目的 针对卷烟企业生产过程中出现的烟用双向拉伸聚丙烯(Biaxially Oriented Polypropylene，BOPP)包装膜因喷码油墨易发生迁移而污染内侧纸盒的问题，明确问题成因，找到控制薄膜质量的关键检测指标。方法 对影响烟用BOPP包装膜透墨性能的相关质量指标如薄膜的化学组成、厚度、水蒸气透过量、氧气透过量、薄膜接触角、表面微观形貌特征等进行系统研究，对比透墨烟膜与正常烟膜相同检测指标的差异。结果 薄膜的厚度、接触角、水蒸气透过量、氧气透过量等指标对于烟用BOPP包装膜的抗油墨透过性能具有重要影响，薄膜上的微小孔洞是油墨发生透膜迁移从而污染纸盒的主要原因。结论 可以将烟用BOPP包装膜的接触角、水蒸气透过量及氧气透过量作为薄膜生产厂家出厂检验或卷烟企业入库的质量控制指标。

The work aims to solve the problem that the inner carton is likely to be contaminated by the migration of ink and clarify the key detection indicators for controlling the quality of (Biaxially Oriented Polypropylene) BOPP cigarette packaging films. The related quality indicators affecting the ink permeability of BOPP cigarette packaging films such as chemical composition, thickness, water vapor permeability, oxygen permeability, contact angle of films and surface microstructure characteristics were systematically studied. The difference of the same detection indicators between ink-permeable BOPP cigarette packaging films and normal films was compared and analyzed. The results showed that the thickness, contact angle, water vapor permeability, oxygen permeability and other indicators had an important effect on the ink penetration resistance of BOPP cigarette packaging films, and the tiny holes in the films were the main reason for the ink to migrate through the films and contaminate the cartons. The contact angle, water vapor permeability and oxygen permeability of BOPP cigarette packaging films can be used as quality control indicators for the inspection of film manufacturers or the cigarette enterprises.
