基于白光干涉仪对卷烟包装材料外观质量的评价

目的 建立评价卷烟包装材料外观质量的检测方法，用于对卷烟包装材料的表面印刷适用性进行预判，以提高印刷效率。方法 以水雾面积作为对卷烟包装材料外观质量的主要评价对象，筛选卷烟包装材料印刷面的表观特性。对烟标表面粗糙度、平滑度、亮度、摩擦因数、粗糙度、表面形貌与水雾面积的相关性进行分析。结果 卷烟包装材料外观质量（水雾面积）与粗糙度、亮度等参数相关，与平滑度、摩擦因数等参数不直接相关。在433～818 nm的微观粗糙度内，水雾面积随着粗糙度的增加逐渐减小，当微观粗糙度大于818 nm时，水雾现象不存在。结论 基于白光干涉仪的微观粗糙度可作为卷烟包装材料外观质量（水雾现象）的定量和定性评价指标，该方法为解决烟包印刷行业的水雾问题提供了有益的理论支持。

Surface Quality Evaluation of Cigarette Packaging Materials Based on White Light Interferometer

A testing method for evaluating the appearance quality of cigarette packaging materials is established to predict the surface printing suitability of cigarette packaging materials to improve printing efficiency. Taking the area of water mist as the main evaluation object for the appearance quality of cigarette packaging materials, the appearance characteristics of the printing surface of cigarette packaging materials were screened. The correlation between the surface roughness, smoothness, brightness, friction coefficient, roughness, surface topography of cigarette labels and water mist area is analyzed in this work. The results show that the appearance quality of cigarette packaging materials (water mist area) is related to parameters such as roughness and brightness, but not directly related to parameters such as smoothness and friction coefficient. Within the micro-roughness of 433-818 nm, the water mist area gradually decreases with the increase of the roughness. When the micro-roughness is greater than 818 nm, water mist does not exist. The micro-roughness based on white light interferometer can be used as a quantitative and qualitative evaluation index for the appearance quality (water mist phenomenon) of cigarette packaging materials. This method provides a useful theoretical support for solving the water mist problem in the cigarette packet printing industry.
