Migration is the transfer of a substance between two media in contact, especially during the interaction between the container and its content. In packaging, the word has a precise meaning: a substance of the packaging can migrate into the product, or the other way round. A simple example: the smell of new fabric passing into the product. It is a serious matter for food, cosmetics and perfumes.

The best way to avoid migration is to pre-wrap the product concerned.
