Modified atmosphere packaging (MAP) of commodity
refers to the technique of sealing actively respiring produce
in polymeric film packages to modify the O
2
and CO
2
levels within the package atmosphere. It is often desirable
to generate an atmosphere low in O
2
and/or high in CO
2
to
influence the metabolism of the product being packaged
and the activity of decay-causing organisms to increase
storability and/or shelf life [
