Detailed Description

The utility model is further described with reference to the following figures and detailed description:

as shown in fig. 1 to 3, a novel packaging sleeve for preventing oxidation of an aluminum coil comprises an aluminum coil 1 in a hollow cylinder shape, wherein composite paper 2 is arranged outside the aluminum coil 1, the composite paper 2 is wound on the aluminum coil 1 in a layer-by-layer penetrating manner, the aluminum coil 1 is completely wrapped and matched with the aluminum coil 1 in shape, and a plastic bag 3 is arranged outside the composite paper 2 for sleeving and sealing. The aluminum coil is wound in a penetrating way by using the composite paper layer by layer, so that the aluminum coil product can be completely covered and wrapped, and the first step is to isolate the external air, isolate the external contact while avoiding oxidation, avoid the friction with foreign objects and achieve the protection effect; the plastic bag is arranged outside the composite paper, and the second step isolates condensed water generated by cold and hot air alternation, thereby avoiding the problem of aluminum coil product oxidation caused by the penetration of the condensed water.

The composite paper 2 is PE film coated composite paper. The PE laminated composite paper is a paper product with one-side plastic coating treatment, and has the characteristics of oil resistance, water resistance, high bursting strength, difficult tearing, good moisture resistance and the like.

The inner diameter of the aluminum coil is more than 300mm, and the width of the composite paper 2 is 100-300 mm. When the inner diameter of the aluminum coil is 300-600 mm, the width of the composite paper is 100 mm; when the inner diameter of the aluminum coil is 600-1000 mm, the width of the composite paper is 200 mm; when the inner diameter of the aluminum coil is 1000-2000 mm, the width of the composite paper is 300 mm; the inner diameter of the aluminum coil is not easy to be too small, the winding of the coil-shaped composite paper is easy to be influenced if the inner diameter is too small, the full-coverage effect is not easy to achieve, and meanwhile, the drying agent placed in the aluminum coil is also influenced, so that the transportation and the fixation of the aluminum coil are inconvenient; the width of the composite paper is 100-300 mm, so that the composite paper is convenient to wind and can reduce waste.

An outer packing bag 6 is arranged outside the plastic bag 3. Set up terminal surface confined outer packing bag outside, the packing shaping not only conveniently distinguishes different models, also can avoid in the transportation rainwater to invade inside the aluminium book, prevents the plastic bag damage simultaneously, influences the effect of isolated cold and hot air produced comdenstion water in turn, reaches duplicate protection's effect, and the effect is better.

The drying agent 5 is fixed in the aluminum roll 1, and the drying agent 5 is positioned between the aluminum roll 1 and the composite paper 2. The drying agent is placed in the aluminum coil to absorb damp gas from the inside, so that the phenomenon that the cold and hot air in the package convects along with the rise of the surface temperature of a product in the process of transporting from an area with low air temperature to an area with high air temperature and high humidity is avoided, and the product loss caused by the oxidation of the aluminum coil product is prevented.

Specifically, in this embodiment, the inside of the aluminum roll must be left empty, so that the inner diameter of the aluminum roll is over 300mm, which is convenient for the PE laminated composite paper to be wound and packaged; the size and width of the PE laminating composite paper roll can be determined according to the inner diameter of the aluminum roll, and the PE laminating composite paper roll is divided into coiled materials of 100-300 mm for winding.
