The invention provides a base structure of a container. The base structure includes a support heel that defines any number of touch points for contact with a horizontal surface. The support heel includes inner and outer portions that merge with the container's corrugated support flute and sidewall, respectively. The base structure also includes a fin that forms the zipper pinch and extends transverse to and intersects corrugations of the corrugated support flute.
