Bosch has offered aroma protection valves for the economical packaging of degassed products like coffee since 1980. The use of over a billion valves world wide proves the excellent functionality. The “aromafin” valve technology has continually been improved and offers state-of-the-art technology. With aroma protection valves coffee can be packaged directly after the roasting process without interim storage. In the perfectly shaped package the aroma of fresh roasted coffee is preserved and stays as fresh as the first day. The valve is easily attached and processed securely to the inside or outside of the foil by valve applicators that are available for all standard machine models.
