Nickel plating on PET film

Nickel plating on PET film is a process that uses polyethylene terephthalate (PET) film as the substrate, and uniformly covers its surface with a layer of nickel metal through a series of precise surface treatment processes and nickel plating techniques. This composite material not only inherits the excellent properties of PET film, such as good optical performance, mechanical strength, chemical stability, and processability, but also endows conductivity, corrosion resistance, and electromagnetic shielding through nickel plating, greatly expanding its application fields.

Characteristics of Conductive PET Nickel Film Products

1. Excellent conductivity: The nickel plating layer provides excellent conductivity for PET film, making it suitable for applications that require conductivity, such as electronic components, touch screens, electromagnetic shielding, and other fields.

2. High corrosion resistance: Nickel metal has good corrosion resistance and can effectively resist the erosion of various chemicals, extending the service life of PET film.

3. Enhanced mechanical properties: After nickel plating, the surface hardness of PET film is increased, and its scratch resistance and wear resistance are enhanced, while maintaining the original high strength and toughness of PET film.

4. Stable optical performance: PET film itself has good transparency and glossiness, and nickel plating treatment has little effect on its optical performance, making it still suitable for occasions that require good optical effects.

5. Good processability: PET film is easy to process and shape, and can still undergo cutting, stamping, bending, and other processing operations after nickel plating, making it convenient to produce various complex shaped components.
   

   

Production process of vacuum sputtering nickel plated PET

1. PET film pretreatment: Cleaning, degreasing, dust removal and other pretreatment of PET film to improve the adhesion and uniformity of the coating.

2. Surface activation: Chemical or physical methods are used to activate the surface of PET film, making it easier to bond with the coating.

3. Nickel plating treatment: Using electroplating or chemical plating methods to uniformly coat a layer of nickel metal on the surface of PET film. The thickness and uniformity of the coating can be adjusted according to specific needs.

4. Post processing: Clean, dry, inspect, and cut the PET film after nickel plating to ensure that the product quality meets the requirements.
