Before we dive into the specifics of 8K and 4K sun films, it’s crucial to understand the basic technology behind these products. Sun films, also known as window tints, are thin laminates applied to car windows to reduce the amount of sunlight entering the vehicle. These films are designed to block ultraviolet (UV) rays, visible light, and infrared radiation, which contribute to heat buildup inside the car. The effectiveness of a sun film is measured by several factors, including:

• UV Rejection: The percentage of harmful UV rays blocked by the film. High-quality sun films can block up to 99% of UV rays, protecting your skin and the car’s interior from sun damage.
• Infrared Rejection (IRR): The percentage of infrared radiation blocked by the film. IRR is a significant factor in reducing heat inside the car. Films with high IRR ratings keep the interior cooler, reducing the need for air conditioning and improving fuel efficiency.
• Visible Light Transmission (VLT): The percentage of visible light that passes through the film. Lower VLT percentages mean darker tints, which provide more privacy but may also reduce visibility, especially at night. It’s essential to comply with local regulations regarding VLT levels.
• Total Solar Energy Rejected (TSER): The overall percentage of solar energy rejected by the film. TSER is a comprehensive measure that considers UV, visible light, and infrared radiation. Higher TSER values indicate better heat reduction.

Sun films are typically made from multiple layers of polyester film, with various coatings and treatments applied to enhance their performance. These coatings can include UV absorbers, infrared absorbers, and metallic particles that reflect solar energy. The quality of these materials and the manufacturing process significantly impact the film’s performance and durability.
