MAP (Modified Atmosphere Packaging)
Category: Food Trade
Also searched as: Modified atmosphere packaging
Definition (plain English)
Packaging that changes the gas mix around food, often reducing oxygen or adding carbon dioxide/nitrogen to slow spoilage or quality loss.
Why it matters commercially
MAP can extend shelf life, but only when film, seal, gas mix, storage temperature, label claims, and destination-market food rules all work together.
Example
A chilled ready-meal importer required gas-mix evidence and seal checks before accepting the supplier shelf-life claim for a 21-day delivery window.
Common mistake
Treating MAP as a generic shelf-life fix without validating product testing, cold-chain assumptions, labeling, and regulator or customer requirements.
