The food packaging film has good antibacterial property.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a food packaging film with antibacterial function and a preparation method thereof. Background technique [0002] Food packaging film is a high polymer material used to wrap the surface of food, mainly to isolate the entry of decomposing microbial bacteria and foreign pollutants, to prevent food from deteriorating or to prolong the time of deteriorating. In recent years, food plastic packaging materials have gradually developed in the direction of high barrier, non-toxic, anti-aging, high strength, co-extrusion film, composite film, and environmental protection. Composite membrane. However, due to the trace air permeability and water permeability of bopp film and pp film itself, there is a great hidden danger for food that has been stored for a long time, and it is easy to be corroded by mold and microorganisms, and it is difficult to meet the antibacterial...
