Research on life cycle assessment of film-laminated steel packaging

The environmental issues associated with packaging materials have been attracting increasing attention. Life cycle assessment (LCA) is currently the main method used worldwide for evaluating green packaging materials. In this study, the LCA method was used to evaluate the environmental impact of Baosteel's newly developed process for manufacturing film-laminated steel packaging materials, from raw material mining, production, and processing to their storage, consumption, recycling, and final disposal. The environmental performance and main influencing factors were anayzed and compared. In addition, the life cycle environmental characteristics of film-laminated steel cans, tin-plated steel cans, and aluminum cans were compaed. Of the man environmental indicators of the life cycle of the film-laminated steel can, the environment load of the substrate accounts for the lagest proportion, followed by electricity. The environmental impact of the production of film materials cannot be ignored. The overall environmental performance of film-laminated steel cans is better than that of aluminum cans.
