【摘要】：在人类生产生活过程中,时时离不开物流,而物流所依赖的重要技术手段之一即是缓冲包装。缓冲包装使用寿命极短,用量巨大,其生产和使用导致了越来越多的环境问题。2007年中国包装工业碳排放量为18379.2l万t,约占全国总排放量的2.74%,高于2.43%的GDP比重。大量二氧化碳等温室气体排放,直接造成全球气候变暖、雾霾等环境恶化。随着2008年“碳足迹”概念的提出,发展低碳经济、节能减排已逐渐成为社会各界共识,调查显示,每年我国有将近百亿美元的商品因不符合发达国家特定的包装标准而导致出口而受到直接或间接的影响。可见,低碳包装已成为国际上隐形的绿色贸易壁垒。作为包装业的重要支链——缓冲包装产业必然要掀起一场绿色低碳化设计革命。本课题依据生命周期评价方法论,建立缓冲包装碳足迹分析体系,并将其与传统缓冲包装设计程序相结合,构建新型缓冲包装优化设计模型。研究中,缓冲包装碳排放分析包含直接碳排放和间接碳排放的计算分析。缓冲包装碳足迹分析体系是以系统分析为出发点,主要涵盖了对缓冲包装材料的种类、缓冲包装材料的使用量、缓冲包装结构设计及其生产制造和使用等过程碳排放计量四大方面的分析,从而进一步完善传统缓冲包装设计方法。该模型能够在实际设计过程中具体考虑比较不同种类缓冲包装材料及其缓冲包装结构设计在防振缓冲性能、环保性能、经济成本、便于生产等方面的差异,以明确的量化指标为设计者和使用者提供更清晰的方案优化选择指导。本文对所提出的新型缓冲包装优化设计模型进行了验证试验,具体以缓冲包装用量很大的电子产品—一笔记本电脑(LenvonG450T4300)缓冲包装设计为研究对象,采用该优化设计模型对两种传统意义上皆可行的缓冲包装设计方案进行了比较分析,并得出明确结论。方案Ⅰ采用的缓冲包装材料为瓦楞纸板(B-200/135/200g/m2),面纸使用量为0.5m2,芯纸使用量为0.34m2；缓冲包装结构设计为插板格挡局部缓冲；瓦楞纸板重量为145.9g；一套瓦楞纸板缓冲设计产生的碳排放量为0.234kg；经济成本为0.342元人民币。方案Ⅱ采用的缓冲包装材料为EPE(30g/cm3),使用量为0.48cm3；缓冲包装结构设计为四角局部缓冲；EPE的重量为194.4g；一套EPE缓冲衬垫产生的碳排放量为0.306kg；经济成本为0.88元人民币。通过综合分析比较两种缓冲包装方案的保护性、环保性、综合效益,优选出方案Ⅰ为更佳方案,其不但满足保护内装产品及大量实际生产要求,还具有经济成本和低碳绿色环保的市场优势。
[Abstract]:In the process of human production and life, logistics is always inseparable from logistics, and one of the important technological means of logistics is cushioning packaging. The life of cushioning packaging is very short and the consumption is huge. The production and use of cushioning packaging have caused more and more environmental problems. In 2007, the carbon emission of packaging industry in China was 18379.21 million tons, accounting for 2.74% of the total national emissions, which is higher than 2.43% of GDP. A large amount of carbon dioxide and other greenhouse gas emissions directly cause global warming, haze and other environmental degradation. With the introduction of the concept of "carbon footprint" in 2008, the development of low-carbon economy, energy saving and emission reduction has gradually become the consensus of all walks of life. Every year, nearly ten billion dollars of goods in China are directly or indirectly affected by exports because they do not meet the specific packaging standards of developed countries. Visible, low-carbon packaging has become an invisible international green trade barriers. As an important branch of packaging industry, buffer packaging industry is bound to set off a green low-carbonization design revolution. According to the methodology of life cycle evaluation, the paper establishes the carbon footprint analysis system of cushioning packaging, and combines it with the traditional cushioning package design program to construct a new optimal design model of cushioning packaging. In the study, the carbon emission analysis of cushioning packaging includes direct carbon emissions and indirect carbon emissions. The carbon-footprint analysis system of cushioning packaging is based on systematic analysis. It mainly covers the types of cushioning packaging materials and the amount of cushioning packaging materials used. Four aspects of carbon emission measurement in the process of design, manufacture and use of cushioning packaging are analyzed in order to perfect the traditional design method of cushioning packaging. The model can consider the difference of different kinds of cushioning packaging materials and their cushioning packaging structure design in the aspects of anti-vibration buffer performance, environmental protection performance, economic cost, convenient production and so on in the actual design process. A clear quantitative indicator is used to provide designers and users with clearer guidance for optimal selection of schemes. In this paper, the optimized design model of the new cushioning packaging is tested, and the design of the cushioning packaging is studied with a notebook computer, Lenvon G450T4300, which is an electronic product with a large amount of cushioning packaging. The optimal design model is used to compare and analyze the two traditional cushioning package design schemes, and a clear conclusion is drawn. The cushioning packaging materials used in scheme I are corrugated board B-200 / 135g / m2 / 200g / m2, the amount of tissue paper used is 0.5m2, and the amount of core paper is 0.34m2.The cushioning packaging structure is designed to block the local buffer of corrugated board. The weight of corrugated board is 145.9 g, the carbon emission from a corrugated board buffer design is 0.234 kg, and the economic cost is 0.342 yuan. The cushioning packaging material used in scheme 鈪，
