【摘要】 目的 基于烟草商业物流实际场景需求，探究烟草商业物流可降解薄膜缠绕包装的运输可靠性，为烟草商业物流包装的绿色转型和推广应用提供参考。方法 结合西安市烟草公司卷烟物流配送中心的调研数据，以低密度聚乙烯（LDPE）薄膜热缩包装为对照，利用ANSYS有限元分析软件对可降解薄膜缠绕包装进行静力学分析和随机振动模拟。结果 在相同静态载荷作用下，可降解薄膜缠绕包装的最大变形量约为LDPE薄膜热缩包装的1/5。水平随机振动对烟包顶部薄膜的影响较大，可降解薄膜缠绕包装的变形量小于LDPE薄膜热缩包装；垂直振动中薄膜变形主要集中在烟包中部，可降解薄膜缠绕包装的最大变形量仅为LDPE薄膜热缩包装的1/3。结论 仿真模拟结果证实，可降解薄膜缠绕包装的运输可靠性优于LDPE薄膜热缩包装，研究结论可为卷烟物流包装的工艺升级和绿色转型提供理论支持和方法参考。更多还原

【Abstract】 The work aims to clarify the transport reliability of wrapping packaging with degradable film for tobacco commercial logistics based on the current scenario of tobacco commercial logistics, so as to provide reference for green transformation and extensive application of tobacco commercial logistics packaging. Taking LDPE film shrink packaging as comparison, ANSYS finite element analysis software was introduced in the static analysis and random vibration simulation of degradable film wrapping packaging, based on the survey data from Xi’an Tobacco Logistics Distribution Center. The results showed that the maximum deformation amount of degradable films in wrapping packaging accounted for 1/5 of that in LDPE film shrink packaging under the same static load. In the horizontal random vibration simulation,the film on the top of the cigarette packs was the most vulnerable to vibration, and degradable films in wrapping packaging exhibited less deformation compared with LDPE film shrink packaging. And film deformation in the vertical random vibration mainly existed on the middle part of the cigarette pack, and the maximum deformation of degradable films in wrapping packaging was only 1/3 of that in LDPE film shrink packaging. In conclusion, the transport reliability of degradable film wrapping packaging is superior to LDPE film shrink packaging. The work may provide theoretical support and methodological reference for the process upgradation and green transformation of tobacco commercial logistics packaging.更多还原
