Purpose Life cycle assessment was used to compare and analyze the impact of the commonly used labels (PP/glassine and PP/PET), so as to provide certain suggestions for the development of green packaging. Design/methodology/approach In this study, SimaPro software was used to calculate and analyze the whole life cycle of labels from the stage of raw materials, processing and waste disposal. Findings Twelve environmental categories were used to quantitatively analyze the environmental impact of the two different labels. The results show that the impact of the production stage on the environment is greater than that of the material stage, and the least impact is seen in final disposal stage. Research limitations/implications During the post-processing stage of this study, PET was set for incineration, and glassine was 100% recycled. Practical implications Green packaging is the development trend of the future packaging, and follows the principle of 3R1D. According to the calculation results, corresponding suggestions can be put forward from production, processing, use, waste and other aspects, and make corresponding contributions to the development of green packaging. Originality/value The contribution and impact of each stage of the product on the environment can be studied. The environmental impact can be reduced through different solutions such as the use of green materials, good processing techniques and higher recycling rates.
