Description

Technical Field

[0001] This utility model relates to the field of corrugated paper technology, specifically to a wear-resistant, waterproof, double-layer paper core environmentally friendly corrugated paper structure. Background Technology

[0002] Corrugated cardboard is a common packaging material used for the outer packaging of various items such as metal machinery, wood, plastic products, ceramics, and electrical appliances. It can provide a certain degree of protection. Common corrugated cardboard has a simple structure and relatively low resistance to pressure and water. It is easily damaged when subjected to greater external pressure, which can damage or even deform the contents inside.

[0003] For example, Chinese Patent (Announcement No.: CN216466716U) discloses a double-sided, double-core environmentally friendly corrugated cardboard, comprising an outer paper layer. The outer paper layer is connected to the upper end of a longitudinal corrugated core. The bottom end of the longitudinal corrugated core is connected to one end of a middle paper layer. The other end of the middle paper layer is connected to the upper end of a transverse corrugated core. The bottom end of the transverse corrugated core is connected to an inner paper layer. Both the longitudinal and transverse corrugated cores are made of double-layer V-shaped corrugated paper composites bonded together. The corrugation lines of the longitudinal and transverse corrugated cores are perpendicular to each other. The outer paper layer is bonded to the longitudinal corrugated core, the longitudinal corrugated core to the middle paper layer, the middle paper layer to the transverse corrugated core, and the transverse corrugated core to the inner paper layer by adhesive. This makes the overall structure of the utility model tight and stable, enhancing its compressive strength. The surface of the outer paper layer is provided with a waterproof curved surface layer, and a drainage pipe is provided in the recess of the waterproof curved surface layer to drain accumulated water.

[0004] This patent improves waterproofing by installing drainage pipes in the waterproof curved layer to drain accumulated water. However, the accumulated water can easily enter the interior of the corrugated paper and corrode it, which is not conducive to the long-term use of the corrugated paper. Therefore, a wear-resistant, waterproof, double-layer paper core environmentally friendly corrugated paper structure is proposed to solve the above-mentioned problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 The wear-resistant and waterproof double-layer paper core environmentally friendly corrugated paper structure in this embodiment includes a wear-resistant surface layer 1 with a thickness of 0.3mm. A structural body is fixed on the top of the wear-resistant surface layer 1, and a moisture-proof bottom layer 5 is fixed on the top of the structural body.

[0032] It is understandable that the wear-resistant surface layer 1 provides initial protection and waterproofing for the outer side of the overall structure, which helps improve the stability and waterproofing of the overall structure. The moisture-proof bottom layer 5 improves the moisture resistance of the overall structure, thereby enhancing the overall structural performance.

[0033] It is also understood that the main structure includes a first paper core layer 2, a waterproof intermediate layer 3, and a second paper core layer 4. The first paper core layer 2 is fixed to the top of the wear-resistant surface layer 1. The corrugation height of the first paper core layer 2 is 7mm, and the wear-resistant surface layer 1 is high-strength kraft paper.

[0034] The use of kraft paper makes the overall structure more robust than ordinary boxboard, with extremely high compressive strength, puncture resistance, and folding endurance. It also features good moisture resistance and appearance quality, thus improving the overall performance of corrugated paper.

[0035] It should be noted that the first paper core layer 2 is E-type corrugated paper, the waterproof intermediate layer 3 is fixed to the top of the first paper core layer 2, the second paper core layer 4 is fixed to the top of the waterproof intermediate layer 3, the second paper core layer 4 is fixed to the bottom of the moisture-proof bottom layer 5, the second paper core layer 4 is F-type corrugated paper, and the corrugation height of the second paper core layer 4 is 4.8mm.

[0036] It should also be noted that the three-layer waterproof effect is achieved by setting the first paper core layer 2, the waterproof intermediate layer 3, and the second paper core layer 4, which is conducive to improving the overall waterproof performance. The moisture-proof bottom layer 5 is conducive to absorbing moisture inside the box and isolating moisture outside the box, thus improving the waterproof and moisture-proof effect and enhancing the overall performance.

