Analysis of Optical Properties of PET Aluminum Coated Film: Excellent Performance in Reflection and Transmittance

In the field of materials science today,PET aluminum plated filmAs a high-performance composite flexible packaging material, it has attracted much attention due to its unique optical properties. Especially the PET aluminum plated film produced by Advanced Institute (Shenzhen) Technology Co., Ltd. stands out in many application fields due to its excellent reflective and translucent properties.

1、 Basic Overview of PET Aluminum Coated Film

PET aluminum plated film is a composite material formed by vacuum aluminum plating process, which coats a very thin layer of metallic aluminum on the surface of PET film. This material not only inherits the excellent physical and mechanical properties of PET film, such as high strength and transparency, but also has unique optical and barrier properties due to the addition of a metal aluminum layer.

2、 Reflection performance of PET aluminum coated film

PET aluminum coated film exhibits excellent reflective performance. The thickness of the aluminum coating is generally 0.02-0.06 μ m, and this extremely thin metal layer enables PET aluminum coating to have high reflectivity in the visible, ultraviolet, and infrared ranges. Especially in the visible light range, the reflectivity of PET aluminum coated film can reach over 95%, presenting a significant metallic luster and mirror effect. This high reflectivity not only enhances the decorative effect of the material, but also makes PET aluminum plated film have broad application prospects in fields such as solar energy utilization and reflective insulation.

In addition,PET aluminum plated filmThe ability to reflect ultraviolet and infrared rays is particularly outstanding. Due to the higher reflectivity of aluminum to ultraviolet and infrared radiation compared to most metals, PET aluminum coating can effectively reduce the transfer of external heat while also providing some insulation to the internal temperature. This characteristic has shown great potential for the application of PET aluminum plated film in the fields of insulation materials and shading materials.

3、 Transparency performance of PET aluminum coated film

Although PET aluminum coated film performs well in terms of reflection performance, its transparency should not be underestimated. Through precise control, the transmittance of PET aluminum plated film can reach over 70%. This means that while maintaining a high reflectivity, PET aluminum coated film can also allow some light to pass through, thus meeting the needs of certain specific application scenarios.

It is worth noting that the transparency of PET aluminum coated film is not limited to the visible light range. In terms of infrared blocking, PET aluminum coated film can generally achieve an efficiency of 30-40%. This feature makes PET aluminum coated film perform better in terms of insulation, effectively reducing heat transfer and improving indoor or equipment comfort.
