Abstract
A zipper closure for use in a package includes first and second closure strips. Each of the first and second closure strips includes at least one closure profile and a flange. The flange of the first closure strip includes outer and inner flange portions. The outer flange portion of the first closure strip encompasses and is integrally connected to the inner flange portion of the first closure strip at a bending point. The inner flange portion of the first closure strip includes the at least one closure profile. The inner flange portion of the first closure strip has a length less than the length of the outer flange portion of the first closure strip. The closure profile of the first closure strip is located between an open end of the inner flange portion and the bending point.
