Feasibility study for the development of a Multiparameter-Reference Material for food contact material testing and characterization

− This paper reports a feasibility study for the development of a Multiparameter-Reference Material (RM) to be employed for food contact material testing and characterization. Two test batches have been prepared starting from a film of Poly-Lactic Acid (PLA) and from the same film coated with a silver layer (Ag-PLA) and then they were submitted to optical, morphological, mechanical and chemical characterization. The final objective is to obtain a RM to be certified for chemical composition, to be accompanied by reference values for migration tests (also for evaluating nanoparticle release) and optical and mechanical properties.
