*Reduce consumption: the loss of cold energy can be compensated by pasting the heat insulation film, which can instantly reduce the temperature inside the car and save fuel consumption to a certain extent;. *UV protection: The medium and long waves of ultraviolet rays can penetrate thick glass, and most ultraviolet rays can be blocked by pasting a layer of heat insulation film to prevent skin damage and reduce the aging of car interiors;. * Heat insulation and sun protection: the film can also block the heat generated by infrared rays, and also block the damage caused by ultraviolet rays to the skin and auto parts. *Safety and explosion-proof: it can improve the safety of the car, and the adhesive layer of the film can reduce the damage to passengers after the glass is broken;. * Increase privacy space: Because the car film is generally able to see the outside of the car clearly from the inside of the car, but not the inside of the car from the outside, so a good private space is left for the car;.
