Abstract
The utility model relates to a dustproof and ventilated preservative packaging film and belongs to the technical field of packaging films. The dustproof and ventilated preservative packaging film comprises an imporous ventilated film layer; a ventilated film layer is arranged on the upper surface of the imporous ventilated film layer by hot pressing or dry compounding; and a thermally sealed film layer is arranged on the lower surface of the imporous ventilated film layer by hot pressing or dry compounding. The dustproof and ventilated preservative packaging film is simple in structure, reasonable in design, flat in appearance and low in cost; a surface layer adopts a ventilated film layer; as the surface layer and a bottom layer are both provided with vent holes, the air permeability is good; and as the imporous ventilated film layer is arranged in the middle, power does not leak, the dustproof effect is well achieved.
