All over the United States, all states have strict management and monitoring systems covering the field of food production, packaging and distribution to ensure the safety and hygiene of food contact materials and products. Among them, the US Food and Drug Administration ( FDA ) played a key role in this process, and its regulations on food contact safety regulations are very specific and complex. For materials and products that come into contact with food, the US FDA considers food packaging materials to be within the scope of food additive management. FDA's definition of food additives includes all substances that become food ingredients or affect the properties of food through direct or indirect addition or contact with food. Substances that migrate into food due to packaging, storage or other processing processes are indirect additives.

Food additives are detailed in Parts 174, 175, 176, 177, and 178 of Title 21 of the United States Code of Federal Regulations, Food, Drug, and Cosmetic (21.CFR.Part; 174.175.176.177.178).
