PVC is often used in food packaging and blood bags. This study concerns mass transfers between plasticized PVC, having been subjected to 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 mathematical model, able to simulate these mass transfers and to quantify the treatment parameters, is proposed.
