Migration Testing

SHARE
Migration testing evaluates whether chemical substances from materials—such as plastics, coatings, rubber, or packaging—transfer into food, liquids, or skin-contact environments during real use. It helps ensure products are safe, compliant, and free from harmful levels of additives, metals, or contaminants. Migration testing is essential for industries like food packaging, toys, consumer goods, pharmaceuticals, and polymers to verify material stability, improve quality, and meet global safety standards.

Migration testing determines how chemical substances move from a material into food, liquids, or skin-contact environments when exposed to real-world conditions like heat, storage, acidity, or moisture. It helps identify whether additives, metals, plasticizers, or contaminants remain within safe limits and ensures that products made from plastics, rubber, coatings, and packaging do not release harmful substances.

This testing is essential for industries that work with food packaging, toys, utensils, consumer products, and pharmaceutical materials. By understanding material behavior, manufacturers can improve product quality, meet regulatory requirements, and ensure long-term safety for users. Migration testing ultimately supports cleaner materials, stronger compliance, and safer everyday products.
