The work aims to explore how the psychological factors affect the public's willingness to accept green packaging. First, the public acceptance model of green packaging was constructed with reference to TPB theory, and then the questionnaire was prepared according to the model hypothesis for survey. Finally, the reliability and validity of the 417 questionnaires were analyzed. AMOS17.0 software was used to fit the sample data and the hypothetical model with the structural equation model. The consumers' perceived usefulness to green packaging, perception behavior control and environmental responsibility awareness were of a significant impact on the public acceptance of green packaging. There was a significant interaction between the three aspects of perceived ease of use, public awareness of environmental consequences and perceived behavior control. The usefulness and ease of use of green packaging, consumers' awareness of environmental responsibility and adequate publicity and education are the keys to enhance consumers' acceptance.
