Product Description
Heat Segmented Traffic Sign EGP Reflective Film Sheet Roll
Introduction to reflective film:
Brief: Reflective film for road is a specialized material designed to enhance visibility and safety on roadways. It is applied to road signs, markings, and vehicles, reflecting light back to its source, ensuring better visibility during nighttime and low-light conditions. It improves driver comprehension of traffic information, reduces the risk of accidents, and withstands various weather conditions. With a lifespan of several years, it offers long-term benefits in terms of improved road safety and visibility.
The five layers of material composition in reflective film are:
1. Face Film: The outermost layer, often made of durable materials like acrylic or polyester, protects the reflective film from environmental elements, such as UV rays and harsh weather conditions.
2. Adhesive Layer: This layer bonds the reflective film to the surface it is applied to, ensuring secure adhesion and longevity of the film.
3. Microprismatic Layer: Composed of tiny prismatic structures, this layer is responsible for reflecting light back to its source, making the film highly visible and enhancing its reflective properties.
4. Reflective Layer: The reflective layer contains glass beads or reflective pigments that further enhance the film's reflective capabilities, allowing it to reflect light efficiently.
5. Liner Layer: The bottom layer, typically made of silicone-coated paper or film, protects the adhesive layer during storage and handling, and is removed before the film is applied.
These five layers work together to create a robust and highly reflective film that enhances visibility and safety in various applications, including traffic signs, vehicle markings, and other reflective surfaces.
The production process of reflective film:
1. Base Material Preparation: A base material, such as a polymer film, is prepared to serve as the foundation for the reflective film. It is typically made from durable and weather-resistant materials.
2. Coating Application: A reflective layer is applied to the base material. This layer contains glass beads or microprismatic elements that will reflect light. The coating may be applied through techniques like lamination or extrusion.
3. Bead Embedment: Glass beads or microprisms are embedded into the wet coating layer. These beads or prisms are precisely placed to ensure optimal light reflection properties.
4. Curing or Drying: The coated film is then cured or dried, depending on the manufacturing process. This step ensures that the coating adheres securely to the base material and becomes fully functional.
5. Finishing and Cutting: The reflective film is trimmed, inspected for quality, and cut into desired sizes or shapes. It may also undergo additional treatments, such as the application of an adhesive backing for easy installation.
6. Quality Control: Rigorous quality control measures are implemented to check the reflective film for any defects, ensuring that it meets the required specifications and standards.
7. Packaging and Distribution: The finished reflective film is packaged and prepared for distribution to road signage manufacturers, government agencies, or other customers involved in road safety.
Throughout the production process, strict quality control procedures are followed to ensure the reflective film's performance and longevity on road surfaces.
