The vacuum packaging machine seals products in a low-oxygen environment by removing air from the packaging bag. This process helps reduce oxidation, preserve food quality, and extend shelf life. Foodline has developed a range of vacuum packaging equipment suitable for meat, seafood, nuts, snacks, vegetables, and other food products.
Foodline offers various types of vacuum packing equipment. Each type operates differently and is suited to specific applications.
1. Chamber Vacuum Packaging Machines
Working Principle: Fixed Chamber Batch Packaging
The chamber vacuum packing machine utilize a fixed vacuum chamber for sealing. Operators place products into pre-made vacuum bags and position them inside the chamber. Once the lid is closed, the machine automatically performs vacuuming, heat sealing, and pressure release. Afterward, the operator removes the finished package and begins the next cycle.
Key Features:
Available in single-chamber and double-chamber models.
Does not require a film-forming system or conveyor belt.
Simple operation with consistent vacuum sealing performance.
Suitable for meat, seafood, vegetables, and small-to-medium-scale production.
Working Principle: Automatic Bag and Cavity Forming
The thermoforming vacuum packaging machine uses a film roll instead of pre-made bags. The machine heats and stretches the bottom film to form the packaging cavity. After the product is loaded, the machine automatically completes vacuuming, top-film sealing, cutting, and package separation.
Key Features:
Creates packages with a clean and attractive appearance.
Supports close-fitting packaging for better product presentation.
Suitable for high-volume production.
Commonly used for meat products, snacks, seafood, and medical products.
Working Principle: Continuous Pre-made Bag Sealing
The continuous vacuum packing machine uses a conveyor belt to move vacuum bags through the packaging area. During the rolling process, the machine completes vacuuming, heat sealing, cooling, and package output automatically.
Key Features:
Works with ready-made vacuum bags.
Easy product changeover with different package sizes.
Suitable for multiple products and different production volumes.
A good choice for factories that need flexible packaging.
Working Principle: Vacuuming + Nitrogen Replacement
The vacuum nitrogen flushing packaging machine combines vacuum extraction and nitrogen filling. It removes air from the package fills high-purity nitrogen to replace remaining oxygen, and completes heat sealing.
Key Features:
Reduces oxidation and helps protect product freshness.
Keeps fragile products in better shape during storage.
Prevents crushing of light and crispy foods.
Suitable for puffed snacks, tea, nuts, dry foods, and other delicate products.
No. Fresh mushrooms, raw onions, garlic, some cheeses, and fresh fruits or vegetables with high respiration are not suitable for vacuum packing. In an oxygen-deprived environment, they may harbor harmful bacteria.
2. How long is the shelf life of vacuum-packaged food?
It depends on the food.
Dry goods: M months at room temperature
Fresh meat: 1 to 2 weeks in the fridge (normally 3 to 5 days)
Frozen meat: Up to 1 to 2 years with no freezer burn
3. Does vacuum packaging kill bacteria?
No. It only removes air and slows bacterial growth. To ensure food safety, it must be combined with measures such as refrigeration or heat treatment.
