BIAXIALLY ORIENTED POLYETHYLENE TEREPHTHALATE FILM |
摘要 |
<p>The present invention provides a biaxially oriented polyethylene terephthalate film which has minimal curling, has superior suitability for machining, and is an ideal base material film, and whereby dimensional changes in various steps can be reduced particularly when the film is used as a base material film for a flexible device. This biaxially oriented polyethylene terephthalate film is made using at least a polyethylene terephthalate resin, wherein the average ((nMD+nTD)2) of the refractive index nMD in the length direction of the film and the refracfive index nTD in the width direction thereof is 1.655-1.70, and the refractive index nZD in the thickness direction of the film is 1.490-1.520.</p> |
