[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0023] like Figure 1 As shown, in one embodiment, a mildew-proof and moisture-proof aluminum foil paper includes: a base paper layer 1, a composite adhesive layer 2, an aluminum foil paper layer 3, a color layer 4 and a waterproof layer 5.
[0024] The base paper layer 1 is arranged at the top, the lower part of the base paper layer 1 is bonded by the composite adhesive layer 2 and the upper part of the aluminum foil layer 3, and the color layer 4 is arranged below the aluminum foil layer 3, and finally the waterproof layer 5 is covered below the color layer 4.
[0025] like Figure 1As shown, in this embodiment, the base paper layer 1 has a gram weight of 30-50 g / m2, the adhesive amount of the composite adhesive layer 2 is 1-2 g / m2, and the thickness of the aluminum foil paper layer 3 is 5.8-6.0 μm.
[0026] For example, the composite adhesive layer 22 uses water-based glue, which uses water as a solvent to reduce the emission of volatile organic compounds (VOCs) and can effectively reduce pollution to the environment. Compared with solvent-based glue, it dries faster and can provide good bonding properties. It can effectively combine aluminum foil with other materials (such as paper, plastic, metal, etc.) and maintain long-lasting bonding strength. It does not require high temperature or special processing equipment and is suitable for application in various production environments.
[0027] like Figure 1 As shown, in this embodiment, the color layer 4 includes a water absorbing layer 41 and an ink layer 42 , and the ink layer 42 is printed on the water absorbing layer 41 .
[0028] Exemplarily, the water-absorbing layer 41 is made of a water-absorbing material woven in a double-warp and double-weft weaving method. The water-absorbing material can be natural fiber (cotton fiber, linen fiber, bamboo fiber, etc.) or artificial fiber (polypropylene fiber, polyvinyl chloride fiber, polyester fiber, etc.). Artificial fiber has good hydrophobicity, and natural fiber has good moisture absorption and air permeability. Interweaving artificial fiber with natural fiber can achieve a one-way moisture conduction effect, can absorb moisture and organic matter, prevent external moisture from entering the inner layer, achieve a moisture-proof effect, and improve wear resistance, durability and antibacterial and mildew-proof effects.
[0029] Furthermore, the ink layer 42 is any one of water-based varnish, water-based matte oil and water-based color ink, and the ink amount of the color layer 4 is 1-2 g / ㎡.
[0030] like Figure 1 As shown, in this embodiment, a waterproof layer 5 is bonded below the ink layer 42 .
[0031] Exemplarily, the waterproof layer 5 is made of a hydrophobic material, which may be polyethylene (PE), polyester (PET), polyurethane (PU), etc. The thickness of the waterproof layer 5 is 1-2 μm.
[0032] Through the above technical solution, the waterproof layer 5 of the present application is made of hydrophobic material, which can prevent moisture from accumulating on the surface of the aluminum foil, thereby improving the mildew and moisture-proof performance of the aluminum foil, while reducing the wear and tear of the aluminum foil caused by the external environment; and the color layer 4 includes a water-absorbing layer 41 and an ink layer 42, which can absorb moisture and organic matter, effectively prevent the growth of bacteria, and further improve the mildew and moisture-proof performance of the aluminum foil.
[0033] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
