The utility model relates to the technical field of packaging films, in particular to a double-layer bubble heat insulation film which comprises a lower layer, a bubble layer, an upper layer and a protective layer, the bubble layer is arranged between the lower layer and the upper layer, the upper layer is connected with the lower layer through the bubble layer, the protective layer comprises a wear-resistant layer and an anti-static layer, and the wear-resistant layer is arranged between the upper layer and the lower layer. The wear-resistant layer is arranged on the upper layer and located on the side, away from the bubble layer, of the upper layer, the anti-static coating is coated on the wear-resistant layer and located on the side, away from the upper layer, of the wear-resistant layer, and the problems that due to the fact that extrusion and collision occur when express packages are sorted, a heat insulation bubble film is damaged, and the service life of the express packages is prolonged are solved.
