摘　　要：本文从残留溶剂分析、BOPP薄膜微观结构分析、软包装设计(图文设计和软包装结构设计)、油墨、胶黏剂、印刷及干式复合工艺控制及环境等多方面对BOPP薄膜印刷复合后的溶剂残留进行分析。结果表明BOPP印刷复合膜在生产过程中易溶剂残留超标,尤其是对乙酸乙酯和甲苯等有机溶剂。因此减少有机溶剂的使用,如使用醇性或水性油墨,采用无溶剂复合等,或对BOPP材料进行改性,再配合工艺控制方法使溶剂残留量符合GB/T10004-2008的要求。This article analyzed the residual solvent of the flexible package from the kind of solvent, the microstructure of the BOPP, the design of printing pictures and the structure of the film, ink, adhesive and the control of printing and dry lamination process, and the environment of the workshop. Results BOPP for printing is easy to be elevated with organic solvent, especially ethyl acetate and toluene. The results show that we can reduce the use of organic solvent, especially using alcohol or water-based ink and vent free composite ect, or or modify the structure of the BOPP, and cooperate with the process control to accord with the GB/T10004-2008.
