17. The bag of claim 1 further including a peel seal downwardly adjacent and parallel to said weakened portion thereby forming a peal seal relationship between interiors of said opposing panels.
18. A tamper-evident zipper assembly used to open a mouth, the zipper assembly comprising:
a zipper having a first profile and a second profile, the first profile being fastened to the first panel and the second profile being fastened to the second panel; and
a slider attached to the zipper to move from a first position wherein said first and second profiles are attached to each other, and to a second position wherein at least a portion of the first and second profiles are detached from each other, the slider initially being in the first position and protruding from an opening in one of the panels and wherein prior movement of said slider toward said second position is evidenced by tearing of at least a portion of one of said opposing panels thereby forming a mouth.
