Polyester film is usually transparent, shiny film, rigidity, high hardness and toughness, good atmosphere and incense, and is one of the commonly used composite film substrates.
The polyester film has a very good printing performance, super stretch, and is very suitable for printing and aluminum -plated membrane materials. It occupies a large market position in the printing and aluminum plating industry.
Polyester film is a polymer material, high -temperature resistance, and the melting point has reached 260 degrees Celsius. Even if it is minus 70 degrees Celsius to minus 220 degrees Celsius, it still shows good toughness and toughness. It is very suitable for aluminum -plated materials.
The polyester film is an essential packaging raw material in the packaging industry. It has various functions such as dustproof, windproof, moisture -proof, etc., which can well protect the products inside, and its applications are widely used.
The main advantages of polyester film are reflected in the following aspects:
1. High stability, which can reach about 130 ° C at high temperature resistance for a long time, and can reach about 180 ° C within 1 hour.
2. Has low -fog and high light transmittance, high surface smoothness, and small thickness tolerance.
3. Base membranes have excellent mechanical strength and chemical properties.
4. In terms of environmental protection, there is no need to worry about the high degree of decomposition and soluble of polyclic film.
