Critical points responsible for contamination
Food contact: conformity assessment - Part 1

The migration of high-mass molecules (between 200 and 2,000 g · mol ^–1 ) of the "additive" type is only possible after prolonged contact (typically several hours to several days at room temperature) between the packaging and the food (figure 6 ). In the case of volatile molecules (low-molecular-weight additives, ink solvents or processing aids), contamination can occur with or without contact, after passing through...
