Abstract
A method of making reclosable packaging utilizes a longitudinally extending web of film material having cutouts therein. A length of zipper strip substantially half the width of the web and having an attached slider is applied transversely across the web of film material with the slider positioned in the cut out. The web is folded longitudinally with the zipper attached to the web and the slider positioned in the cut out. The edges of the web are brought together longitudinally and seamed to form a tube. The opposite ends of the tube are sealed to form the package. The resultant bag has the slider seated in the cut-out where it is readily visible to a consumer.
