Gold Glitter Film

When GAOFEI factory produces gold glitter film, the composite structure of the film material is precisely calculated. An elastic buffer layer is embedded between the CPP substrate and the coating layer, this layer is made of thermoplastic polyurethane material, which can not only absorb the mechanical stress during the processing to prevent the coating from cracking, but also adapt to the differences in the coefficient of thermal expansion of different substrates. Ensure the flatness after compounding, the surface of the golden onion structure is covered with a nano-scale hydrophobic coating. Its contact Angle has been optimized to enable water droplets to form complete spheres on the membrane material surface and roll off quickly, this feature not only enhances the membrane material's stain resistance but also makes cleaning and maintenance easy and efficient.

Product performance

The metal layer of traditional gold onion film is mostly electroplated, which is prone to oxidation and blackening due to changes in environmental humidity, the aluminum-coated layer of GAOFEIgold glitter film is formed through vacuum physical deposition technology, its atomic arrangement density is much higher than that of the electroplating layer, which can effectively prevent the penetration of oxygen and water vapor.

In combination with the optical sealing effect of the medium layer, the membrane material can still maintain the purity of its gold color and the uniformity of its luster after long-term use, even when exposed to ultraviolet radiation, there will be no obvious color fading or weakening of light efficiency.

The molecular chain structure of the CPP substrate has been specially modified, and its crystallinity and orientation degree are precisely regulated, this enables the film material to maintain its stiffness while having excellent flexibility, allowing the gold glitter film to easily meet the complex processing requirements such as the irregular structure of packaging boxes and the curved backplane of electronic products.

The UV absorber in CPP substrates can absorb most short-wavelength light and prevent yellowing caused by polymer chain breakage, the silicon oxide barrier layer of the aluminum-coated layer can maintain its density for a long time and is not prone to hydrolysis even in a high-humidity environment.

The fluorine content of the surface hydrophobic coating has been optimized, which not only ensures wear resistance but also avoids the decline in stain resistance caused by coating peeling, these designs enable the membrane material to maintain stable performance in outdoor exhibitions, storage and transportation scenarios.
