Corona Treated PET Film
Corona-treated PET film is a transparent polyester film. It has gone through electrostatic treatment. This film has good adhesion and surface properties. It achieves the best combination of film and coating. This film resists corrosion and high temperatures. It is tough and sticks well to ink. It has a wide range of applications, including flexible packaging, printing, mold release, industrial product processing, and lamination.
- Corona treatment enhances surface tension.
- Suitable for a variety of coatings and adhesives.
- Improved ink adhesion and clearer printing.
- Customized production services are available.
Product Details of descriptions
Corona treated film is a transparent polyester film. Through special electrostatic treatment, this film has stronger surface tension. It can achieve the best state of adhesive strength and surface performance. In practical applications, coatings, adhesives, and inks adhere better to the film. Printing performance is also improved. The clarity and color brightness of printing are superior to ordinary films. It is suitable for high-end product packaging.
Corona treatment does not interfere with other film processing. Metallization and lamination can still be performed on the film. Corona treatment also improves the cleanliness of the film surface. It effectively removes impurities and dust from the film surface. Therefore, this film is also suitable for use in mold release applications. This film has a smooth appearance and high glossiness. It is more aesthetically pleasing when used for packaging books, stationery, and daily chemical products.
We offer customized production services. You can specify the film dimensions and corona treatment areas according to your requirements. Our film production has obtained ISO 9001 certification, ensuring a consistently high standard of quality. We welcome you to contact us for customized wholesale orders!
