ABSTRACT:
A flexible, pleated container has a wall structure comprising a barrier component which renders the container wall structure impervious to oxygen and water vapor. The barrier component is substantially uniformly effective throughout the entire wall structure. In a preferred embodiment of the invention, the thickness of the wall structure gradually decreases towards the outer extremities of the pleats with the thinnest wall portion located at the apexes of the pleats. The barrier component, however, is maintained at substantially uniform thickness throughout the wall structure.
