Development of antibacterial packaging films via sonication based onpolyethylene/ZnO nanoparticles

ZnO-nanoparticles have been used widely to achieve antimicrobial films in various applications including the foodindustry and packaging. ZnO (۰.۲۵ w%, ۰.۵ w%, ۰.۷۵ w%, ۱ w%, ۱.۵ w%, ۲ w%, ۳ w%, ۵ w%) was loaded intoLDPE along with tween ۸۰, a surfactant, and sonication to produce antibacterial film against Staphylococcus aureusas a Gram-positive test strain and Escherichia coli as a Gram-negative test strain. The incorporation of ZnOnanoparticlesinto LDPE films via sonication can enhance the antimicrobial properties of the material, providing asafer and more effective way to preserve food
