A polymeric film including a major surface having a plurality of intersecting extended structures is described. For at least a majority of the structures in the plurality of extended structures: each structure extends along a length of the structure, has an average width along a direction transverse to the length and generally along the first major surface, and has an average height along a direction generally perpendicular to the first major surface; and the average width of the structure may be in a range of 1 to 200 micrometers, the average height of the structure may be in a range of 1 to 200 micrometers, and the length may be at least 3 times the average width. The extended structures may be randomly or pseudorandomly oriented and may be formed by microreplicating a surface of a paper.
