Modified Atmosphere Packaging (MAP)
Remove or reduce oxygen, replace with nitrogen and/or CO2
- Minimize oxidation
- absorbs gases like ethylene
Active Packaging
Packaging that performs some desired fxn other than providing a barrier to the external enviro
Ex. the little pouches that say “do not eat” in packages

Edible coatings
Natural waxes, polysaccharides, corn gluten, whey protein
intelligent packaging
