| 中文摘要: |
| 目的 卷烟包装的阻隔性能是卷烟产品品质稳定性的关键影响因素，研究干燥环境中卷烟多层包装对水分阻隔的作用。方法 利用自主研发测试系统——动态水分分析气候箱，考察不同盒包在特定温湿度条件下水分扩散过程，计算水分扩散通量，并对包装阻湿性能进行量化表征。结果 建立的烟盒多层包装水分阻隔性能评价方法可准确量化表征包装的阻湿性能。低湿条件下，水分从烟盒包装各层空隙及材料的透过量各有差异，对于Bopp膜，60%以上的水分主要从材料扩散，对于不同商标纸和内衬纸，水分从材料及空隙扩散的分配比不同。对于整体包装水分阻隔性能，三层材料中Bopp膜对烟支水分稳定性作用的占比达90%以上，硬包优于软包。准确预测了烟支在不同盒包中水分的散失速率，低湿条件下，硬包卷烟的水分散失速率明显低于软盒卷烟的。结语 文中建立了多层烟盒包装阻湿性测试及评价方法，量化表征了卷烟盒包各包装层及不同部位对水分的阻隔作用，明晰了烟盒包装中影响卷烟水分稳定性的重要因素。 |

| The work aims to study the effect of cigarette multi-layer packaging on moisture barrier in a dry environment in view of that the barrier performance of cigarette packaging plays a key role in the quality stability of cigarette products. A self-developed testing system, dynamic moisture analysis climate box, was employed to investigate the moisture diffusion process of different packaging materials under specific temperature and humidity conditions, calculate the moisture transmission rate and quantitatively characterize the moisture barrier performance of packaging materials. The evaluation method of moisture barrier performance of multi-layer packaging of cigarette packet could accurately quantify and characterize the moisture barrier performance of the packaging. Under low humidity conditions, the amounts of moisture permeating through the clearances and materials of each layer of the cigarette packaging were different. For Bopp film, more than 60% of the moisture mainly diffused through the material. For different label paper and lining paper, the distribution ratios of moisture diffusing through the material and the clearances were different. For the moisture barrier performance of the overall packaging, the Bopp film played a decisive role in the moisture stability of cigarette, of which the contribution was above 90%. The moisture barrier performance of hard packaging was better than that of the soft packaging. The moisture diffusion rate of cigarette in different packaging was predicted accurately. Under low humidity condition, the moisture diffusion rate of hard-packed cigarette was significantly lower than that of soft-packed cigarette. The moisture barrier test and evaluation method of cigarette multi-layer packaging are established. The moisture barrier performance of each layer and different parts of cigarette packet is quantitatively characterized. Finally, the key factors that affect the moisture stability of cigarette in packet are identified. |
