laminated aluminum foil stand up zipper coffee bean bags with plastic coffee filters bag with zipper & hang hole

The aluminum foil compound pocket with the vent valve: It is a small package most perfect for the storage and sales of coffee beans. With the single vent valve, it can discharge the carbon dioxide generated during the storage process and impede the penetration of air into the bag. The clamp design of the product allows repeated uses, which effectively ensures the sealing and storage of coffee. The three-dimension style helps the product to stand erect without falling down. The aluminized brown paper clamp strip endows the bag with strong oxygen separation, shielding, anti-damp, anti-sun, and anti-stabbing performance.
