Abstract
A vertical form fill and seal apparatus is used to manufacture reclosable containers. A plastic zipper segment is provided with a double seal flange configuration wherein two zippers are provided for adjacent reclosable containers, one reclosable container being upside down and the other being rightside up. The zipper segment is initially provided on the web with the first flange sealed to the web. A tube is formed so that lateral edges are folded over and sealed to the second flange. A cut is thereafter formed by the sealing bars to separate the two reclosable containers from each other.
