To explore the nature and evaluation method of humanistic packaging design, so as to provide the theoretical support and realization approach to evaluating and improving the level of humanistic design. By literature survey, theory refinement and logically reasoning, this paper analyzed and proposed the evaluation index system for humanistic packaging design, and built a quantitative model for evaluating the level of humanistic packaging design based on support vector machine (SVM). The results verified the feasibility and effectiveness of the SVM model. This model is of broad and practical application potential and provides the theoretical basis for improving the humanistic design level of product packaging.
