The work aims to study the environmental impact of customized cat eye carton production, and to provide a reference for environmental impact assessment and process improvement of this type of packaging materials. The life cycle assessment (LCA) method was used to qualitatively and quantitatively analyze its impact on the environment (including 9 environmental factors). On the e-Footprint software, all life cycle assessments were completed online, including modeling, calculation analysis, data quality assessment and LCA results release. This type of product had a greater impact on primary energy consumption, water consumption and climate change. Each carton consumed 0.71 MJ of primary energy and 0.35 kg of water, and emitted 0.05 kg of gases that affected climate change. Among them, white cardboard and customized cat eye masks accounted for 37% and 35% of primary energy consumption, 79% of water consumption came from white cardboard production, and 29% and 25% of emissions to climate change gases, respectively. By optimizing the material, structure and production process of white cardboard and customized cat eye film, the energy consumption (including primary energy and water resources) of customized cat eye carton can be reduced and greenhouse gas emissions can be reduced.
