Abstract
Material for bags with flexible sidewalls having reclosable separable plastic profile bag mouth closures comprising flexible sheet material providing the bag body and sidewalls. The bag mouth closures comprise strips having separably interlockable complementary resilient plastic profiles and lateral pull flanges of greater thickness than the sheet material extending from one side of each of the base portions. The opposite side of each base portion is generally aligned with its profiles. The base portions and lateral pull flanges are secured in laminar relation to marginal portions of the sheet material, and with distal edges of the pull flanges directed toward bag top edges of the marginal sheet portions.
