为了降低产品包装生命周期中形成的高度浪费和高碳排放,给出产品低碳包装概念设计的流程和方法,讨论低碳包装概念设计的准则和边界,以防护性、销售性、低碳性和经济性的综合优化准则为约束,建立产品低碳包装概念设计参数的主成分模型,该模型在集成和筛选原有设计信息的基础上通过数学降维的方式形成新的主成分以降低概念设计方案选择的难度,同时还建立包装概念设计阶段的碳足迹计算模型,给出低碳包装概念设计方案的评价和选择方法,以小型汽油机包装为例,在低碳包装概念设计方法指导下选择的木材、瓦楞纸板和胶合板作为汽油机包装材料形成的3个方案中,结果表明,瓦楞纸板在综合性能指标中以161.17的分值被确定为最优解,符合目前高强度瓦楞纸板代木包装在机电产品包装中的应用趋势,从而验证了此方法有效.
The proportion of carbon emissions in packaging industry has exceeded its proportion of output value in GDP, in order to reduce highly waste and carbon emissions in the life cycle of product packaging, a conceptual design processes and method of low-carbon packaging of products was provided, the guideline and boundary of conceptual design for low-carbon packaging was discussed. Under the constraint of com- prehensive optimization which integrated protection, merchantability, low-carbon and economy, the prin- cipal component model of conceptual design parameters for low-carbon packaging was analyzed, it's effec- tive to reduce dimensions of design parameters by mathematical way, the new principal component which integrated and filtered original design information and reduced the difficulty of design~ the carbon footprint calculation model of the conceptual design phase of product packaging was also discussed; the method of e- valuation and selection on conceptual design scenario for low-carbon packaging was established. The case study results of gasoline packaging show this method is effective through three scenarios including wood, corrugated cardboard and plywood in the low-carbon packaging concept design guidance, and the corruga- ted cardboard is determined to be the best solution because of its comprehensive performance indicators. 161.17. This result consistent with packaging trend of mechanical and electrical product which use high- strength corrugated cardboard instead of wood.
