A reclosable sack having a cross-bottom formed by folded-over side flaps has the confronting edges of the flaps spaced apart to define a slideway for a closure strip which is provided with a hole and is retained in the slideway by a cover sheet. When the closure strip is slid to a position where the hole is out of registry with emptying holes pierced in the material overlying and underlying the strip, the sack is substantially sealed.
