High-strength insulating film

The utility model relates to the technical field of films, in particular to a high-strength insulating film which comprises a shading film, an insulating layer and a reinforcing layer. The number of the insulating layers is two, the reinforcing layer is located between the two insulating layers, the number of the shading films is two, and the two shading films are connected to the outer surfaces of the two insulating layers respectively. A netted groove is formed in the surface of the insulating layer, and the section of the groove is in an inverted trapezoid shape. In conclusion, the beneficial effects of the utility model are that the insulating layer of the film can guarantee good insulation protection of articles wrapped by the insulating layer, and the reinforcing layer can form a fixed shape after being irradiated by ultraviolet rays, so that the strength is greatly improved, and the film can be prevented from being torn in a product transportation process; the fiber net shrinksand curls after being hea
