Modeling of Mass Transfers between Food Simulants and Treated Plasticized PVC

摘要

PC is often used in food packaging and blood bags. This study concerns mass transfers between plasticized PVC, having been subjectedto a treatment, and liquid food or food simulants. The treatment reduces the diffusion of the plasticizer and the influence of some factors of this processing are investigated. A methematical model, able to simulate these mass transfers and to quantify the treatment parameters, is proposed.
