Poultry MAP tray sealer | Modified Atmosphere Packaging Machine
A specialized MAP machine designed for fresh poultry. It replaces air with a gas mixture to extend shelf life, maintain freshness, and enhance product appearance—ideal for supermarkets, meat processors, and cold-chain logistics.
Function of Modified Atmosphere Packaging Machine:
Feeding (By manual or machine) – Modified Atmosphere Packaging (Automatic vacuuming and inflation) – Sealing
Feature of modified atmosphere packing machine:
1.Modified Atmosphere Packaging (MAP)
Uses mixed gases to inhibit the growth of bacteria and mold, and slows down the oxidation process to preserve freshness.
2.Shelf Life Extension
Significantly extends the shelf life of food under ambient or refrigerated conditions compared to regular packaging.
3.Appearance & Flavor Protection
Maintains the original color, texture, and taste of products—especially suitable for fresh meat, cooked foods, and ready-to-eat items.
4.Automated Sealing & Gas Flushing
Performs vacuuming, gas injection, and sealing automatically, improving packaging efficiency and consistency.
5.Flexible Gas Mixing Control
Allows adjustment of gas ratios to match the specific preservation needs of different types of food, ensuring optimal packaging results.
Why can modified atmosphere packaging preserve freshness?
1.Oxygen/O₂–Causes food spoilage, such as rancidity of fats, ripening and aging of fruits and vegetables, aging of baked foods, increase in microorganisms, etc. Fresh meat requires high levels of oxygen to maintain its bright red color, and fruit and vegetable packaging requires low levels of oxygen.
2. Carbon dioxide/CO₂–Can inhibit the growth of microorganisms, slow down respiration, easily soluble in water, and soluble in fat.
3. Nitrogen/N₂–Colorless and odorless inert gas, mainly used as filling gas to prevent packaging collapse.
4. The modified atmosphere packaging machine can also be used without filling any gas and has a single sealing function.
