This article presents an analytical-numerical study of active food packaging is presented. Such packages have in their compositions materials through which oxygen may flow in both directions (from inside to external environment and vice versa), or just one (vaccum inside) and models describing this problem are usually formulated as coupled nonlinear partial differential equations. The main contribution of this paper is to show that a solution can be obtained from a well-known model using free software, following a combined analytical and numerical approach. The results obtained suggested that such an approach is valid and may lead to further developments in more accurate modeling. Our focus in this research is not to analyze what happens to the food contained in these packages, their practical uses, or their possible ecological and financial impacts on the food industry. We are focused on how to simulate these packages and collaborate with the research process on them.
