                  The working principle of reflective film

                  Reflective film is an optical material with high reflection characteristics, which can reflect light to a specified direction, thereby reducing the loss of light energy. At present, there are mainly two types of reflective films on the market, one is a metal reflective film, and the other is a dielectric reflective film. The metal reflective film is made of metal materials, such as silver, aluminum, etc., and is generally used in products such as mirrors and reflectors. The dielectric reflective film is made of a dielectric material, and its optical properties are different from those of the metal reflective film.

                  The difference between BOPP precoated film and PET precoated film

                  Pre-coating refers to the process of pre-gluing and rewinding the plastic film and then compounding it with the paper printing. It is first coated on the film by the pre-coated film processing plant according to the specifications and format, and then rewound for the use of manufacturers to choose, and then combined with printed matter.
