Why is an eight sided sealed coffee bag with a valve suitable for storing coffee beans?

Design of one-way exhaust valve

Coffee beans will release carbon dioxide during the roasting process. If these gases cannot be discharged in a closed environment, it will cause an increase in internal pressure, which may damage the structure of the bag or affect the quality of the coffee beans. This valve allows the coffee beans inside the bag to release carbon dioxide gas. Meanwhile, this design prevents external air and moisture from entering the bag, ensuring a stable storage environment for coffee beans, thereby slowing down their oxidation process and maintaining their freshness and flavor.

Eight sided sealing structure

The eight sided sealing coffee bag has eight edges at the sealing point, which is more complex than ordinary sealing and can provide a tighter sealing, effectively preventing air, moisture, and light from entering the bag. This helps to maintain a low oxygen environment for coffee beans and prevent them from quickly spoiling due to their reaction with oxygen. Moreover, the design structure of the octagonal seal usually adopts heat sealing technology, which not only ensures the firmness of the seal, but also allows the bag to withstand greater pressure at the seal, avoiding the bag from bursting due to the gas released by the coffee beans.

Food grade materials

These bags are usually made of food grade materials, such as polyethylene (PE), polypropylene (PP), etc., which are free of harmful substances and can safely come into contact with food without causing pollution to coffee beans, ensuring the quality and safety of coffee beans.

Moisture and Light Protection

The valve design is usually located at the top of the bag, which can protect other parts of the bag from moisture and light, which is crucial for preventing coffee beans from getting damp and maintaining their color and aroma. In addition, the outer layer material of octagonal sealed coffee bags usually has good shading performance to prevent coffee beans from spoiling due to the influence of light.

Easy to identify and track

The shape and structure of the octagonal sealed coffee bag provide enough space on the surface to print information about the coffee beans, such as variety, baking date, shelf life, etc. This helps consumers understand the relevant information of the product and ensure that they purchase fresh and high-quality coffee beans.

Adaptability

This type of coffee bag is suitable for storing coffee beans of all sizes, whether it is small or large packaging, suitable octagonal sealed coffee bags can be found. Moreover, the appearance design of the octagonal sealed coffee bag is simple and generous, which is conducive to improving the overall aesthetics of the product packaging.
