What is the use of pet film?

June 08, 2023

The pet film is a relatively comprehensive packaging film. It has good transparency and luster; it has good air tightness and aroma retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures. The pet film has excellent mechanical properties, its toughness is the best among all thermoplastics, and its tensile strength and impact strength are much higher than those of ordinary films. It has good strength and dimensional stability and is suitable for secondary processing such as printing and paper bags. . The pet film also has excellent heat resistance, cold resistance, and good chemical resistance and oil resistance. With the development of special functional films, the new use of pet film has also emerged, which can be produced into mobile phone LCD protective film, LCD TV protective film, mobile phone buttons, etc. In addition to the above, what other uses of pet film, please see Below:

1, pet film is mainly used in electrical, insulation, packaging, magnet containers, film, tape, floppy disk, video and entertainment software; its application range, such as bronzing film, aluminized film, printing film, packaging film, packaging Materials, composite materials, laser anti-counterfeiting composite films, electrical insulation materials and capacitors.

2, antistatic pet film

Since the pet film is subjected to friction to generate static electricity, water-soluble polyaniline and a specific polyester-based binder are applied to the pet film to maintain both transparency and excellent antistatic properties.

3. PET film for digital printing

This pet film provides good ink adhesion, print quality and color reproduction, and has very good flattening properties.

4, nano pet film

High transparency and gloss: Nanoparticles with particle sizes between 1 and 100 nm are smaller than the wavelength of visible light and have less effect on film transparency.

5, film (guard card use)

The paper carrier publications, packaging materials and other printed materials are finished by film finishing after printing, and the graphic is protected, and the visual effect is better. Especially the matt film does not have wide-angle and excessive light diffuse refraction of light, and it is softer. A new feeling of deep, noble and luxurious.

6, the application of transparent electrodes

Through the study of the interface characteristics between the luminescent polymer material and the metal electrode, the long-term working stability of the device is achieved.
