Aiming at the problem that the current method of packaging evaluation is scattered and the evaluation indicators are not comprehensive, the work aims to establish a set of packaging evaluation methods that can systematically reflect the whole process of consumer's emotional interaction to effectively obtain evaluation feedback. Through the investigation method and physiological measurement instrument measurement method, the consumer's subjective evaluation and measurement data on the packaging samples were obtained, including the data on the satisfaction of each indicator. The experimental results showed that, in the packaging design, the smooth shape, medium and high saturation color and appropriate graphic ratio could get consumer's attention in the process of use. In addition, three levels of evaluation system based on emotional interaction were established, and the weights of the first-level indicators (instinct layer, behavior layer, reflection layer) calculated to be 0.25∶0.35∶0.4 and the weight distribution of the second and third-level indicators were obtained. The evaluation system reflects the whole cycle of user's emotional interaction, which provides an evaluation method for the comparison of package design schemes. Moreover, its feasibility is verified and analyzed through cases.
