Abstract
A container having a thin film flexible container body includes upper and lower portions defining a predetermined longitudinal extent of the container so as to establish an interior region adapted to hold selected contents. The container body integrally includes, between the upper and lower portions, at least one rigid annular band so as to impart lateral strength and stability to the container. Preferably, the upper and lower portions of the container body are rigid (i.e., self-supporting) and are unitarily formed with the thin film flexible container body together with the annular rigid bands thereof.
