摘要
目的寻求一种包装设计中进行绿色选材的理论与方法。方法基于生命周期设计,通过对材料的功能性、经济性和环境友好性分析,讨论包装物料的循环模式,构建绿色包装材料选择的经济性评价模型,并以一次性饮料杯为例进行了分析验证。结果列出了不同模式下材料特性优先考虑等级,给出了材料的环境友好性对选材的影响指数,以及绿色选材的TOPSIS法解析最优解算法与综合性评价方法。结论采用TOPSIS法对经济性成本模型及生命周期环境影响指数进行综合求解,有利于从多种符合生命周期物料循环模式和材料特性关注等级的材料中选择较优材料。
The aim of this work was to propose the theory and method for selection of green materials in package design. Based on the life cycle design, the functionality, economy and environmental benefits of materials were analyzed, the recycle patterns of package materials was discussed, and the economy evaluation model for selecting green packaging materials was constructed. Material selection of a disposable beverage cup was illustrated as an example using the proposed method. The priority levels of material characteristics selection under different modes were listed in the aspect of functionality. The impact factors on material selection according to environmental benefits were put forward. A TOPSIS algorithm was proposed to obtain optimal solution and comprehensive assessment of green packaging＇ s material selection. In conclusion, getting the comprehensive solution of economic cost model and environmental benefits using the TOPSIS algorithm was beneficial for the selection of the best one from many materials which tally with life-cycle of material circulation model and priority level of material characteristics selection.
