ABSTRACT:
A reclosable extruded plastic fastener for joining sheet material such as walls of bags, and method of making the same. The fastener comprises a grooved female profile and a complementary hook-headed male profile, and a stabilizing structure especially advantageous when pressing the profiles together into closed fastener assembly. The female profile has a generally square base with at least one stop shoulder to minimize tipping of the female profile about a thin, thermal bridge minimizing, heat transfer limiting stem. The hooked jaw arms of the female profile may have various geometric shapes. The male profile has an interhooking barb which interengages with the hooked jaws of the female profile. Stabilizing ribs are spaced from the head, but the rib at the inner side of the head is closer to the head than at the other or outer side, so that there is a desirable differential fastener separating relationship retaining the fastener efficiently with greater hold against opening due to internal bag forces.
