The work aims to provide a method to determine the importance of green packaging evaluation index based on AHP and entropy weight. Combined with the existing data, a multi-level green packaging evaluation index system was constructed from the four dimensions of environment, resources, economy and function. The subjective weight of each index was determined by AHP method, and the objective weight of each index was obtained by entropy weight method. Finally, the principle of combination weighting of multiplication was used to integrate both of them, and the comprehensive importance of each index was obtained. Calibration of quantitative importance achieved the effective ranking of green packaging evaluation indexes. It was concluded that the importance ranking of the first-level evaluation indexes of green packaging was resource index>environmental index>economic index>functional index. The top three of the second-level indexes were vacancy volume ratio, harmful ingredients in raw materials and packaging cost. The experts’ subjective preference and objective difference of evaluation index are combined better, and a more reasonable index weight is established by integrating AHP weight value and entropy weight value. The proposed method can provide effective reference for the formulation of green packaging evaluation system.
