The work aims to explore the internal mechanism for the influence of food packaging materials on consumers' attention to processing and green purchase intention. A two-factor experimental design of 2 packaging materials (environmental protection and ordinary) × 2 types of food (utility food and hedonic food) was adopted. Under the simulated shelf shopping scene, Tobii Glasses2 eyewear eye tracker was used to collect the eye movement data (average fixation time, fixation count, hot spot map) of subjects when they browsed different types of food on the shelf. Then, combined with the behavioral data, the analysis was carried out. In terms of the average fixation time, the interaction between packaging materials and food types was significant, but the interaction in fixation count was not significant. The food packaged with environmental protection materials received more attention, and the subjects preferred to choose the hedonic food packaged with environmental protection materials. Packaging materials and food types jointly affect the consumers' visual perception effect and the processing process, and environmental protection packaging has a positive effect on young consumers' green purchase intention.
