Due to the direct use of antibacterial agents, which can affect the appearance and quality of plastic products, coupled with unstable molding cycles, uneven dispersion of antibacterial agents, and significant pollution to the production environment, as well as difficulties in operation, the antibacterial effect is reduced, resulting in higher processing costs for antibacterial plastic production. Therefore, this method has fallen behind.

　　At present, the most commonly used plastic product processing method internationally is to produce antibacterial plastic products by adding antibacterial masterbatch. Antibacterial masterbatch is a granular concentrate made by mixing plastic and antibacterial agent carrier, with a high content of antibacterial agent (mass fraction: 10% -50%). When molding antibacterial products, only 1% -3% antibacterial masterbatch needs to be added to the plastic.

　　Through antibacterial masterbatch technology, not only is the dispersion effect of antibacterial agents greatly improved, but a large amount of blending and granulation work is also eliminated. The operation is simple, the molding cycle is stable, the production efficiency is improved, and the environment is not polluted at all. The product quality is guaranteed, so it has the most development potential in the antibacterial plastic products market.

　　From the application of antibacterial masterbatch, the formula and application of antibacterial materials are closely related to the processing and use of antibacterial materials. With the deepening of research and development, the formula of antibacterial materials will continue to enrich, new antibacterial masterbatch will continue to increase, and the application fields of antibacterial materials will also continue to expand.
