Preferential bend structure and articles containing said structure

摘要

A preferential bend structure may have a first face and an opposing second face. The preferential bend structure may comprise at least a base layer and an auxiliary layer, wherein a first deforming force applied to the first face results in a first deflection and a second deforming force applied to the second face results in a second deflection which is equal to the first deflection, and wherein the second deforming force is not equal to the first deforming force.
