摘要：
A film includes a first layer disposed on a second layer. The second layer is an adhesive layer. The first layer has a first major surface facing away from the second layer. The first major surface includes a plurality of structures protruding outwardly from the film and defining a plurality of angles between adjacent or intersecting structures. The plurality of angles includes at least two different acute angles. For each structure in at least a majority of the structures: the structure extends along a length L of the structure, has an average width W along a direction transverse to the length and along the first major surface, and has an average height H along a direction perpendicular to the first major surface, where 10 ≤ L/H ≤ 1000 and 10 ≤ L/W ≤ 1000.
