Biaxially oriented polyethylene-2,6-naphthalate film |
| abstract |
(57) [Abstract] [Purpose] Biaxially oriented polyethylene-2, which is useful as a base film for magnetic recording tapes capable of long-term recording and reproduction, especially compact cassette video tapes for small VTRs. 6-Providing a naphthalate film. [Structure] Young's modulus (Em) in the vertical direction is 500 kg / mm 2 As described above, the Young's modulus in the transverse direction (Et) is in the range of 1.5 to 3.0 times the ratio (Et / Em) to the Young's modulus in the longitudinal direction, and the film thickness exceeds 7 μm and 12 μm or less. Biaxially characterized in that the heat shrinkage in the lateral direction when heated at 5 ° C. for 30 minutes without load is 1.5% or less, and the surface roughness of the film is 0.005 to 0.010 μm. Oriented polyethylene-2,6-naphthalate film. |
