✦ Synopsis

The transfer of a contaminant into solid food from a bottle by radial diffusion is considered, when this bottle consists of two polymer layers, one being a recycled polymer, and the other, a virgin polymer. The virgin polymer layer located between the recycled polymer layer and the food plays the role of a functional barrier. The effect of the relative thicknesses of the recycled and the virgin layers on the contaminant transfer is especially studied. The results are expressed in terms of profiles of the concentration of a contaminant developed through the bottle and the food and of the kinetics of a contaminant transferred into the food. The contaminant concentrationtime histories are also drawn at various places in the food. Dimensionless parameters are used to obtain results to use in various typical cases.
