| titleOfInvention | Manufacturing method of biaxially oriented polyester film |
| abstract | The present invention relates to a biaxially oriented polyester film, wherein a film made from conventional polyester has a processing speed, for example, a printing process for packaging, or a magnetic coating for magnetic recording media, calendaring, and slitting. As the surface of the film is worn out due to the increase in contact with the roll, problems such as post-processing process or product characteristics (quality) occur.n n n Accordingly, in the present invention, in order to improve the hardness of the film in polyester, 0.03 to 0.21% by weight of aerosol-based fine silica particles having an average particle diameter of 0.02 to 0.1 µm having a hardness of 6 or more, and inert particles B having different particle diameters, The polyester is prepared by using a biaxially oriented polyester film in a range in which the inert particles C satisfy a specific dosage ratio, and the prepared polyester can be applied to both a transesterification method and a direct exchange reaction method, and a reactor Using either batch or continuous type, it is possible to produce a film that can satisfy both winding properties, running properties and electronic properties simultaneously. The production method of such biaxially oriented polyester film provides excellent electronic properties, running properties, abrasion resistance and repeated durability. It is to be able to obtain a good film. |
