In this work, natural plasticizers-modified polypropylenes intended for food active packaging were developed. Sunflower oil, olive oil, and soy lecithin, without any known harmful effects or toxicity, were employed as natural plasticizers, also implementing the attractiveness of using synthetic plastics on active packaging developments. Their incorporation during the extrusion of polypropylene was tried as a means to obtain polymers with improved diffusion paths, allowing differences in antioxidant release rates for active packaging materials. Thermal and rheological characterization of the films showed that blending natural plasticizers do not significantly modify their thermal properties; however, small variations of viscoelastic properties were observed. Furthermore, the resulting release of tocopherol was highly dependent on the polymer formulation. Furthermore, it was clearly time-controlled by using those natural plasticizers, especially olive oil. Antioxidant activity results also showed that packaged foods are protected against oxidative degradation over time, resulting from the improved release of the antioxidants.
