OPP Holographic Laser Film

China OPP Holographic Laser Film by GAOFEI selects optical-grade polyester or polypropylene film as the substrate and uses nanoimprint technology to form a micron-sized periodic microstructure array on the film surface, the grating spacing is precisely controlled within 300-800 nanometers to form an interference grating layer. Subsequently, by using magnetron sputtering or vacuum coating processes, multiple layers of metal oxide dielectric layers with different refractive indices are alternately deposited, with each layer's thickness precisely reaching the nanometer leve.

These dielectric layers work in synergy with interference gratings, presenting rich and diverse optical colors and dynamic visual effects through the interference and diffraction effects of light, the surface of the membrane material is then coated with a high-strength wear-resistant coating, effectively enhancing its scratch resistance and environmental adaptability, and forming a complete structural system that integrates optical properties and physical protection.

Parameters

Application scenarios

OPP Holographic Laser Film is widely used in the packaging of high-end products such as luxury goods, cosmetics, tobacco and alcohol, through brilliant dynamic optical effects and exquisite holographic patterns, it enhances the added value of products and brand recognition, and strengthens consumers' visual memory and purchasing desire.

The product takes advantage of its unique optical interference characteristics to create anti-counterfeiting labels that are difficult to replicate, through the changes in light effect at specific angles and the details of microstructure, it can quickly verify the authenticity of the product, effectively combat counterfeit and shoddy behaviors, and protect the brand rights and interests of enterprises.

Advantage

OPP Holographic Laser Film has a precise design of multi-layer dielectric film systems and microstructure gratings. The dielectric laser film can achieve precise regulation of the full spectral band, it can not only present the seven-color light effect of traditional laser films, but also achieve selective reflection and transmission of light of specific wavelengths through customized film system design, create highly technological optical effects such as aurora gradient and holographic stereoscopic, meeting the strict visual differentiation requirements of high-end products.

Compared with traditional aluminum-coated laser films, our OPP Holographic Laser Film uses an inorganic oxide dielectric layer instead of the metal aluminum layer, effectively avoiding problems such as metal oxidation and corrosion, in harsh environments such as high temperature, high humidity, and strong ultraviolet rays, it can still maintain stable light efficiency, and the color persistence is increased by more than three times. Ensure the visual expressiveness of the product during long-term use.
