A new experimental procedure for incorporation of model contaminants in polymers was developed as part of a general scheme for testing the efficiency of functional barriers in food packaging. The aim was to progressively pollute polymers in a controlled fashion up to a high level in the range of 1000 ppm and use them as input for the core layer of a tri-layer package, in order to monitor migration phenomena difficult to study in real conditions. To this end, a contamination recipe was initially formulated by a set of selected surrogates. The experimental procedure developed, led to satisfactory results as far as homogeneity and final concentration in the polymer s concerned. High temperature data were also used in order to evaluate the efficiency of typical thermoforming processes in reducing possible volatile and non-volatile substances from recycled polymeric materials.
