How to Use This Calculator
  1. Enter target O₂ and CO₂ percentages for your modified atmosphere.
  2. Set package volume in mL, product weight in grams, storage temperature, and base shelf life without MAP.
  3. The calculator shows N₂ balance, gas-to-product ratio, shelf life extension factor, estimated MAP shelf life, CO₂ absorbed, package collapse risk, and O₂ depletion time.
  4. Select gas mix and packaging material with appropriate barrier properties based on the O₂ and CO₂ targets.
  5. Monitor CO₂ absorption collapse risk—if above 30%, increase N₂ or reduce CO₂ in the mix.
