ABSTRACT:
A flexible package is provided with a shrouded slide fastener closure. Fastener tracks are deformed at each end to provide an end stop to limit slider movement. A stop of reduced area with increased pull off force performance is provided. Features of the end stop include an L-shaped shoulder located above an underlying finger portion comprising an undeformed portion of the fastener tracks. The remainder of the end stop is formed by heating, softening and displacing portions of the fastener track material.
