Extended Abstract This work aims to prepare and characterize novel nanocomposite materials based on low density polyethylene (LDPE) and titanium dioxide (TiO2) nanostructure for food packaging applications. The fabricated nanocomposites films were examined by X-ray diffraction pattern (XRD) and mechanical properties. The XRD results confirmed that the formation of LDPE nanocomposites films containing different concentrations of TiO2 nanostructure. The mechanical properties of the prepared LDPE/TiO2 nanocomposites were investigated. Moreover, the thermal properties of the prepared films displayed that the good enhancement of the thermal stability of the prepared film after addition of TiO2 nanostructure. Furthermore, the permeability of oxygen transmission rate (GTR) and water vapor transmission rate (WVTR) of the prepared LDPE nanocomposites were evaluated. Moreover, the antimicrobial activity of the prepared films against gram positive (Staphylococcus aureus) bacteria and gram negative (Pseudomonas aeruginosa) bacteria were investigated.
