Abstract

A reclosable bag is formed of walls defining a closure with a mouth. The closure includes an asymmetric arrowhead male profile extending along an internal surface of one of the walls and a female profile having stubs adapted to interengage with said male profile and extending along an internal surface of the other wall.
Both profiles also include stabilizer wedges on both sides thereof and parallel thereto across the width of the bag. The stabilizer wedges give the zipper formed by the male and female profiles a wide-track feel, and determine the force required to open the bag both from inside and from outside.
