How to coat PET with metal film

PET (polyester film) is a common plastic material commonly used to manufacture various packaging bags, labels, electronic products, etc.PET surface coated with metal filmIt can increase its glossiness and aesthetics, while also improving its physical properties and chemical stability.

The metal film coating on PET surface requires the following steps:

1. Surface treatment: Firstly, the surface of PET film needs to be cleaned and treated. This is to remove surface dirt and impurities, and lay the groundwork for subsequent coating. Alkaline cleaning agents and organic solvents are usually used for surface cleaning and activation treatment.
   

   
   

2. Basic layer coating: Apply a basic coating layer on the surface of PET first, which can improve the adhesion between the metal layer and PET. The commonly used basic coating is chromium/copper composite layer or titanium/copper composite layer.
   

   
   

3. Metal plating: Plating another layer of metal on top of the base layer, commonly used metals include chromium, nickel, copper, silver, gold, etc. Among them, silver and gold are more common because they have high conductivity and good appearance. Metal plating can be achieved through methods such as physical coating, chemical coating, or vacuum coating.
   

   
   

4. Decorative coating: In order to improve the decorative effect and wear resistance of PET, a transparent or colored decorative coating, such as polyurethane, acrylic, etc., can be covered on top of the metal layer.
   

The plating of metal film on PET surface requires multiple steps to be successfully completed. This operation requires professional technical and equipment support, so it is best to entrust it to a professional metal surface treatment manufacturer.

Coating PET surface with metal film can increase its glossiness and aesthetics, while also improving its physical properties and chemical stability.

Here are some uses of PET coated metal film:

1. Packaging industry: PET coated metal film can be used to make high-end gift packaging, cosmetics packaging, food packaging, etc. The reflective effect and color brightness of metal film can enhance the attractiveness and added value of products.
   

   
   

2. Electronic industry:PET coated metal filmIt can be used to make exterior components, touch screens, and other electronic products such as mobile phones, tablets, and televisions. Metal film has good conductivity, which helps to improve the performance of products.
   

   
   

3. Printing industry: PET coated metal film can be used for printing greeting cards, commemorative medals, business cards, etc., with excellent decorative effects.
   

   
   

4. Automotive industry: PET coated metal film can be used for the production of automotive interior components, such as instrument dials, door handles, etc. Metal film can enhance the texture and durability of these components.
