Date: Oct 17 2023 From: Star Color
With the continuous improvement of environmental protection and health awareness, water-based ink has gradually become an important choice for the printing industry.Especially in the field of plastic film printing, water-based flexographic printing ink has been more and more widely used by virtue of its unique characteristics and advantages.In this paper, the characteristics and advantages of waterborne flexographic printing inks for plastic film will be deeply analyzed.
Characteristics of water-based flexographic printing inks
1.Environmentally：The biggest feature of water-based flexographic printing ink is environmental protection.Because it uses water as a solvent, rather than an organic solvent, it reduces emissions of VOCs (organic volatile compounds) during the printing process, reducing the impact on air quality and human health.
2.Safety：Another feature of waterborne flexographic inks is safety.Because it does not contain organic solvents, the risk of combustion and explosion is low, reducing the possibility of accidents.
3.Printability：Waterborne flexographic printing ink has good wettability and adhesion, and can be printed on a variety of plastic films, including PE, PP, PET ，etc.（for example，
Water-based BOPP plastic ink）In addition, its leveling and drying properties also ensure the smooth progress of printing.
4.Full color：Water-based flexographic printing inks can provide bright, full color effects, making prints more attractive.
5.Water resistance and friction resistance：Most water-based flexographic printing inks have good water resistance and friction resistance, which can meet the needs of general packaging and decoration.
Advantages of water-based flexographic printing inks
1.Cost reduction：Although the manufacturing cost of water-based flexographic printing inks is higher, it uses fewer organic solvents, reducing raw material costs and waste disposal costs.In addition, due to its good drying performance and printing adaptability, energy consumption and production costs are also reduced.
2.Increase productivity：Waterborne flexographic printing ink has better leveling and drying performance, which can reduce downtime and waste in the printing process and improve production efficiency.
3.Expand application scope：Due to the good environmental protection and safety of water-based flexographic printing ink, it has been widely used in some specific fields, such as food packaging, pharmaceutical packaging，etc.
4.Reduce the impact on the environment：Because water-based flexographic inks use water as a solvent, VOCs emissions are reduced during the printing process, reducing the impact on the environment.In addition, it does not contain organic solvents, which also reduces environmental problems such as exhaust gas treatment and hazardous waste disposal.
5.High customization possibility：The production process of water-based flexographic printing ink makes it highly customizable.According to the specific needs of customers, the viscosity, color, weather resistance and other parameters of the ink can be adjusted to meet the application needs of different fields.
6.High precision printing：Because flexographic printing is a printing method between offset printing and intaglio printing, its printing accuracy is higher than intaglio printing, and it can print more delicate images and richer colors.This makes water-based flexographic printing inks have significant advantages in certain high-precision printing fields, such as food packaging, anti-counterfeiting labels, etc.
Future development trends
1.Technological innovation：With the continuous progress of science and technology, more technological innovations will be applied to the production and printing process of water-based flexographic printing inks in the future.For example, nanotechnology can be used to improve ink particle size and distribution and improve printing quality；Biotechnology can be used to develop more environmentally friendly and sustainable water-based inks.
2.Sustainability：With the increasing global awareness of environmental protection, the future of water-based flexographic printing inks will focus more on sustainability.For example, renewable resources can be used as raw materials to produce water-based ink, reducing the burden on the environment；At the same time, water-based inks with low volatile organic compound emissions can be developed to further reduce the environmental impact.
3.Personalization and Functionality：In the future, consumers' personalized needs for packaging and products will continue to increase, which will promote the development of water-based flexographic printing inks to diversification and functionality.For example, specific functional components can be added to the ink to achieve anti-counterfeiting, antibacterial, fresh-keeping and other functions to improve the added value of the product.
4.Industry integration：With the intensification of market competition and the strengthening of environmental protection policies, the future water-based flexographic printing ink industry will be further integrated.Enterprises with technological advantages and brand influence will get better opportunities for development, while some backward and environmentally unfriendly production enterprises will be eliminated.
5.Expand application areas：With the progress of technology and the growth of market demand, the application field of water-based flexographic printing ink will continue to expand.
In the future packaging and printing industry, with the continuous improvement of environmental awareness, the application prospect of water-based flexographic printing ink will be broader.Let's work together to promote the green development of the packaging and printing industry.
