All food packaging including plastic, cardboard, metal, glass and ceramics can harbour potentially toxic chemicals that migrate into food.
A recent editorial in the journal Environmental Health Perspectives reviews current challenges to reducing chemical migration from food packaging into food contents.

A number of these chemicals have been linked to important health effects, with bisphenyl A (BPA) one of the best-known examples. But even BPA-free packaging may simply use problematic alternatives.
Currently no packaging is perfect, but consumer demand for chemical-free packaging is growing and the food industry, research institutions and non-government groups are making some progress. Read the full article here.
