Printing and Packaging Industry

Including packaging printing, book and periodical printing, coating printing, etc. In the process of color printing and plastic film laminating, a large amount of solvent-based inks and diluent organic solvents are used. The exhaust gas has the characteristics of high air volume, low quality concentration, and complex composition. During ink drying, the concentration of exhaust gas in the workshop needs to be strictly controlled. Usually, a large air volume ventilation is introduced, so the emission air volume is large while the concentration is low.
