Abstract: Nowadays, people pay more and more attention to the health of the home environment. The health function design of household appliances has become an important element in product design. How to improve the health performance of materials has become an important consideration for product designers. Plastic, as the material with the most proportion and the most contact with food in refrigerators, can enhance the antibacterial function of plastic parts and enhance the health competitiveness of products. By analyzing the characteristics of antibacterial agents, combining with the current molding technology of refrigerator plastic parts, the selection and molding technology of plastic antibacterial agents are optimized, the application of antibacterial plastics as health material in refrigerator was introduced.
