Unlocking PET aluminum plated reflective film | From technological breakthroughs to revolutionary applications in multiple fields

In the field of materials science, the research and development of high-performance composite materials has always been the core driving force for industrial upgrading. PET aluminum coated reflective film, as a new generation of functional thin film materials, is causing technological changes in fields such as building energy conservation, new energy vehicles, and high-end packaging due to its unique metal polymer composite structure. Advanced Institute Technology has successfully broken through the performance bottleneck of traditional materials through independent innovation of vacuum coating technology. Its customized production of PET aluminum plated reflective film has achieved a visible light reflectivity of over 92% and an infrared barrier rate of 85%, becoming the preferred solution for customers in multiple industries.

1、 Technical Core: Precise Control of Vacuum Coating Process

PET aluminum plated reflective filmThe performance advantage of it comes from the precise control of the metal deposition layer during its preparation process. Advanced Institute Technology adopts magnetron sputtering and thermal evaporation composite coating technology to achieve uniform deposition of aluminum atoms on the surface of PET substrate in a Class 10000 clean room. This process achieves precise control of aluminum layer thickness within the range of 10-200nm by controlling sputtering power and evaporation rate.

Taking a well-known electronics company in Dongguan as an example, its OLED display screens have extremely strict requirements for reflectivity. The 18nm thick aluminum coating customized by Advanced Institute Technology achieves an average reflectivity of 91.7% in the 450-650nm wavelength range, which is 8.3 percentage points higher than the traditional vapor deposition process. This precision control enables the film to maintain high reflectivity while keeping the surface roughness below 0.8 μ m, effectively avoiding optical interference phenomena.

The substrate pretreatment during the coating process is also crucial. The plasma cleaning technology developed by Advanced Institute Technology can form an active layer with a thickness of 0.5-1nm on the surface of PET, increasing the adhesion of aluminum atoms by 300%. Verified by a third-party testing agency, after 100 friction tests, the aluminum layer detachment rate of its product is less than 0.05%, meeting the military grade adhesion standard.

The application case of the exterior curtain wall of a building in Shanghai shows that the use of advanced technology 100 μ m thick aluminum coated insulating glass can reduce the annual air conditioning energy consumption of the building by 22%. The film effectively blocks thermal radiation transfer by reflecting over 95% of mid to far infrared radiation, with a thermal resistance value (R value) of 2.8m ² · K/W, which is 40% higher than traditional Low-E glass.

In the field of Building Integrated Photovoltaics (BIPV), the double-sided aluminum plated film developed by Advanced Institute Technology has demonstrated unique advantages. Its 85% infrared reflectivity can reduce the operating temperature of photovoltaic modules by 8-10 ℃, increasing power generation efficiency by 3-5%. The application of a photovoltaic curtain wall project in Jiangsu Province shows that the BIPV system using this film increases the annual power generation by 126000 kWh and shortens the investment payback period to 4.2 years.

Real vehicle testing shows that this material can reduce the temperature fluctuation range of the battery pack to ± 2 ℃, significantly extending the battery cycle life.

In the field of automotive interior, the electromagnetic shielding performance of aluminum plated film is fully utilized. A case study of a luxury brand car model shows that after using an aluminum plated film shielding layer, the electromagnetic radiation intensity inside the car is reduced to below 0.4 μ T, which is 80% lower than the national standard limit. This material also has a 99.9% UV blocking rate, effectively protecting interior materials from light aging.

In the field of food packaging, the antibacterial aluminum plated film developed by Advanced Institute Technology is reshaping industry standards. By depositing nano silver particles on the surface of the aluminum layer, the film achieved a 99.99% inhibition rate against Escherichia coli and Staphylococcus aureus. The application of a certain dairy product enterprise shows that the shelf life of room temperature milk using this packaging has been extended to 180 days, and the shelf life loss rate has been reduced by 65%.

5、 Customized services: a leap from standard products to solutions

The digital customization platform established by Advanced Institute Technology can achieve full process control from requirement analysis to product delivery. Customers input more than 20 indicators such as application scenarios and performance parameters through the online configuration system, and the system automatically generates 3 sets of optimization solutions. The extreme environmental requirements proposed by a certain aerospace company (temperature resistance -55 ℃ to 150 ℃, reflectivity ≥ 90%) were matched with a 75nm thick aluminum coating solution through a platform, and the ground simulation test fully met the requirements.
