[0024] See also Figure 1-6 , the technical solution provided by this embodiment is as follows:

[0025] A moisture-proof boxboard comprises a supporting base 1 and a cardboard box 2. The cardboard box 2 comprises a reinforcing paper layer 201, a resin waterproof film 202 and an outer coating 203. The reinforcing paper layer 201 is embedded in the inner cavity around the cardboard box 2, the resin waterproof film 202 is pasted on the outer surface of the reinforcing paper layer 201, the outer coating 203 is coated on the outer surface of the cardboard box 2, and the bottom of the cardboard box 2 is bonded to the inner cavity at the top of the supporting base 1 by waterproof glue.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 6The reinforcing paper layer 201 includes a reinforcing material 201a and an isolation coating 201b, the reinforcing material 201a is pasted on the outer surface of the reinforcing paper layer 201, and the isolation coating 201b is respectively coated on the outer surface of the reinforcing material 201a and the inner surface of the reinforcing paper layer 201, and the left and right sides of the bottom of the inner cavity of the cardboard box 2 are fixedly installed with a first slot seat 16, the top of the first slot seat 16 is provided with a first card slot 17, and the inner cavity of the first card slot 17 is provided with a first hollow structure cardboard 12, and the front and back sides of the bottom of the inner cavity of the cardboard box 2 are fixedly installed with a second slot seat 18, the top of the second slot seat 18 is provided with a second card slot 19, and the inner cavity of the second card slot 19 is provided with a second hollow structure cardboard 14, and the bottom of the inner cavity of the supporting base 1 is fixedly installed with a corrugated cardboard 8, the surface of the corrugated cardboard 8 is bonded with a corrugated paper strip 9, the top of the corrugated cardboard 8 is bonded with a concave-convex cardboard 10, and the top of the concave-convex cardboard 10 is provided with a convex strip 11.

[0027] Specifically, the reinforcing paper layer 201 can increase the overall strength and rigidity of the cardboard box 2, making it more resistant to compression and bending, thereby improving the stability of the packaging. A reinforcing material 201a is added to the reinforcing paper layer 201, and the reinforcing material 201a is cellulose fiber. These materials can increase the strength and stability of the reinforcing paper layer 201, and improve the durability of the overall packaging. In addition, by setting an isolation coating 201b, the isolation coating 201b adopts a water-soluble resin coating, which can increase the moisture resistance and water resistance of the cardboard box 2, and improve the durability of the overall packaging. The first groove seat 16 and the second groove seat 18 located at the bottom of the inner cavity of the cardboard box 2 can effectively support the inner cavity of the cardboard box 2, and at the same time, the first groove seat 16 and the second groove seat 18 at the bottom of the inner cavity of the cardboard box 2 can effectively support the inner cavity of the cardboard box 2. A hollow structure cardboard 12 and a second hollow structure cardboard 14 are formed by alternately stacking multiple layers of cardboard. The hollow structure in the middle can provide a better vibration reduction effect, which can effectively reduce the impact force from propagating to the inside, thereby protecting the packaged items. The corrugated cardboard 8 added to the inside of the support base 1 is composed of a layer of corrugated paper sandwiched between two layers of kraft paper. This structure gives the corrugated cardboard 8 a high compressive resistance and strength, ensuring that the support base 1 can support and stabilize the bottom of the cardboard box. The concave-convex cardboard 10 forms a series of small concave and convex on the surface through the convex strips 11. This design can increase the flexibility and elasticity of the corrugated cardboard 8, thereby providing a better vibration reduction effect. Example

[0028] See also Figure 1 , Figure 3 and Figure 5Inner corner support strips 13 are fixedly installed around the inner cavity of the cardboard box 2, supporting protection strips 7 are fixedly installed around the outer surface of the cardboard box 2, insulation paper sheets 15 are inserted on the front and back sides of the inner cavity of the cardboard box 2, plastic corner sleeves 6 are fixedly installed around the support base 1, and vibration-damping gaskets 5 are bonded to the front and back sides and the left and right sides of the support base 1. The top of the cardboard box 2 is connected to the box cover 3 by a flanging type, and paper corner sleeves 4 are bonded around the box cover 3. A sealing sheet 20 is fixedly installed on the bottom of the box cover 3.

