The modified atmosphere packaging machine is a type of packaging equipment. It achieves packaging by replacing the air inside the package with a precisely formulated gas mixture—such as nitrogen (N₂), oxygen (O₂), and carbon dioxide (CO₂). By utilizing specific gas ratios tailored to different food products, this technology effectively extends the product’s shelf life.
Taizy MAP packaging machine features a 304 stainless steel structure, incorporating advanced gas displacement technology and an intelligent control system. It achieves a packaging speed of 400 to 700 trays per hour. It is widely applicable for the tray packaging of various food products, including fresh meat, seafood, poultry, frozen foods, fruits, vegetables, and processed produce.

How does modified atmosphere packaging machine work?
The core principle of the MAP vacuum packaging machine is to displace the air within the packaging container using a mixture of gases.
Ordinary air accelerates food oxidation and bacterial proliferation, thereby leading to spoilage. By regulating the ratio of gases, modified atmosphere packaging effectively extends the shelf life of food products. Its typical workflow involves the following steps:
- Place the food-filled tray into the mold.
- Use a vacuum or airflow system to evacuate the air from the container.
- Inject nitrogen, oxygen, and carbon dioxide in accordance with a preset ratio.
- Complete the sealing process via a heat-sealing system.
Two types of MAP packaging machines
We offer two types of modified atmosphere packaging machines:
- Air-flow packaging machine
- Vacuum-type MAP packaging machine
Air-flow MAP tray packaging machine
The airflow-type modified atmosphere packaging machine primarily displaces the air within the packaging container using a high-speed airflow, and subsequently infuses a mixed preservation gas. Its parameters are as follows:
| Model | JR-M330S | JR-M380S | JR-M410 | JR-M450 |
|---|---|---|---|---|
| Max film roll Diameter | 330mm | 380mm | 410mm | 450mm |
| Max film width | 240mm | 240mm | 240mm | 240mm |
| Gas replacement Rate | ≥99% | ≥99% | ≥99% | ≥99% |
| Gas mixing Accuracy | ±2% | ±2% | ±2% | ±2% |
| Velocidad de envasado | 8s/cycle | 9s/cycle | 10s/cycle | 10s/cycle |
| Capacity (2 trays) | 500trays/h | 500trays/h | 500trays/h | 700trays/h |
| Capacity (4 trays) | 800trays/h | 800trays/h | 800trays/h | 800trays/h |
| Power supply | 220/380 V | 220/380 V | 220/380 V | 220/380 V |
| Working air pressure | 0.6–0.8MPa | 0.6–0.8MPa | 0.6–0.8MPa | 0.6–0.8MPa |
vacuum-type modified atmosphere packaging machine
The vacuum-type modified atmosphere packaging machine employs a process of first evacuating the air and then back-flushing with gas. The equipment utilizes a vacuum pump to extract the air from within the packaging container, and subsequently injects a preservation gas mixture in precise proportions. The detailed specifications for this packaging machine are listed below:
| Model | JR-M330S | JR-M380S | JR-M410 | JR-M450 |
|---|---|---|---|---|
| Max film roll Diameter | 330mm | 380mm | 410mm | 450mm |
| Max film width | 240mm | 240mm | 240mm | 240mm |
| Gas replacement Rate | ≥99% | ≥99% | ≥99% | ≥99% |
| Gas mixing Accuracy | ±2% | ±2% | ±2% | ±2% |
| Velocidad de envasado | 15s/cycle | 15s/cycle | 15s/cycle | 15s/cycle |
| Capacity (2 trays) | 300trays/h | 300trays/h | 300trays/h | 500trays/h |
| Capacity (4 trays) | 500trays/h | 500trays/h | 500trays/h | 500trays/h |

| Working air pressure | 0.6–0.8MPa | 0.6–0.8MPa | 0.6–0.8MPa | 0.6–0.8MPa |
Difference between MAP packaging machine & vacuum packing machine
In the food packaging industry, the modified atmosphere packaging machine and the vacuum packaging machine are two common methods for food preservation. Although both can extend the shelf life of food products, they differ significantly in their underlying principles and the types of products to which they are best suited.
| Comparison Item | Modified atmosphere packaging machine (MAP) | Vacuum packaging machine |
|---|---|---|
| Packaging principle | Replace air with mixed gases (N₂, CO₂, O₂) | Remove air to create a vacuum environment |
| Food appearance | Keeps the natural shape of food | Food may be compressed or deformed |
| Preservation method | Controls gas ratio to slow bacterial growth | Reduces oxygen to slow oxidation |
| Maintains color, freshness, and texture | Ideal for supermarket display | Mainly used for storage and transportation |
| Packaging effect | Controls the gas ratio to slow bacterial growth | Focuses on longer storage time |
