The work aims to realize the selection of packaging materials for high-voltage electrical equipment, improve the consistency and economy of packaging materials selection, and reduce manufacturing costs. A multi-objective material selection model including five optimization objectives such as packaging bearing capacity, packaging reliability, packaging cost, resource consumption and packaging greenness was established. The evaluation index set was constructed with the combined membership function, and the material selection was realized by combining the grey crelational analysis (GRA) method with the fuzzy analytic hierarchy process (FAHP) based on the possibility ranking algorithm. The correlation coefficients of candidate materials were 0.745, 0.606, 0.669 and 0.749. The packaging material with the largest correlation coefficient is the final preferred packaging material.
