摘　　要：采用全生命周期评价方法对宝钢新开发的覆膜铁金属包装材料从原材料采集、生产加工、流通储存、消费使用、循环利用到最终废弃的整个生命周期全过程进行了环境影响评价。分析了覆膜铁罐的环境绩效及其主要影响因素,比较了覆膜铁包装罐与镀锡涂料罐、铝涂料罐的全生命周期环境特性。在覆膜铁罐全生命周期主要环境指标中,基板的环境负荷占比最大,其次是电力。覆膜用的薄膜材料的生产对环境的影响不容忽视。覆膜铁罐主要环境绩效表现要优于铝涂料罐。Life cycle assessment(LCA)method is used to evaluate the environmental impact of Baosteel’s newly developed film-laminated steel packaging materials from the raw material mining,production and processing,circulation storage,consumption use,recycling and final disposal.The environmental performance and main influencing factors of film-laminated steel cans were analyzed and compared.The life cycle environmental characteristics of film-laminated steel cans,tinplate steel cans and aluminum cans were compared.In the main environmental indicators of the film-laminated steel can life cycle,the environmental load of the substrate accounts for the largest proportion,followed by electricity.The environmental impact of the production of film materials cannot be ignored.The main environmental performance of film-laminated steel cans is better than that of aluminum cans.
