ABSTRACT:
A recloseable bag having a fastener assembly comprising two fastener profiles, each having a hinged double wall construction to prevent unintended opening of the bag due to internal forces exerted on the inside of the bag wall panels. The bag is easily openable when suh is intended by simple manipulation of pull flanges, thereby providing access to the interior of the bag. The hinged double wall construction also assures proper alignment of the fastener profiles across the length of the upper portion of the bag wall panels, making interlocking closure easy when pressure is applied on the outer walls of the bag behind the fastener profiles.
