Title: Biaxially oriented polyethylene-2,6-naphthalate film and manufacture thereof
IPC: C09D127/06
Filed: 1992-03-18
Abstract: PURPOSE:To manufacture a biaxially oriented polyethylene-2,6-naphthalate film which is less susceptible to the deformation and damage of a tape even through it is thin in the thickness, and a film having small unevenness in its thickness by adjusting its Young's modulus. CONSTITUTION:The biaxially oriented polyethylene-2,6-naphthalate film is featured such that longitudinal Young's modulus is 550kg/mm<2> or more and the transverse Young's modulus is 800kg/mm<2> or more, and the difference between them is 200kg/mm<2> or more. In the case where the longitudinal Young's modulus is 550kg/mm<2> or less, it is not suitable to magnetic tape because the tape extends and deforms. Also, in the case where transverse Young's modulus is 800kg/mm<2> or less and the difference between them is 200kg/mm<2> or less, the edge of tape extends and deforms like seaweed and, thus, the characteristics of tape are deteriorated. Furthermore, it is necessary to be 15% or less in the unevenness of thickness, and when exceeds 15%, it is not suitable because the tape varies largely in electromagnetic characteristics. Still further, the thickness is 12mum or less, preferably, 7mum or less in order to prolong the recording and reproducing time.
