Abstract
A method of making packages having a reclosable zipper closure by a vertical form, fill and seal process. The method includes providing a pocket in a film web into which a zipper closure is positioned and attached. The film web is folded and sealed to form side panels and seams, which result in a package. The pocket provides an internal tamper evident-structure for the package. An external tamper evident-structure can be provided between the distal ends of the mating profiles of the zipper closure.
