Characteristics of Polyester Film

Characteristics of Polyester Film

1. The mechanical properties of the film, such as tensile strength, elongation at break and elastic modulus, are significantly enhanced.

2. Impact strength and bending resistance increase.

3. Improved aging resistance.

4. The refractive index increases, the surface gloss increases, and the transparency of the film is improved.

5. Increase the width, reduce the thickness, increase the area coefficient, improve the utilization rate of the material and improve the uniformity of the film thickness.

6. Improved electrical performance.

7. Reduce the infiltration of water vapor, oxygen and other gases.

8. Improve the film surface smoothness, flatness, dimensional stability, wear resistance, can also reduce the heat shrinkage.
