A review published in the journal Environmental Health Perspectives looked at the migration of hazardous chemicals from food packaging into the food itself.

BPA is just one of many known or suspected endocrine disruptors commonly found in food packaging that can migrate into food and drink. Furthermore, endocrine disruptors from plastics are far from the only class of potentially harmful chemicals that can leach into food or drink from food packaging; depending on factors including temperature, storage time, and physicochemical properties, a wide variety of compounds—including components of coatings and films, adhesives and glues, and inks and pigments—can migrate from packaging materials.

This review summarizes the challenge of food packaging, and how some manufacturers are trying to address it.
