Abstract
A closure arrangement for a reclosable polymeric bag is disclosed, the closure arrangement comprising convex and concave areas that facilitate opening the bag. To initially open the bag, first and second films are separated from each other by tearing perforations. Next, interlocked closure profiles are detached from each other by grabbing onto gripper ridges and pulling the opening of the bag apart. If the first or second film becomes tucked into the groove left by the perforations such that the gripper ridges are difficult to access even after tearing the perforations, then the end of the opening may be flexed up or down, thereby causing separation of the convex area and concave area to provide access to the gripper ridges.
