When attempting to create the best possible shelf life for a product, it's obviously desirable to design a packaging system that would yield the optimum modified atmospheres. But even with all the commercially-available polymeric films at your disposal, this task isn't as easy as it may first appear. For example, the optimum modified atmospheres for extending the shelf life of fresh produce span a wide range of carbon dioxide and oxygen compositions. Moreover, the atmospheres that can be established inside intact polymer packaging are limited by the narrow range of the permeability ratio of polymeric film.
One way of creating the desired atmosphere is to design ...
