A zipper (10) having interlocking profiles (16, 20) wherein the male profile (16) has at least two male ribs (26, 30) bordering a male rib (28). The male profile (16) is engagable with a female profile (20), wherein the female profile (20) includes grooves (38, 48). The grooves (38, 48), attached to

A zipper (10) having interlocking profiles (16, 20) wherein the male profile (16) has at least two male ribs (26, 30) bordering a male rib (28). The male profile (16) is engagable with a female profile (20), wherein the female profile (20) includes grooves (38, 48). The grooves (38, 48), attached to each other by a bridge (54), engage the male ribs (26, 32). With the profiles (16, 20) engaged, the male rib (28) pushes against the bridge (54) and thereby pushes the bridge against the packaging film during attachment such that the profiles (16, 20) are stabilized during sealing to the packaging film. As part of a pre-made zipper (10), the male rib (28) can be attached to the bridge (54) to form a barrier seal within the zipper (10).
