In the contemporary world, almost all foodstuffs on market are packed. Once the package material chosen, it is essentially to know if there is any interaction between food and the material in contact. The objective of this study was the supervising and control of materials in direct contact with cheeses in 2005 and 2008 and consisted in: identifying the conditions of contact between food and package, identifying the extraction conditions and verifying the global migration of components. The value of global migration of components from plastics tested before and after the contact with cheeses was not over the limits imposed by the legislation (10 mg/dm2 or 60 mg/kg). In conclusion, plastic materials in contact with foods are stable and respect the in force legislation.
