Oxygen scavenging films in food packaging

Eating safe and healthy food is a rising consumer awareness. Oxygen-sensitive foods can now be better protected using oxygen scavenging films, an emerging technology that extends the shelf life and maintains the quality and freshness of food products. The use of oxygen-absorbing materials in packaging is a current trend in active packaging, especially in food packaging. Some oxygen scavenging films have shown excellent oxygen absorbance and become commercial successes. Here, we review oxygen scavenging films used in food packaging, such as novel natural oxygen scavenging agents and active barrier films.
