic brand awareness. In recent years, driven by policies, they have begun to get involved in the research and development of water-based gravure inks. It has strong research and development strength in domestic water-based gravure printing inks.

Although the country and the government strongly encourage the development and application of water-based gravure inks, compared with solvent-based inks in the plastic film printing process, water-based gravure inks still have slow printing speeds, high reprinting costs, and duplication. Wash dishes, etc. Moreover, there are not many mature products in the domestic water-based gravure ink market, especially water-based gravure inks. Domestic development time is short. Only a few companies can produce products, and most companies need to add 5%-30% ethanol. Dissolve and dilute the resin system.

On the whole, the development time of water-based gravure inks inChinais short, the industry lacks clear standards, and different companies have different definitions of water-based gravure inks. There are three mainstream standards for water-based gravure inks, one is pure water-based gravure inks without any solvent; one is that the ethanol content is within 5%; the last is that the ethanol content is within 30%. At present, the three major domestic standard gravure inks have a certain market space. In the future, with the continuous improvement of related technologies and processes, the market share of low-solvent gravure inks and pure water-based gravure inks will continue to increase. An important trend in the development of gravure inks.

In the printing industry, thermosetting inks are becoming more and more respected, thanks to their diversity, (various printing effects can be changed), simple, convenient, easy to store, environmentally friendly, and pollution-free. Etc.
