A bag structure especially adapted to be made from bag body web material, and fusibly incompatible extruded plastic zipper, comprises a pair of zipper strips having reclosable zipper profiles located below upper ends of pull flanges. Fused connecting anchors extend from the zipper strips through holes in the material of the bag body material and thereby permanently attach the zipper strips to the bag body material. Anchorage of the bag body material may be in groove sockets provided by the zipper strips. The zipper strips may be located on the inside or the outside of the bag structure. A pilfer evident seal may be provided along the pull flanges and require destruction of the seal to gain access into the bag through the reclosable zipper. Method of making the bag structure is also disclosed.
