Why advocate the production and use of water-based inks
Date: Aug 30 2023 From: Star Color
At present, water-based ink is mainly used in flexographic printing and gravure printing, and occupies a considerable proportion in food packaging, tobacco and alcohol packaging, children's toy packaging and other fields.With the gradual popularity of green and environmentally friendly packaging advocated in China, packaging and printing products with strict hygiene requirements such as cigarettes, alcohol, food, beverages, drugs, and children's toys will gradually adopt flexographic printing.Especially in the field of packaging printing, the proportion of flexographic printing will gradually increase, so the potential market for water-based ink in China is huge.
Because traditional coatings and inks use organic solvents as diluents, which contain a large number of volatile organic compounds VOCs, such as benzene, toluene, ethylbenzene, formaldehyde, methanol, ethylene glycol, etc., these substances cause harm to the human body through inhalation or skin contact.
Water-based ink is a new type of environmental protection product relative to traditional products, its principle is to replace the diluent in traditional products with water.Compared with traditional organic solvent-based inks, water-based inks have three major advantages:
First, the water-based ink itself VOCs content is low, greatly reducing VOC emissions, thereby reducing air pollution, it can almost eliminate the solvent-based ink to some toxic and harmful substances, eliminate the harm to the human body and the pollution of the packaged goods, improve the overall environmental quality, more healthy and environmental protection.
Second, because it is water to replace 30% to 70% of the toxic organic solvents in the traditional ink, so that the ink no longer contains volatile organic solvents, so in the printing process no adverse effects on the health of workers, no pollution to the atmospheric environment, reduce the risk of fire, improve safety.
Third, the products produced by using the water-based ink have bright colors;Excellent fastness to sunlight; Good acid and alkali resistance;
Convenient color matching,it has great advantages in viscosity, glossiness, coloring degree, drying speed, etc., making the quality packaging of water-based ink products more guaranteed.
Therefore, the use of water-based ink is advocated in many flexible packaging, and the variety of water-based ink is also constantly increasing. Its role is not only environmentally friendly and healthy, but also safe and practical,Therefore, it is necessary to vigorously promote the production and use of water-based ink.
