Prismatic retro-reflective tape is manufactured using a specialized process that involves the creation of micro prisms within a transparent film. These micro prisms are responsible for the tape’s exceptional brightness and reflective properties.
The manufacturing process begins with the production of a base material, typically a durable and weather-resistant polymer film. This film serves as the foundation for the retro-reflective tape.
A micro prism array is embossed onto the back of this film making it retro reflective. The prisms are strategically shaped and positioned to ensure that light entering the tape is redirected back in the direction it came from. This unique property allows the tape to appear bright when illuminated by a light source, such as headlights or flashlights.
At this point, some films are metalized on the back to enhance reflectivity (Metalized Prismatics). Others are backed with a white sheet that is separated from the prism array by an air layer (Air Backed Prismatics). Metalized prismatic films are typically used for dynamic applications like the sides of trucks, railroad cars, gate arms, and other situations where the tape needs to be rugged. Air backed films are mostly used for signs.
After the prisms are formed, a protective layer is often added to shield the tape from environmental factors such as UV radiation, moisture, and abrasion. This protective layer helps to maintain the tape’s reflective properties and extend its lifespan.
Next, a layer of adhesive is applied to one side of the film, allowing for easy application onto various surfaces.
The final product is then cut into rolls of various widths and lengths, ready for use in a wide range of applications where enhanced visibility and safety are required.
