to WP4. 2.3 for reference purposes. Definitions: Migration modelling is now well established for many mono-layer plastics. However, the scientific basis for multi-layer migration modelling is not sufficiently developed. Migration of a chemical from a ML-FCM is controlled by the diffusion within the ML-FCM followed by the transfer into the food, F, and diffusion within this food. A model to describe this should take into account: Sub-task 2. Mathematical solution of the model Sub-task 3. Setup of the model for plastic multi-layer materials Sub-task 4. Implementation of particular layers: paper/board, coatings, adhesives, printing inks. Sub-task 5. Demonstration of workability of the full migration model Sub-task 6. Compiling a comprehensive data set of diffusion and partition constants (D and K)
