Abstract:
Various apparatuses are disclosed including those that have curvature arresting properties. According to one example, the apparatus can optionally include a flexible first film, a second film and a first plurality of features. The first plurality of features can be disposed between the first film and the second film At least some of the first plurality of features are spaced apart from one another by a gap when the first film is not subject to an applied bending force or is subject to the applied bending force below a predetermined magnitude in one or both of the transverse direction and the longitudinal direction, and at least some of the first plurality of features contact one another to arrest a curvature of the first film when the applied bending force is at or above the predetermined magnitude.
