gravure printing ink used in China now contains a large amount of organic solvents (about 50%).Toluene, ethyl acetate, butyone and other solvents are low boiling point, high volatilization, containing aromatic hydrocarbon, both toxic and flammable, which is the main source of environmental pollution.

Printing gravure ink, usually made of chlorinated polymer.in the process of printing ink, chlorinated polymers need to use strong solvents (such as toluene and other aromatic solvents) to dissolve and to regulate the viscosity of ink in the process of printing.Chlorofluorocarbons that evaporate in the production of chlorinated polymer ink can destroy the ozone layer.in the process of printing, the use of aromatic solvents (toluene) can be harmful to workers' health and safety (fire hazard).in addition, ink solvent residue in packaging products is a concern.Benzene residue easily in the drying of printing ink film layer (low speed printing need to adjust the ink drying speed with xylene, can be more easily xylene residue), benzene residues can contaminate food or things in the packaging.Although it is the leader of alcohol soluble ink, although there is no phenylketone but still can pollute the environment, there will be solvent residue.

Plastic gravure printing ink production is being hereby, labor safety and health law and other laws and regulations, so be positive development and application to meet the requirements of environmental protection green gravure printing ink or water-based ink will become an inevitable trend.Water-based gravure printing ink as an alternative system of solvent ink has attracted the attention of various departments, and the water-based ink in packaging film printing is also developing vigorously.
