MIGRATION

In food packaging, migration usually refers to the migration of chemicals, taint, or odors, from the packaging materials or processes, to the food product. Migration can potentially affect the taste or odor of a food product, and doesn’t necessarily have to involve direct food contact. Preventing migration in food packaging involves controlling not only the materials (inks, coatings, papers, fountain solutions, glues, Etc.), but also the processes used to produce the package, and the environment within which the package was stored, handled, and transported. In many cases, a given material like ink, coating, or paper, may have no migration issues under one set of environmental conditions, but will under another set of conditions.
