High-Efficiency Vacuum Packaging Machines for Food Preservation

A vacuum pack with gas flush is a highly effective packaging solution that combines the benefits of vacuum packaging with the addition of a protective gas mixture. This technique is widely used in the food industry to extend the shelf - life of products while maintaining their freshness, flavor, and quality. The process begins with placing the food product inside a packaging material, such as a bag or tray. Then, a vacuum is applied to remove the air from the package. This step is crucial as it reduces the oxygen levels inside the package, inhibiting the growth of aerobic bacteria, mold, and other spoilage - causing organisms. After the vacuum is created, a carefully selected gas mixture, typically consisting of gases like nitrogen, carbon dioxide, or a combination of both, is flushed into the package. Nitrogen, being an inert gas, helps to displace the remaining oxygen and provides a cushioning effect, preventing the product from being crushed during handling and transportation. Carbon dioxide has antibacterial and antifungal properties, further enhancing the preservation of the food. The ratio of the gas mixture can be adjusted based on the specific requirements of the food product. For example, fresh meats may require a higher proportion of carbon dioxide to
