Abstract
The invention is a mating film. The mating film comprises a base sheet having a first major surface. A plurality of generally parallel ridges project from the first major surface. The ridges comprise a stem portion attached to the base sheet and generally upright from the base sheet. A head portion of each ridge is spaced from the first major surface and extends generally laterally from the stem portion so as to define a lateral distance. The center of each stem portion of each ridge is spaced from the center of each adjacent ridge stem portion by a distance greater than about 2 times lateral distance defined by the head portion.
