| 摘要: |
| 目的 为了解决烟包产品表面出现的“水雾”问题，分析纸张、光油、印刷品表面的印刷膜层、内装物烟丝等烟包产品的原材料和印刷工艺对“水雾”现象的影响。方法 通过减量法找到产生“水雾”的来源，创新一种上光油体系，采用以物理和化学协同的方法排除“水雾”。结果 当纳米二氧化硅的质量分数为0.15%、防水雾剂质量分数为0.15%共同作用时，彻底消除了“水雾”，同时发现当印刷品表面平滑度值为8000～14 000 s时满足对产品的质量要求。结论 包装盒的纸板、印刷UV油墨、光油等是“水雾”的主要来源，外层包覆的BOPP膜的密封性和外界温度变化提供了“水雾”形成的环境，而通过测定印刷品表面平滑度值可以判定水雾是否出现。 |

| Abstract: |
| The work aims to solve the problem of "water mist" on the cigarette packet products, and analyze the effects of raw material of cigarette packet products (such as paper, varnish, printed film on the printed matter and cut tobacco) and printing technology on the "water mist". The sources of "water mist" were found by the weight loss method. The varnish system, with the use of physical-chemical synergy, was created to eliminate the "water mist". When the mass fraction of nano-silica was 0.15% and the mass fraction of anti-mist agent was 0.15%, the "water mist" was completely eliminated, and it was found that the product quality requirements were met when the surface smoothness of printed matter was 8000～14 000 s. The paperboards, printing UV ink and varnish, etc. of the packaging box are the sources of "water mist". The tightness of BOPP film coated on the outside and the change in external temperature provide the environment where the "water mist" is formed. It can be judged whether the water mist occurs by measuring the surface smoothness of printed matter. |
