| titleOfInvention | Biaxially oriented polyester film |
| abstract | (57) [Summary] [Purpose] The workability of handling the base film is good, and when the fixed magnetic head type digital audio tape is used, it is excellent in the restoring property of the tape forcibly stretched near the magnetic head, Disclosed is a biaxially oriented polyester film which has little distortion and output fluctuation, has good tape running properties and good audio characteristics (electromagnetic conversion characteristics), and is particularly useful for digital audio cassette tapes of the type without back coating. [Structure] A biaxially oriented polyethylene-2,6-naphthalate film, which has a longitudinal stress of 5% at 23% / mm 2 or more and a transverse stress of 5% at 13 kg / mm 2. 2 or more, the longitudinal residual elongation is 0.15% or less, and the transverse residual elongation is 0.20. % Or less, the surface roughness Ra is 5 to 25 nm, and 1 Biaxial for digital audio cassette tape, characterized in that the heat shrinkage in the longitudinal direction is 0.5% or less when heat-treated at 05 ° C. for 30 minutes under no load, and the film thickness is 3 to 6 μm. Oriented polyester film. |
