A resealable bag enclosure includes a body portion configured to hold a product and a zipper attached to the body portion. The zipper comprises a first zipper half and a second zipper half, each with interlocking profiles that repeatedly mate and separate to seal and open the bag enclosure. A tab extends from the first or second zipper half, featuring a scalloped shape. The scalloped shape reduces the risk of snagging during sealing in an auto bag opening machine or decreases the force required to open the zipper by ensuring only one interlocking profile opens at a time. The scalloped shape includes curved indentations on opposite lateral edges of the tab, smoothly transitioning to a linear edge. The tab may be one of multiple tabs forming a curved waveform with the consumer-facing edge of the zipper.
