Abstract
A zipper assembly for a reclosable package or bag is disclosed. The zipper assembly includes two profiles with flanges and internal interlocking elements on the interior of the flanges. The exterior of one of the flanges includes two exterior parallel press-to-close profile-like interlocking elements which are brought into engagement with each other by folding the flanges of the zipper assembly. This increases the burst handling capability of the zipper assembly and the package or bag to which it is attached. Alternatives include substituting a peel seal for the exterior interlocking element as well as an exterior label or sticker to maintain the flanges in a folded configuration.
