ABSTRACT:
A peel seal zipper tape for reclosable plastic bags or packages includes a first and a second mutually interlocking zipper profile disposed on a top surface of a laminated film strip. The top surface is formed by a layer of a sealant material. The laminated film strip also has a bottom surface formed by a layer of a non-peel-seal material. In use, the laminated film strip is folded over enabling the zipper profiles to be interlocked with one another. In so doing, portions of the top surface of the laminated film strip face one another, so that they may be joined with a heat seal. The outside of the folded peel seal zipper tape, that is, the bottom surface of non-peel-seal material, is bonded to plastic sheet material from which reclosable plastic bags or packages are made. In the production of the bags or packages, the mutually facing portions of the laminated film strip are sealed together. The resulting seal gives a visual indication of having been broken when initially opened.
