The MAP (Modified Atmosphere Packaging) Gas Flushing Thermoforming Machine is a specialized piece of equipment used in the food packaging industry to create hermetically sealed packages with modified atmosphere conditions. This type of machine combines the processes of thermoforming and gas flushing to package food products in a way that helps extend their shelf life and maintain quality.
Here's an overview of how this machine works and its key components:
1. Thermoforming Process:
- The machine forms plastic film into the desired package shape using heat and vacuum or pressure.
- This creates trays, cups, or other containers for the product.
2. Product Loading:
- The formed packages move along a conveyor belt to where the product is loaded.
- Depending on the design, this could be automated or manual.
3. Gas Flushing:
- After loading, the packages pass through a gas flushing station.
- Inert gases like nitrogen, carbon dioxide, or oxygen blends are injected to replace the air inside the package.
- This process removes oxygen and other gases that can contribute to spoilage.
4. Sealing:
- A lid film is applied over the formed packages.
- The film is sealed to the formed base, creating an airtight seal.
- Some machines use a peelable lidding film for easy opening by consumers.
5. Modified Atmosphere Packaging (MAP):
- The sealed packages contain a specific gas mixture that slows down spoilage processes.
- Common gas ratios include 80% nitrogen, 15% carbon dioxide, and 5% oxygen.
6. Cutting/Trimming:
- Excess film is trimmed away, creating clean, finished packages.
Key features of MAP Gas Flushing Thermoforming Machines:
- High-speed production capabilities
- Precise control over gas flushing and sealing processes
- Ability to handle various film types and thicknesses
- Customizable tray designs
- Integration with labeling and coding systems
- Hygienic design for food safety compliance
Benefits of using MAP Gas Flushing Thermoforming Machines:
- Extended product shelf life
- Reduced food waste
- Improved product appearance and quality
- Increased flexibility in packaging options
- Enhanced brand image
These machines are commonly used in the meat, poultry, seafood, produce, and prepared foods industries. They help processors meet consumer demands for fresh, high-quality products while extending the time products can remain on store shelves.
This equipment is our company according to many years of R&D and production of automatic continuous
Thermoforming Packaging Machine, combined with modified atmosphere function of the MAP machine, independently developed a thermoforming machine for flexible or rigid film with modified atmosphere (MAP) and vacuum options. The machine's forming, vacuum, gas filling, printing production date, cutting and other functions are fully synchronized, with smooth process and stable performance. This equipment solves the limitation that the thermoforming packaging machine can only stretch flexible film or rigid film. It truly realizes the multi-purpose of one machine and meets the packaging needs of our customers.
