Synthesis of LDPE/Nano TiO2 Nanocomposite for Packaging Applications %K Nanocomposite %K TiO2 Nanoparticle %K Packaging %K Permeability %R %X Improving barrier properties through the use of nanocomposites is an important area of research, especially for the food packaging industry. In this work, Titanium dioxide (TiO2 )/Low density Poly Ethylene (LDPE) nanocomposites were synthesized as the oxygen barrier layers through the co-extrusion process. The Oxygen permeability of the nanocomposite with 4% of TiO2 decreased for about 16% compared to the pristine LDPE. Furthermore, the rancidity of almonds in the packaging which is made of the former is about 78% less than the latter. Therefore, from the data obtained from the permeation, mechanical and degradation experiments, it can be concluded that these nanocomposites provide promising applications as O2-barrier and antidegradation agents in food packaging. %U https://www.ijnnonline.net/article_3901_efe63705b6485f663fb2681e54302d10.pdf
