Abstract
A reclosable zipper including a first closure profile, a second closure profile constructed and arranged to selectively mate with the first closure profile, and a web arrangement joining the first closure profile and the second closure profile. The web arrangement includes a plurality of tear regions radially spaced across the web arrangement. Each of the tear regions has a lower shear strength than the remaining portions of the web arrangement. The tear regions may include multiple layers and have geometric shapes, such as a T, a trapezoid, a triangle, a round, and a rectangle. In some embodiments, there is a second web arrangement joining the first and second closure profiles. This reclosable zipper can be used on a flexible package to create a tamper-evident flexible package. Methods of operation are described.
