摘要：

Antibacterial polyethylene (PE) packaging films were prepared by combining granulation and casting with antibacterial agents sodium dehydroacetate (SD) and potassium sorbate (PS). The scanning electron microscopy (SEM) was used to characterize the structure of the films, and the effects of various additives on their physical, optical, microstructure, thermal stability, and antibacterial properties were investigated. The results show that when the SD: PS ratio is 2:1, the antibacterial film has higher tensile strength (14.71 MPa) than pure PE film. When the SD: PS ratio is 3:1, the water vapor transmission coefficient is the lowest, and The increase of SD concentration can result in good antibacterial activity against various microbes. The film has excellent physical and antibacterial properties, making it ideal for food packaging.
