High-barrier MAP packaging film, suitable for tray sealing / MAP machines, preservative film for cooked food & marinated snacks
Product Description: MAP Packaging Film (气调膜)
1. Working Principle
Modified Atmosphere Packaging (MAP) film replaces the air inside the package with a mixed gas (such as CO₂, N₂, O₂) to inhibit bacterial growth, slow down oxidation and extend the shelf life of food.
Our high-barrier MAP film effectively locks in the gas mixture and prevents external air from entering, maintaining stable gas composition inside the package.
2. Product Functions

5. Differences Between MAP Film and Ordinary Sealing Film
- Barrier performance:
MAP film has extremely high oxygen and moisture barrier; ordinary sealing film has low barrier and cannot lock gas.
- Fresh-keeping effect:
MAP film supports modified atmosphere packaging and greatly extends shelf life; ordinary film only provides simple packaging.
- Application scope:
MAP film is specially designed for fresh food, meat, seafood and cooked food; ordinary film is only for general dry goods.
- Service life:
Food packaged with MAP film can be stored 3–10 times longer than with ordinary film.
