Abstract

A plastic bag having a reclosable plastic zipper is provided with a tamper-evident, non-reclosable peel seal formed by coextruding an adhesive onto a side strip adjacent to the interlocking zipper. The coextrusion causes the adhesive to preferentially adhere to the side strip when the peel seal is broken. A method for manufacturing the reclosable plastic zipper includes the steps of coextruding a zipper profile including a plane area with an adhesive on the plane area, slitting the profile lengthwise, and folding lover one of the resulting sides of the zipper to interlock them with one another.
