High-barrier co-extrusion stretch film

The utility model discloses a high-barrier co-extrusion stretch film and relates to the technical field of co-extrusion stretch films. The stretch film comprises a stretch film body, the stretch film body sequentially comprises an antibacterial layer, a first waterproof layer, a heat insulation layer, a second waterproof layer, a flame-retardant layer and an anti-aging layer from bottom to top, and the antibacterial layer, the first waterproof layer, the heat insulation layer, the second waterproof layer, the flame-retardant layer and the anti-aging layer are bonded with one another. The flame-retardant mechanism is arranged on the flame-retardant layer and is used for retarding flame of the stretching film main body, and the wear-resistant mechanism is arranged on the anti-aging layer and is used for increasing the wear resistance. By arranging the flame-retardant mechanism, the flame-retardant performance of the stretch film main body can be greatly enhanced, meanwhile, by arranging the wear-resistant mecha
