The process of the transfer of a contaminant through a package made of a recycled film in good contact with a virgin film playing the role of a functional barrier is studied. The two films being made of the same polymer, the contaminant diffuses within the two layers of polymer with the same constant diffusivity. Convective transfer of the contaminant takes place through the surface of the functional layer in contact with the food, while the other external surface is impermeable to it. The effect of the coefficient of mass transfer at the packaging‐food interface on the rate of transfer of the contaminant to the food is especially studied. Dimensionless numbers are used, making the results general.
