in addition to valves, bosch packaging technology has developed other systems that protect especially sensitive products such as coffee. inertgas flushing makes it possible for vacuum packaging to have a residual oxygen level of less than one percent, and for soft bags to be filled and then fitted with valves. this means that oxygen can&rsquot harm the product from the outside or the inside and the aroma that everybody looks forward to can emerge intact when the bag is opened. that way, it is ensured everyone can start each and every day with the wonderful aroma of coffee.
