A flexible object comprising a polymeric film having a first surface and an opposite second surface. The polymer film has a plurality of holes extending from the first surface to the second surface and a plurality of raised lips protruding from the first surface, such that the holes are each raised by the plurality Surrounded by one of the openings. A method of making a polymer film comprising placing a polymer solution in a one sided mold having a plurality of protrusions extending from a bottom of the mold, wherein the polymer solution is characterized by inhibiting the polymer from external force flow Passing the viscosity of the mold; actuating the polymer solution to surround each of the plurality of protrusions; and curing the polymer solution. |
