Reflective tape test method

The working principle of reflective tape is based on the law of reflection of light, that is, at what angle the light is emitted from, it will be reflected back at what angle. Therefore, to observe the reflective effect of reflective tape, stand at the same angle as the light source. In the case of the same angle, the reflective effect is the strongest and most obvious. If you observe from other angles, the reflective effect will be poor. So if you purchase reflective tape samples from other companies, you can test the reflective effect according to the following methods.

The first method is to stand at a place more than three meters away from the reflective tape in a dark environment, turn on the flash of the mobile phone to take a photo, and you can see the obvious reflective effect in the picture taken. Method two is also in a dark environment, turn on the flashlight at a distance of more than three meters from the reflective tape, place the flashlight between the nose and eyes, and the light is basically at the same angle as the line of sight, and the obvious reflective effect can be seen. The stronger the light of the flashlight, the better the reflection effect. Method three needs to be outdoors at night. At a distance of more than 20 meters from the reflective tape, sit in the cab and illuminate the reflective tape with the car lights to test the reflective effect.

Only the correct test method can measure the definite reflective effect, if the test method is wrong, the reflective effect may not be visible. The reflective tape of Kunshan Yuhuan Package Material Co., Ltd. will have strict quality inspection procedures before leaving the factory.
