The biaxially oriented single-layered film receives stresses in the range of 500 kg/cm.sup.2 to 1500 kg/cm.sup.2 each in the machine and transverse directions of the film. The multilayered film receives stresses in the range of 300 kg/cm.sup.2 to 1250 kg/cm.sup.2 each in the machine and transverse directions of the film. Thus, the molding stability in biaxial orientation of a nylon film is improved and the thickness accuracy of a resulting film is improved.
