The effect of food simulants on properties and light barrier function of LDPE-nano TiO2 composite film has been investigated. LDPE-nano TiO2 composite films were prepared with 5.0wt% TiO2 content by melt-extrusion. To simulate food contact environment, according to KFDA standards and specifications for food utensils, containers and packages, food simulants were selected with deionized water, 50% ethanol, 4% acetic acid and n-heptane and composite films were immersed in each food simulant at 70oC, 30 min except n-heptane (25oC, 60 min). A variety of material properties, including crystallinity, chemical bonds, surface morphology, mechanical, oxygen barrier and optical properties, of LDPEnano TiO2 composite film were examined with and without the food simulants treatment. As a result, under regulated migration condition, LDPE-nano TiO2 composite showed extremely stable in all properties tested in the study in contact with food simulants indicating that TiO2 nanoparticles are physicochemically stable and quite compatible with LDPE. Results enable us to anticipate migration of TiO2 will probably not occur. To evaluate influence of migration of TiO2 on food stuffs, their color, pH and acidity were observed as well.
