The disclosure relates to a zipper design, with or without a leading flange, to improve front panel zipper fabrication and end use applications. The profiles of the zipper include a plurality of interlocking elements, which may include C-shaped, J-shaped or repeating male interlocking elements. In the unflanged version, a portion of the interlocking elements of one of the profiles is sealed directly to the interior of a bag on a first side of the front panel bag opening, while the base of the other profile is sealed on a second side of the front panel bag opening, aligned so that interlocking elements of one profile can interlock with interlocking elements of the other profile.
