Abstract: Volatile organic compounds ( VOCs) emitted from the package printing and sticker printingindustries were determined by sorbent adsorption,thermal desorption and GC /MS. The emission charac-teristics were analyzed,and the treatment of exhaust gas by purification facility was investigated. The re-sults 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,isopro-panol,propyl acetate,ethanol,butanone,o /m/p -xylene,cyclohexanone,1 -decene and acetone. Themain 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 purifica-tion efficiency was more than 60%. Close-
