What is the principle of PET micro-prismatic reflective tape?

The PET micro-prismatic reflective tape is a special structure of PET film that uses optical principles to retroreflect light back to the light source. The PET micro-prismatic reflective tape is composed of a film layer, a micro glass bead layer, a focusing layer, a PET micro-prismatic reflective tape picture, a reflective layer, an adhesive layer, and a peeling layer. Everyone knows that the reflection of light includes diffuse reflection and specular reflection. Why can the PET micro-prismatic reflective tape originally return light? This is mainly due to the PET micro-prismatic reflective tape containing high refractive index glass beads. When a beam of light illuminates the front surface of the beads at any angle within a certain range, due to the high refraction of the beads, the light is concentrated on the reflective layer on the back surface of the beads, and the reflected light from the reflective layer returns parallel to the direction of the incident light Formation of retroreflection. When many glass beads reflect at the same time, a bright scene will appear in front of you.

How to produce PET micro-prismatic reflective tape?

The production process of PET micro-prismatic reflective tape includes the following steps: 1). The sealing layer resin glue is coated on the PET micro-prismatic reflective tape substrate film layer by coating and gluing, and the step-by-step baking method is used to dry and solidify the formation. Sealing layer, where the drying time is 10 to 20 minutes, the baking temperature is set to 80°C to 130°C, and the thickness of the dry glue is 20 to 40 microns; 2) Pass the sealing layer and the pressing surface of the pet micro prism forming reflective film layer The pressure roller with carved patterns is embossed and compounded at high temperature, where the temperature of the pressure roller is 170°C to 250°C, the pressure is 3 to 5 kg, and the pressing rate is 3 to 6 meters per minute; 3) Apply the pressure-sensitive adhesive The cloth is dried after the peelable layer, and then composited with the other side of the base film layer. The production process of PET micro-prismatic reflective tape is simple, the production efficiency is high, and the product has the characteristics of high bonding performance, high weather resistance, high reflective brightness, etc., and has a long service life and a wide range of use.