[0029] Specifically, the inner corner support strips 13 can provide support on all sides of the inner cavity of the cardboard box 2, the support protection strips 7 can provide support and protection on all sides of the outer side of the cardboard box 2, the insulation paper sheets 15 can isolate the external temperature to a certain extent, the plastic corner sleeves 6 can protect all sides of the support base 1, the box cover 3 can be directly installed on the top of the cardboard box 2 by a flanging connection method, and the sealing sheet 20 can seal the joint between the box cover 3 and the cardboard box 2.

[0030] Working principle: The reinforced paper layer 201 can increase the overall strength and rigidity of the cardboard box 2, making it more resistant to compression and bending. Reinforcement material 201a is added to the reinforced paper layer 201. The reinforcing material 201a is cellulose fiber. These materials can increase the strength and stability of the reinforced paper layer 201 and improve the durability of the overall packaging. By setting an isolation coating 201b, the isolation coating 201b adopts a water-soluble resin coating. This coating can increase the moisture resistance and water resistance of the cardboard box 2 and improve the durability of the overall packaging. The first groove seat 16 and the second groove seat 18 located at the bottom of the inner cavity of the cardboard box 2 can effectively support the inner cavity of the cardboard box 2. At the same time, the first hollow structure cardboard 12 and the second hollow structure cardboard 14 are formed by alternating multiple layers of cardboard, and the hollow structure in the middle can provide a better vibration reduction effect, which can effectively reduce the impact force from propagating to the inside, thereby protecting the packaged objects. The product is a corrugated cardboard 8 added to the inside of the support base 1. The corrugated cardboard 8 is composed of a layer of corrugated paper sandwiched between two layers of kraft paper. This structure gives the corrugated cardboard 8 high compressive resistance and strength, ensuring that the support base 1 can support and stabilize the bottom of the cardboard box. The concave-convex cardboard 10 forms a series of small concave and convex on the surface through the convex strips 11. This design can increase the flexibility and elasticity of the corrugated paper 8, thereby providing a better vibration reduction effect. The inner corner support strip 13 can support the inner cavity of the cardboard box 2 around, the support protection strip 7 can support and protect the outer side of the cardboard box 2 around, the insulation paper 15 can isolate the external temperature to a certain extent, the plastic corner sleeve 6 can protect the surrounding of the support base 1, and the box cover 3 can be directly installed on the top of the cardboard box 2 through a flanging connection method, and the sealing sheet 20 can seal the joint between the box cover 3 and the cardboard box 2.

[0031] In summary: the moisture-proof boxboard can increase the overall strength and rigidity of the cardboard box 2 by strengthening the paper layer 201, making it more resistant to pressure and bending, thereby improving the stability of the packaging; a layer of resin waterproof film 202 is attached to the outer surface of the strengthened paper layer 201, and this film layer can effectively block the penetration of humid gases and liquids, and provide additional moisture-proof protection for the cardboard box 2; reinforcing material 201a is added to the strengthened paper layer 201, and the reinforcing material 201a is cellulose fiber. These materials can increase the strength and stability of the strengthened paper layer 201, and improve the durability of the overall packaging; by adding the strengthened paper layer 201, the resin waterproof film 202 and the reinforcing material 201a to improve the structure and paper layer of the cardboard box 2, the durability and stability of the overall packaging can be significantly improved, and the product can be protected from the influence of the humid environment, which solves the problem that the durability and stability of the current moisture-proof boxboard overall packaging are poor, resulting in deformation and damage when the product is packaged and transported, and it is not easy to store for a long time, thus affecting the safe transportation and storage of the product.
