In the food packaging industry, extending shelf life and maintaining quality are among the most important goals for manufacturers. Modified Atmosphere Packaging (MAP) is one of the most effective methods, increasing the longevity of food products and preventing early spoilage by carefully controlling the composition of gases in the package. Packen, a leading company in designing and producing tray sealer packaging machines, has utilized advanced technology and expertise to produce high-precision MAP machines. These machines are used for packaging food, medical equipment, and pet food.
This article will explore the advantages and precision of MAP implementation by Packen’s tray sealer machines and review key points from various stages of the process.

What is MAP in Food Packaging?
Modified Atmosphere Packaging (MAP) involves removing the air inside a package and replacing it with a mixture of gases such as carbon dioxide and nitrogen. The purpose of altering the atmosphere is to prevent oxidation and reduce microbial growth, which helps extend the product's shelf life and maintain its quality.The Role of Packen Tray Sealer Machines in Precise MAP Implementation
Packen tray sealer machines (Packen) enable optimal MAP execution through precise design and modern technology. These machines meet high standards in automation, mechanical, vacuum, and pneumatic systems, ensuring the accuracy and quality required for MAP implementation. Their precision is particularly important in laboratory environments, where devices undergo rigorous testing and feedback to ensure Packen machines consistently outperform others.Key Features of Packen Tray Sealer Machines for MAP Precision
- Advanced Automation Systems: Packen tray sealers feature advanced automation systems that automatically control and monitor every packaging stage. These systems allow precise adjustment of vacuum time, gas injection, and temperature.
- Accurate Mechanical Design Mechanically designed for precision, Packen machines ensure flawless sealing of packages. This includes specially crafted molds that prevent air leakage into the packages.
- High-Precision Vacuum and Pneumatic Systems The vacuum stage is the most critical step in MAP. Packen tray sealers utilize advanced vacuum systems that reliably remove all air from inside the package.
- Laboratory Feedback and Testing Packen machines undergo laboratory testing to collect precise feedback on their performance, ensuring each stage of the MAP process is error-free.
- Accurate Gas Purity Analysis Packen’s tray sealers use gas analyzers to assess the purity of injected gases like carbon dioxide and nitrogen. This ensures optimal packaging conditions, maximizing shelf life.
Impact of Precision in MAP on Product Shelf Life and Quality
The accuracy of MAP execution by Packen tray sealers significantly impacts product quality and shelf life. Each food product requires a specific protective gas composition, making precise adjustment of this composition essential.
Advantages of Packen Tray Sealer Machines in MAP Execution
- Extended Shelf Life Packen tray sealers can increase product shelf life by 3 to 10 times through accurate gas injection. This is especially beneficial for food manufacturers looking to extend product longevity.
- Preserving Nutritional Value and Quality By eliminating oxygen, which causes oxidation, MAP helps maintain a product's nutritional value and flavor.
- Preventing Quality Degradation During Transport and Storage Packen tray sealers provide precise packaging that prevents unwanted changes in the package, ensuring consistent product quality during long transport and storage periods. This is particularly important for export products.
