Study On Optimization Design Method Of Cushioning Packaging Based On Carbon Footprint Analysis

Cushioning packaging is one of the important technology that logistics depend on, in the process of human production and life. As it services life shortly, instantly becomes garbage, its production and use led to a growing number of environmental problems. By 2007, carbon emissions of Chinese packaging industry chain is the 2.74%of the total carbon emissions, reaching 1837.921 million tons, more than 2.43%of the proportion of GDP M. Large amounts of carbon dioxide and other greenhouse gas emissions, directly contribute to global warming, haze, etc.. With the "carbon footprint" concept was advanced in 2008, the development of low carbon economy has gradually become a social common consensus. As shows, every year nearly tens of billions of dollars of goods our country cannot be exported due to not meeting the specific packaging standards of developed countries every year. Obviously, low carbon packaging has become the invisible green trade barriers, and cushioning packaging industry as an important branch of packaging industry must set off a green low carbon revolution.This thesis establishes carbon footprint analysis system for cushion packaging based on life cycle assessment method, and combines it with the traditional design procedure of cushioning package design processes, in order to establish optimization design model of cushioning packaging. In the study, cushioning packaging carbon analysis includes direct and indirect calculation of carbon emissions. Cushioning packaging carbon footprint analysis mainly begin with analyzes system as starting point, which covers kinds of cushion packaging materials, packaging material usage, the structure design of cushion packaging and cushioning packaging carbon emissions, so as to further improve the traditional methods of cushioning package design. The model can specific consider different types of cushion packaging materials and cushioning packaging structure design in the anti vibration cushion performance, environmental performance, economic cost, convenient production and other aspects of the differences in the actual design process, and offer clear quantified targets that guidance designers and users to select optimization scheme clearly.The paper verified the proposed optimization model of cushioning packaging design model by test, the research object was elected a notebook computer (LenvonG450T4300), as the cushion packaging amount of electronic product is huge, compared and analyzed the optimization design model of two that in general are feasible buffer packaging schemes based on the optimization design model, and draw a clear conclusion.Proposal one:cushioning packaging material is corrugated board (B-200/135/200g/m2), usage of paper is 0.5m2, usage of core paper is 0.34cm2; the structure design of cushioning packaging is inserting plate block local buffer; corrugated cardboard weight is 145.9g; carbon emissions of a set of corrugated cardboard cushion pad is 0.234kg; and cost is 0.34 yuan. Proposal two:cushioning packaging material is EPE (30kg/m3), usage of EPE is 0.48m3; the structure design of cushioning packaging is four local buffer; EPE weight is 194.4g; carbon emissions of a set of EPE cushion pad is 0.306kg; and cost is 0.88 yuan. Through analysis and comparison protection, environmental protection,comprehensive benefits of two kinds of cushion packaging scheme, optimizes the scheme I as better solutions, which not only meet the protection inside products and a large number of the actual production requirements, but also has market advantage on the economic cost and low carbon green environment.
