Abstract: Packaging assembly for the transport of coffee in the form of roasted beans, comprising: at least one impermeable bag, impermeable at least to oxygen and water vapour; said at least one impermeable bag being flexible and sealable in a watertight manner to prevent the introduction of fluids or gases; at least one unidirectional valve sealingly applied to said at least one impermeable bag which only allows gas to escape from the impermeable bag preventing the entry of gas into the impermeable bag, wherein said at least one unidirectional valve makes it possible to achieve an over-pressure inside the impermeable bag variable from 3 to 60 mbar.
