目的 解决卷烟接装纸上机过程中出现的平整度及黏结问题，明确影响接装纸上机适用性关键指标的影响因素。方法 以接装纸为研究对象，通过改变控制环境温湿度条件，分析不同条件下接装纸的平整度变化，通过扫描电镜对表面微观结构进行分析，采用液体渗透法、动态渗透法、接触角法研究其相应的渗透特性及润湿性能，对不同供应商相同指标的差异性进行对比分析。结果 温湿度在20 ℃/50%至30 ℃/60%范围时，接装纸平整度小于5 mm，其自身的渗透性能及润湿性能受影响较小。结论 接装纸的上机适用性的关键指标平整度和黏结性不仅受到原纸和印刷工艺的影响，还受环境温湿度的影响。对不同工艺接装纸根据其渗透及润湿性能选配适合的接装胶，可以有效提高其上机适用性，减少材料损耗及质量缺陷。

The work aims to solve the problems of flatness and adhesion in the process of cigarette tipping paper loading and clarify the influencing factors that affect the key index of tipping paper loading applicability. With tipping paper as the research object, the change of tipping paper flatness under different conditions was analyzed by changing and controlling the ambient temperature and humidity. Then, the surface microstructure was investigated by scanning electron microscope, and the corresponding penetration characteristics and wetting performance were studied by liquid penetration method, dynamic penetration method and contact angle method. The difference in the same index for different suppliers was compared and analyzed. When the temperature and humidity were controlled within the range of 20 ℃/50% to 30 ℃/60%, the tipping paper flatness was less than 5 mm, and its own penetration and wetting performance was less affected. The key index of tipping paper loading applicability such as flatness and adhesion is not only affected by the base paper and printing process, but also by the ambient temperature and humidity. Selecting suitable tipping glue for tipping paper produced by different processes according to the penetration and wetting performance can effectively improve the loading applicability and reduce material loss and quality defects.
