Method of imparting a mono-axial or multiaxial stiffness to extruded materials and products resulting therefrom

摘要

A method of modifying the stiffness properties of a material by imparting grooves or cross sectional shapes to a surface or multiple surfaces of the material is described. Materials made by this method, and products made with the material, such as nasal dilators, packaging, construction materials and medical devices, are also described.
