<p>Ionomer resin sheet is stretched in one direction in the plane of sheet to give uniaxial anisotropy, and then heated above the melting point under pressure to cause relaxation of the anisotropy. After cooling, a sheet of biaxial anisotropy is obtained. The degree of anisotropy depends on the initial stretching, heating temperature, heating time and pressure.</p>
