Abstract

A reclosable package having a two-dimensional zipper attachment on the exterior of one wall. The zipper comprises a pair of zipper strips that have straight central sections and end sections that curve or bend, diverging from the straight central section.

A flap portion of the wall, with one of the zipper strips attached to its periphery, can then be folded back to provide a wide opening for accessing the package contents.
