摘　　要：作为包装膜,双向拉伸聚丙烯(BOPP)已广泛应用于卷烟包装领域中。本研究通过设置标准环境和4种非标准环境,对不同型号的烟用BOPP膜进行了详细的处理研究,明确了环境温湿度对BOPP包装膜包括摩擦性能、热封性能、热收缩性能和力学性能4种上机适应性的影响趋势。通过理论计算和分子动力学模拟的方法,验证了烟用BOPP膜在异常温湿度下性能的劣化机制。结果表明,烟用BOPP膜上机适应性均受环境温湿度影响较大。因此,在储存和运输环节应尽量避免异常温湿度,并在性能检测和上机卷接包前进行标准环境的稳定处理。本研究对于企业提高效率和质量控制有重要参考意义。Biaxially oriented polypropylene(BOPP),as a type of packaging film,has been widely used in the field of cigarette packaging.In this study,by setting standard environment and 4 non-standard environments,different types of tobacco BOPP film were treated in detail,and the influence trend and degree of environmental temperature and humidity on the four kinds of machine adaptability of BOPP packaging film,including friction performance,heat sealing performance,thermal shrinkage performance and mechanical properties were clarified.What’s more,the degradation mechanism of BOPP film under abnormal temperature and humidity was verified by theoretical calculation and molecular dynamics simulation.The results showed that it can be seen that the adaptability of cigarette BOPP film on the machine is greatly affected by environmental temperature and humidity.Therefore,abnormal temperature and humidity should be avoided as much as possible during storage and transportation,and a stable standard environment should be maintained before performance testing and machine winding and packaging.This study has a great significance for enterprises to improve efficiency and quality control.
