PET polyester film has excellent physical and chemical properties, dimensional stability, transparency and recyclability. It can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields. With the development of special functional polyester film, new applications continue to appear.

Compressed air plastic film

Compressed air plastic film is made of two pieces of polyester film sealed together and filled with bubbles between them. In this way, compressed air provides a good cushioning effect for lighter articles. It can be cut, so it can package products of any shape or size. Since the main role of polyester film is to improve support, it is expected that a film of medium thickness (25um-75um) is more suitable.

Film covering (card protection purpose)

After printing, paper carrier publications, packaging and other printed materials are coated with film for fine processing, so that the pictures and texts are protected and the visual effect is better. In particular, the matt film has no diffuse refraction of wide-angle and excessive light, which gives people a new feeling of softness, profundity, nobility and luxury. Film coating can increase the depth and brightness of color, improve the color contrast, and make the pictures and texts waterproof, non sticky, oil resistant and wear-resistant. It improves the physical and mechanical strength of the paper such as tension value, smoothness, light aging, tear resistance and puncture resistance, suppresses the physical property of moisture absorption, reduces the deformation and damage of the paper products caused by the influence of moisture, and improves the rigidity and molding stability of the products. Even if the printed matter is exposed to sunlight, it can delay the fading process.

Antistatic PET film

Due to the electrostatic phenomenon caused by the friction of PET film, coating water-soluble polybenzamine and specific polyester adhesive on PET film can not only maintain its transparency, but also have excellent antistatic performance.
