This has become of paramount importance due to the legislations set by the regulated markets. The technical capabilities have been growing rapidly, that can be exploited for analyzing product-package interactions. Different techniques, categorized according to the state of the diffusant (gas or liquid) in contact with a packaging material are emphasized in this review. Depending on the diffusant and on the analytical question under review, the different ways to study sorption and/or migration are presented and compared. Some examples have been suggested to reach the best possible choice consisting of a single technique or a combination of different approaches.
