PROCESS FOR PRODUCING BIAXIALLY ORIENTED NYLON FILM |
摘要 |
The invention relates to processes for producing biaxially oriented single-layered and multilayered films. The biaxially oriented single-layered film receives stresses in the range of 500 kg/cm<2> to 1500 kg/cm<2> each in the machine and transverse directions of the film. The multilayered film receives stresses in the range of 300 kg/cm<2> to 1250 kg/cm<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. |
