A reclosable package that includes a pouch of flexible material that includes a reclosable closure secured to the flexible material adjacent an opening to releasably retain the opening of the pouch in a closed state. The closure includes fastenable closure strips that extend along opposite sides of the opening and that are releasably fastenable in multiple relative positions spaced along each of two perpendicular directions. The closure and flexible material of the pouch are configured to provide a maximum stiffness, in resistance to bending about a pouch axis extending along the pouch perpendicular to the closure strips, as determined at a point along the closure with the closure strips fastened, that is more than 10 times the maximum stiffness, in resistance to bending about the pouch axis, of one of the closure strips as secured to the flexible material, as determined at the point along the closure with the closure strips unfastened.

1. A reclosable package comprising a pouch of flexible material defining an interior volume and an opening providing access to the interior volume; anda reclosable closure secured to the flexible material adjacent the opening and operable to releasably retain the opening of the pouch in a closed state after partial removal of contents from the interior volume, the closure comprising fastenable closure strips extending along at least portions of opposite sides of the opening;wherein the closure strips are releasably fastenable in multiple relative positions spaced along each of two perpendicular directions;wherein the closure and flexible material of the pouch are configured to provide a maximum stiffness, in resistance to bending about a pouch axis extending along the pouch perpendicular to the closure strips, as determined at a point along the closure with the closure strips fastened, that is at least 10 times the maximum stiffness, in resistance to bending about the pouch axis, of one of the closure strips as secured to the flexible material, as determined at the point along the closure with the closure strips unfastened; andwherein the closure extends from a first side edge region of the pouch to a second side edge region of the pouch along a top region of the pouch such that, when the closure strips are fastened, the closure inhibits the flexible material of the pouch adjacent the closure from becoming deformed. 2. The reclosable package of claim 1, wherein the closure strips carry compatible arrays of discrete fastening projections, the arrays featuring multiple rows and multiple columns of fastening projections that are interengageable in multiple relative positions along each row and along each column. 3. The reclosable package of claim 2, wherein each projection is in the form of a hook having a head that extends to a reentrant tip to form a crook. 4. The reclosable package of claim 3, wherein the hooks of each strip extend from a flexible, unitary base, the base and hooks of each strip forming a single, contiguous mass of resin. 5. The reclosable package of claim 3, wherein the head of each hook overhangs the base on a side opposite the tip of the head. 6. The reclosable package of claim 1, wherein the pouch defines a flexible face surface carrying graphics that overlie the closure. 7. The reclosable package of claim 1, wherein an edge region of the pouch adjacent the closure defines an aperture through the flexible material, on a side of the closure opposite the interior volume, by which aperture the pouch is supportable in a hanging position when filled, the closure stiffening an upper portion of the package when hung from the aperture. 8. The reclosable package of claim 1, wherein the pouch has a gusseted end spaced from the opening, such that the pouch is configured to be self-supporting in an upright position on the gusseted end when filled. 9. The reclosable package of claim 8, wherein the opening is disposed at an upper end region of the pouch in its upright position. 10. The reclosable package of claim 1, wherein the pouch comprises a front face panel and a rear face panel that are sealed together along the side edge regions. 11. The reclosable package of claim 1, wherein the pouch of flexible material comprises a front face panel that defines the opening, and one of the closure strips is attached to the front face panel above the opening and another of the closure strips is attached to the front face panel below the opening. 12. The reclosable package of claim 1, wherein the closure comprises a base having a thinned tear region that connects a first of the closure strips to a second of the closure strips. 13. The reclosable package of claim 12, wherein the thinned tear region is configured to be manually torn so that the first and second closure strips can be separated from one another. 14. The reclosable package of claim 1, wherein the closure and flexible material of the pouch are configured to provide a maximum stiffness, in resistance to bending about the pouch axis, as determined at a point along the closure with the closure strips fastened, that is at least 15 times the maximum stiffness, in resistance to bending about the pouch axis, of one of the closure strips as secured to the flexible material, as determined at the point along the closure with the closure strips unfastened. 15. The reclosable package of claim 14, wherein the closure and flexible material of the pouch are configured to provide a maximum stiffness, in resistance to bending about the pouch axis, as determined at a point along the closure with the closure strips fastened, that is at least 20 times the maximum stiffness, in resistance to bending about the pouch axis, of one of the closure strips as secured to the flexible material, as determined at the point along the closure with the closure strips unfastened. 16. The reclosable package of claim 1, wherein the closure and flexible material of the pouch are configured to provide a maximum stiffness, in resistance to bending about the pouch axis, as determined at a point along the closure with the closure strips fastened, that is 10-30 times the maximum stiffness, in resistance to bending about the pouch axis, of one of the closure strips as secured to the flexible material, as determined at the point along the closure with the closure strips unfastened. 17. The reclosable package of claim 1, wherein the closure and flexible material of the pouch are configured to provide a maximum stiffness, in resistance to bending about the pouch axis, as determined at a point along the closure with the closure strips fastened, that is 15-25 times the maximum stiffness, in resistance to bending about the pouch axis, of one of the closure strips as secured to the flexible material, as determined at the point along the closure with the closure strips unfastened.
