What types of testing are involved in food packaging materials?

Packaging Material Hygiene and Safety Testing

• Total migration, heavy metals, potassium permanganate consumption, and decolorization test
•    Harmful metal elements (barium, cobalt, copper, iron, lithium, manganese, zinc, etc.)
•    Additives, auxiliaries, and migration levels of harmful substances (such as mineral oils, plasticizers, bisphenols, nonylphenols, etc.)
•    Organic Volatile Compounds and Residual Solvents (such as Formaldehyde, Acetaldehyde, Benzene-Based Solvents, etc.)

Microbial Testing of Packaging Materials
