An in-line method is disclosed for securing a closure system onto a discrete pouch. The method includes advancing a discrete pouch through a first station in a machine direction with the closed bottom of the pouch being the leading edge and a first major surface of the pouch faces upward. The first major surface is folded upon itself to form a lip having an exposed first surface while a second major surface of the pouch has an exposed inner surface. The method also includes routing the pouch to a second station where a closure system is transversely attached across the exposed inner surface. The closure system includes an opening/closing mechanism. The method further includes routing the pouch to a third station where the lip is unfolded and opposite ends of the lip are secured to the outer surface of the closure system.
