Diffusion and Permeability
The measurement of diffusion and permeation of vapours and liquids, including moisture, through packaging films and real packaging devices is important for the development of both pharmaceutical, catalyst, adsorbent and food packaging solutions. Typical requirements of these packaging systems are that the ingress and/or loss of moisture over long storage periods must be kept to a minimum in order to prolong the shelf life of the product.
