In this review, the use of silver nanoparticles (AgNPs) in food packaging technologies was discussed from the perspective of regulation, methods, properties, migration, and challenges. Although AgNPs can improve physical, mechanical, and antibacterial properties of food packaging, a primary concern is focused on their possible toxicity in human health. More details about this figure will be discussed by Prof. Achmad Syafiluddin and his co-worker on page 1942-1956 in this issue.
