This question sits at the heart of food contact material (FCM) regulations worldwide and has become increasingly important as packaging structures grow more sophisticated and regulatory requirements continue to evolve. Understanding Migration in Food Packaging Plastic food packaging is far more than a simple polymer. Modern packaging materials often contain a combination of: Monomers Additives Stabilizers Processing aids Plasticizers Antioxidants Colorants and coatings These substances are used to improve performance, durability, appearance, and processing efficiency. However, under certain conditions, some of these substances may transfer from the packaging into food. This phenomenon is known as migration . Migration does not automatically im...
