A reclosable zipper (10) is provided that includes a female portion (12 ) having a first base (16) that defines a continuous groove (22), and a male portion (14) that includes a second base (26) and a male nib (28). The male rib extends outwardly from the second base for insertion into the continuous groove and is locked therein when the male and female portions are pressed together. A protective flange (32) extends outwardly from at least one of the first and second bases proximate the male rib or continuous groove of the reclosable zipper. When the zipper is employ ed in a packaging bag, such as a plastic bag (44), the protective flange deflects a granular or powdery packaged material away from the male rib and continuous groove, which inhibits clogging of these features and allows the zipper to be closed without interference.
