A flexible package includes a package surrounding wall having a side edge and a mouth. A recloseable zipper is provided along the mouth for selective opening and closing of the mouth. The zipper includes first and second closure profiles. The first closure profile has a first closure member and a first flange. The second closure profile has a second closure member and a second flange. The first and second closure members are constructed and arranged to selectively interlock. A slider device is constructed and arranged to selectively open and close the mouth. A first seal region and a second seal region are provided. The first seal region permanently secures together the first and second flanges of the first and second closure profiles. The first seal region has a first length extending from the side edge. The second seal region permanently secures together the first and second closure members of the first and second closure profiles. The second seal region has an end edge extending a second length from the side edge. The second length is greater than the first length, and is at least 25% of the length of the slider device. In one embodiment, the second seal region is a continuous, uninterrupted extension from the side edge to the end edge. In another embodiment, the second seal region comprises first and second seal sections separated by a gap.
