Shuliy modified atmosphere packaging machine (MAP machine) is an advanced food packaging solution that extends shelf life by replacing air inside the package with protective gases such as nitrogen (N2), or a mixture of gases(N2+CO2+O2, etc). This technology effectively inhibits bacterial growth, prevents oxidation, and maintains the natural color, flavor, and nutritional value of fresh foods.
Our vertical MAP tray sealer offers both airflow and vacuum-type operation modes to meet medium-to large-scale food processing operations. With a production capacity of 300-700 packages per hour, this machine strikes the perfect balance between throughput and precision.
Compared to conventional packaging methods, our MAP packaging machine can achieve 3-5 times longer shelf life, making it ideal for meat processing, seafood packaging, ready meals, and fresh produce businesses.

FAQ of Fruit MAP Modified Atmosphere Packaging Machine
What is the difference between vertical and desktop MAP machines?
Vertical MAP machines offer both airflow and vacuum operation modes, support mixed gases (N2+CO2+O2), and handle 300-600 packages per hour.
Desktop MAP machines only offer airflow mode, support nitrogen only, and process 100-300 packages per hour.
Can the vertical MAP food tray sealing machine use mixed gases?
Yes, the vertical MAP machine supports custom gas mixtures including nitrogen (N2), carbon dioxide (CO2), and oxygen (O2).
When should I use vacuum mode vs airflow mode?
Use vacuum mode for diced products, small pieces, irregular shapes, items with cavities, and when using mixed gases or skin packaging.
Use airflow mode for whole meat cuts, steaks, fillets, and flat products where speed is prioritized and nitrogen-only flushing is sufficient.
Is the vertical MAP tray sealer machine suitable for skin packaging?
Yes, the vertical MAP modified atmosphere packaging machine supports skin packaging when operating in vacuum mode.
Can I use MAP machine for fruits and vegetables?
Yes, MAP machines can be used for many fruits and vegetables.
What maintenance does the vertical MAP machine require?
Regular maintenance includes daily cleaning of chambers and sealing bars, weekly inspection of vacuum pump oil level and gasket condition, and monthly checks of gas lines and electrical connections.
The vacuum pump oil should be changed every 500 operating hours or 3 months. Annual professional inspection is recommended for optimal performance.
