Products that naturally emit gases, such as coffee beans and animal feed, can cause the packaging container to swell, especially when packaged in composite bags. The gases generated by the continued fermentation of the product not only change the packaging shape but can even cause it to burst.
The solution is to weld a one-way degassing valve onto the bag. This allows excess gas to escape smoothly, ensures content quality, and eliminates bulging or bursting risks. The valve prevents external oxygen from entering and causing product oxidation and deterioration. Degassing valves with filters filter the powder inside the bag, preventing spillage and contamination.
