[Abstract] The utility model relates to a packaging material, in particular to a nano composite packaging material. Including the base layer, nano-metal layer, a fiber layer is added between the base layer and the nano-metal layer, and the three layers are respectively integrated by a bonding layer. The fibrous layer may be carbon fiber, vegetable fiber or nylon filament. The base layer may be a plastic or paper or polyester sheet (PET), and the metal layer is a nano aluminum foil layer or a nano silver layer. Compared with the existing packaging materials, it greatly increases the antibacterial, tensile, moisture resistance, impact resistance, puncture resistance, oil resistance, acid and alkali resistance, and can be used for internal and external packaging of foods, beverages, medicines, cigarettes, etc. . At the same time, the use of nano-aluminum foil, silver or polyethylene layer, effectively reducing the water vapor transmission coefficient and the amount of penetration, can extend the shelf life of food and medicine.
