Abstract
The end stop is formed on ends of a zipper for a reclosable package or bag by ultrasonically welding the ends of the zipper profiles together so as to form a raised portion. This prevents the slider from being pulled off of the ends of the zipper. Additionally, in the ultrasonic welding step, an indentation is formed into which glue is added thereby forming a lateral protrusion on the side of a zipper profile. This increases the strength of the end stop and increases the slider pull-off force which can be resisted.
