Volatile organic compounds (VOCs) emitted from the package printing and sticker printing industries were determined by sorbent adsorption, thermal desorption and GC/MS. The emission characteristics were analyzed, and the treatment of exhaust gas by purification facility was investigated. The results showed that the VOCs emitted during the printing process were mainly from the ink and thinner. The main components of VOCs emitted from the package printing project were ethyl acetate, isopropanol, propyl acetate, ethanol,butanone, o/m/p -xylene, cyclohexanone, 1-decene and acetone. The main components of VOCs emitted from the sticker printing project were isopropanol, propanol, acetone, toluene, dichloromethane and ethyl acetate. The VOCs exhaust treated by "UV photo-oxygen catalysis+two-stage activated carbon adsorption" could meet the VOCs emission requirements, and the purification efficiency was more than 60%.
