Classification and Application of Polyester Film

1.Electrical insulation film
Because of its good electrical, mechanical, thermal and chemical inertia, good insulation performance, high resistance to wear voltage, special for electronic and electrical insulation materials.

2.Capacitance film
It has the characteristics of high tensile strength, high dielectric constant, low loss factor, good thickness uniformity, good electrical performance, large electrical resistance, etc. It has been widely used in capacitor dielectric and insulation layer. 

3.The card protection film 
It has good transparency, high stiffness, good thermal stability, smooth surface excellent winding performance, uniform vertical and horizontal tensile performance, and has excellent waterproof, oil and chemical resistance performance. It is specially used for protective packaging of pictures, certificates, documents and office supplies, so that it can be smooth and beautiful after hot stamping as a protective film, and can keep the original clear and not deformed. 

4.Universal film 
It has excellent strength and dimensional stability, cold resistance and chemical stability, widely used in composite packaging, photographic film, metal evaporation, recording and video and other substrates.
