This paper presents the raw material composition and VOC treatment status of the packaging and printing industry in Zhejiang Province based on the survey data obtained in 2015 of 254 packaging and printing enterprises. To analyze the emission characteristics and calculate the emission coefficients of the packaging and printing industry, 100 typical enterprises were further screened according to different printing processes. The results showed that about two-thirds of packaging and printing enterprises failed to effectively dispose of VOCs; meanwhile, solvent-based materials were still commonly used in the packaging and printing industry. The main emission pollution factors of VOCs in the packaging and printing industry were ethyl acetate, isopropanol, ethanol, propyl acetate, and -butyl acetate. The VOC emission coefficient of the packaging and printing industry in Zhejiang Province was 0.485 kg·kg, of which the gravure printing was the primary source with VOCs emission coefficient of 0.634 kg·kg. Compared with the material balance method, the error value from the emission coefficient method was less than 15%.
本文基于2015年对254家包装印刷企业的调查数据，介绍了浙江省包装印刷行业的原材料成分及挥发性有机化合物（VOC）处理状况。为分析包装印刷行业的排放特征并计算排放系数，根据不同印刷工艺进一步筛选出100家典型企业。结果表明，约三分之二的包装印刷企业未能有效处理挥发性有机化合物；与此同时，溶剂型材料在包装印刷行业仍被普遍使用。包装印刷行业挥发性有机化合物的主要排放污染因子为乙酸乙酯、异丙醇、乙醇、乙酸丙酯和乙酸丁酯。浙江省包装印刷行业的挥发性有机化合物排放系数为0.485千克/千克，其中凹版印刷是主要排放源，挥发性有机化合物排放系数为0.634千克/千克。与物料平衡法相比，排放系数法的误差值小于15%。
