The 1 lb Kraft valve seal bag can be used to package ground or whole coffee beans, loose-leaf teas and more. The narrow width of the bags make them perfect for sampling. 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.
