The 1 pound Kraft valve seal bag can be used to package ground or whole coffee beans, loose-leaf teas and more. The block bottom allows them to stand up even before they are filled, and the four corner seal adds durability for shipping and handling. The one way degassing valve is essential for coffee bags due to the carbon dioxide that is released from freshly roasted coffee beans. The valve keeps your coffee fresh and prevents the bags from bursting.
