运用价值工程推进适度包装

随着我国经济的发展,人民物质生活水平的迅速提高,商品包装在向高档化、礼品化、时尚化方向发展的同时,小商品大包装、过度包装、过剩包装现象日趋严重。本文运用价值工程原理探讨如何推进商品适度包装的问题,有重要的现实意义。     

光纤布拉格光栅(FBG)温度传感器增敏封装技术

介绍了光纤布拉格光栅(FBG)传感器测温的基本原理和封装方法,提出了一种新型的FBG温度传感器的封装技术,包括封装结构的设计及封装材料的合理选择,目的是提高FBG的温度敏感系数和消除应力的交叉影响。通过实验对裸光纤和封装后的光纤的温度特性、应力影响等进行了对比,结果表明:采用此法封装后的FBG对温度具有很好的线性度和重复性,基本上消除了应力的影响,可以准确监测温度,测温范围为-15~200℃,精度达到±0.05℃。     

聚乳酸薄膜表面SiOx层的制备与阻隔性研究

聚乳酸是一种可完全生物降解的新型绿色包装材料,由于其良好的物理机械性能、生物相容性、可吸收性及对人体和环境的无毒性等,广泛应用于各种包装领域。本研究利用等离子体增强化学气相沉积法在厚度为40μm的聚乳酸（PLA）基材上制备阻隔性能优良的SiOx层。制备的SiOx层无色透明且与基材附着牢固。实验分别采用FTIR、SEM和AFM对沉积的SiOx层进行结构和表面性能分析,以表面轮廓仪测量SiOx层厚度,以透氧仪和透湿仪表征SiOx层的阻隔性。结果表明：制备的SiOx层表面结构均匀致密,平均厚度为174nm,透氧率从原膜的167.52cm^3/（m^2·24h）降低到17.88cm^3/（m^2·24h）,透湿率从原膜的132.93g/（m^2·24h）降低到15.23g/（m^2·24h）,阻隔性能明显改善。     

Sustainable consumption and plastic packaging: Relationships among product involvement,perceived marketplace influence and choice behavior

This study examines the relationships among human value connotations (instrumental and terminal), product involvement, perceived marketplace influence, and choice behavior in the context of sustainable consumption. Data was collected from 612 urban Indian residents who regularly consume sustainable products, e.g., non-plastic packaging bags. The study operationalizes the partial least square structural equation modeling method in consort with the covariance-based structural equation modeling. The research demonstrates the direct impact of instrumental and terminal values on product involvement and the direct influence of product involvement on perceived marketplace influence towards plastic packaging-related choice behavior. It is pertinent to focus on both instrumental and terminal connotations of human values to augment product involvement for plastic packaging. Limited studies have examined the possible relationships between two distinct yet interconnected connotations of human values on product involvement and perceived marketplace influence in the context of sustainable consumption related to plastic packaging.     

A data-driven decision support system with smart packaging in grocery store supply chains during outbreaks

The unexpected emergence of the COVID-19 pandemic has changed how grocery shopping is done. The grocery retail stores need to ensure hygiene, quality, and safety concerns in-store shopping by providing “no-touch” smart packaging solutions for agri-food products. The benefit of smart packaging is to inform consumers about the freshness level of a packaged product without having direct contact. This paper proposes a data-driven decision support system that uses smart packaging as a smart product-service system to manage the sustainable grocery store supply chain during outbreaks to prevent food waste. The proposed model dynamically updates the price of a packaged perishable product depending on freshness level while reducing food waste and the number of rejected customers and maximising profit by increasing the inventory turnover rate of grocery stores. The model was tested on a hypothetical but realistic case study of a single product. The results of this study showed that stock capacities, freshness discount rate, freshness period, and quantity discounts significantly affect the performance of a grocery store supply chain during outbreaks.     

我国快递业包装碳排放问题分析与对策——以郑州市为例

从我国快递行业包装碳排放现状入手,首先从碳中和愿景角度对快递包装的政策实践、消耗量和现有回收模式问题进行分析。其次以郑州市为例,使用排放因子法对郑州2014-2020年的包装碳排放进行了测算,估算出2020年郑州快递包装碳排放为12.11万t。最后,对减少快递包装碳排放提出了评估快递企业碳排放绩效、提高包装回收率和透明行业碳排放数据的建议。     

安溪茶包装产业支持性配套建设发展研究

安溪茶包装产业依托其强大的茶叶生产能力与地理位置优势，得到了一定程度发展，但其发展进程中，支持性配套建设发展仍存在诸多亟待解决的问题：产业基础配套设施薄弱；行业协会管理不足，人力资源层次低，创新力不足；政府职能缺失等，这些问题对安溪茶包装产业的持久发展造成了威胁。针对上述问题，完善关联产业和支持性配套设施建设；组建行业协会，走联合集群之路，实现包装产业合力；产学结合，优化人才结构；发挥政府职能作用等措施势在必行。
