- Biaxially oriented films containing polyethylene 1,2,6-naphthylene dicarboxylate as the main polymer component have excellent mechanical properties, thermal properties and heat resistance. And its production is also increasing.
- the thickness of the base dielectric film must be reduced.
- the reason why the thickness of the film as the dielectric material is reduced is that the capacitance of the capacitor is (a) proportional to the dielectric constant of the dielectric material and the electrode area, and (b) inversely proportional to the film thickness.
- the capacitance per unit volume of the dielectric material is inversely proportional to the square of the film thickness and proportional to the dielectric constant, the use of a dielectric material having the same dielectric constant makes the capacitor smaller or larger. This is because if capacity is to be increased, it is essential to reduce the film thickness.
- This workability mainly relates to the slipperiness of the film.
- a method of improving the slipperiness a method of giving fine irregularities on the film surface is known and used.

- the number of inert inorganic fine particles per unit area of the ultra-thin film decreases in the ultra-thin film manufacturing method.
- the distance between the fine particles on the film surface is increased, and as a result, the film surface becomes flat and the slipperiness is reduced.
- ultra-thin films have low rigidity, and the films are easily adhered to each other, which is a factor that reduces the slipperiness. Therefore, in order to compensate for the decrease in the slipperiness due to the thin film, it was necessary to increase the concentration of the inert inorganic fine particles or increase the particle diameter as the film thickness was reduced.
