The work aims to solve the problems that existing packaging products do not comply with the green concept and lack uniform regulations and evaluation methods. A green packaging evaluation system was established. On the basis of FAHP (Fuzzy Analytic Hierarchy Process), the weights were determined according to the characteristics of each layer of indicators. 5 first-level indicators adopted the analytic hierarchy process, and 13 second-level indicators adopted the method of combining the expert weight coefficient with the entropy weight in consideration of subjectivity and objectivity. Finally, combined with green satisfaction questionnaire of packaging product, the fuzzy comprehensive evaluation was carried out to the packaging greenness to obtain an evaluation value of packaging greenness. A packaging factory situated in Yiwu City was used as an example for verification. 500 questionnaires were distributed and 432 were recovered. After calculation, an intuitive green evaluation value of 80.714 was obtained, and the evaluation level was excellent. The establishment of the evaluation indicator in this paper is scientific and reasonable, and the data adopted in the method are easy to obtain, with simple calculation process and accurate and intuitive results, which has certain theoretical and practical significance.
