Silver PET transfer film uses PET as a carrier and transfers a silver metal layer onto the surface of the target substrate through a release layer + vacuum metal plating (aluminum/silver) + composite transfer process. Its core applications are concentrated in packaging, printing decoration, and optics, achieving metallic texture, high reflectivity, or anti-counterfeiting effects. The following provides a detailed explanation of the principles and applications.

Core Principle
Silver PET transfer film is essentially a functional carrier film. The core principle is to "first create a silver metal layer on the PET film, then completely transfer it to the substrate, and the PET film can be peeled off and recycled."
Substrate and Release Pre-treatment: Using PET film as a support, a release layer (such as silicone oil) is first applied to ensure that the subsequent metal layer can be easily peeled off, while also ensuring dimensional stability and high-temperature resistance.
Vacuum Metal Plating: In a high-vacuum environment, aluminum (the mainstream material) or silver wire is heated and evaporated, and uniformly deposited on the PET release surface to form a nano-scale dense silver metal layer; advanced processes can use magnetron sputtering to improve the uniformity and reflectivity of the silver layer.
Lamination and Transfer: A transfer adhesive is applied to the surface of the metal layer, and then laminated and pressed onto the target substrate (cardboard, paper, leather, fabric, etc.); at this point, the adhesion between the adhesive layer and the substrate is greater than the adhesion between the metal layer and the PET release layer. After peeling off the PET film, the silver metal layer is completely transferred to the surface of the substrate, forming a metallic coating.
Post-treatment (optional): A protective layer can be added to prevent oxidation, or laser embossing can be used to achieve anti-counterfeiting and decorative effects.

Main Applications
1. Packaging and Printing: High-end Metallic Texture and Anti-counterfeiting
Metallized Cardboard/Paperboard: Transferred onto the paper surface to form "metallized cardboard," replacing large-area hot stamping, used for cigarettes, cosmetics, health products, gift boxes, etc., providing strong metallic luster at a lower cost than aluminum foil lamination, and being more environmentally friendly.
Anti-counterfeiting Packaging: Combined with laser embossing to create laser silver cardboard, used for anti-counterfeiting labels and packaging boxes for tobacco, alcohol, pharmaceuticals, etc., increasing the difficulty of counterfeiting.
Flexible Packaging Lamination: Transferred onto plastic film to improve barrier properties (oxygen, moisture, and light barrier), extending the shelf life of food, medicine, and cosmetics, while also enhancing the appearance and texture.
2. Decoration and Transfer Printing: Flexible Adaptation to Various Substrates
Leather/Textiles: Transferred onto artificial leather and fabrics to create metallic patterns and logos for shoes, bags, clothing, and home decorations, replacing traditional electroplating/hot stamping with a more environmentally friendly and efficient process.
Heat Transfer Materials: Used for garment heat transfer printing and sports equipment logos (such as reflective silver letters), transferring silver patterns onto cotton, polyester, and other fabrics through heat pressing.
Building Materials Decoration: Used for composite panels and films to achieve metallic texture decorative effects, suitable for furniture, home appliance panels, etc.
3. Optical Field: High Reflectivity and Light Control
Silver PET transfer film (especially the silver-plated type) is used in optical components due to the high reflectivity of the silver layer (up to 96%+):
LED Backlight Modules and Light Boxes: Transferred onto optical films or substrates to improve light reflection efficiency, reduce light loss, and make lighting more uniform and energy-efficient.
Reflective Products: Used for reflective signs and safety clothing to enhance visibility at night.