[0037] Please see Figure 2 To improve structural stability, the waterproof intermediate layer 3 in this embodiment includes a waterproof layer body 301, a connecting block 302, an outer plate 303, and an inner plate 304. The upper and lower sides of the waterproof layer body 301 are fixed to the second paper core layer 4 and the first paper core layer 2, respectively. The connecting block 302 is fixed to the waterproof layer body 301. The thickness of the waterproof layer body 301 is 0.05mm, and the waterproof layer body 301 is a PE film.

[0038] PE film has the advantages of moisture resistance and low moisture permeability. By using PE material, the overall waterproof performance of the structure can be improved. The connection between the waterproof layer 301 and the second paper core layer 4 and the first paper core layer 2 is strengthened by fixing the outer plate 303 and the inner plate 304 with the connecting block 302, which helps to improve the stability of the overall structure and enhance the overall performance.

[0039] As can be seen, the waterproof layer 301 has an installation hole on its inner side, the connecting block 302 is fixed to the waterproof layer 301 through the installation hole, the outer plate 303 is fixed to the bottom of the connecting block 302, the inner plate 304 is fixed to the top of the connecting block 302, the inner plate 304 is located inside the second paper core layer 4, and the outer plate 303 is located inside the first paper core layer 2.

[0040] In this embodiment, the installation holes facilitate the fixing of the connecting block 302 and the waterproof layer 301, thereby improving the overall structural stability and enhancing the overall performance of the corrugated paper. The waterproof layer 301 further improves the waterproof performance of the structure, thus enhancing the overall structural performance.

[0041] Please see Figures 3 to 4 To improve the overall convenience of using corrugated paper, the moisture-proof bottom layer 5 in this embodiment includes a moisture-proof layer 501, an adhesive strip 502, and an insert block 503. The moisture-proof layer 501 is fixed to the top of the second paper core layer 4. The thickness of the moisture-proof layer 501 is 0.4mm. Multiple drying blocks are fixed on the inner side of the moisture-proof layer 501. The moisture-proof layer 501 is made of waterproof kraft paper, and each drying block has a drying hole.

[0042] It can also be seen that the combination of drying blocks and drying holes can effectively dry the air inside the box, thereby ensuring the stability of the items stored inside and further improving the overall performance of the corrugated paper structure.

[0043] It should be noted that both the adhesive strip 502 and the insert block 503 are fixed to the top of the moisture-proof layer 501. The top of the moisture-proof layer 501 has an insertion interface extending to its inner side, and the insert block 503 is adapted to the insertion interface.

[0044] In this embodiment, the insertion of the insert block 503 and the insertion interface facilitates the initial fixed connection between different corrugated cardboards. The adhesive strip 502 is used to bond different corrugated cards, which facilitates the assembly of the box structure, thereby improving the production efficiency of the finished product and enhancing the performance of the corrugated cardboard structure.

[0045] The working principle of the above embodiments is as follows:

[0046] When water molecules attempt to penetrate this double-layered, environmentally friendly corrugated paper structure, they first encounter the wear-resistant surface layer 1. Although this kraft paper layer has some water absorption, its dense surface initially blocks most of the water from entering. Subsequently, if the water molecules continue to penetrate, they will encounter the waterproof layer 301, which is a PE film. This layer almost completely prevents further diffusion of water. Even if a small amount of water penetrates the PE film to reach the second paper core layer 4, this layer also has good waterproof performance. In addition, the adjacent moisture-proof layer 501 provides a final line of defense. Through the arrangement of the outer board 303 and the inner board 304, the water is effectively protected. The second paper core layer 4 and the first paper core layer 2 on the upper and lower sides are reinforced with the waterproof layer 301, which improves the overall stability of use. The adhesive strip 502 facilitates the adhesion between different corrugated papers. The insertion of the insert block 503 and the insertion interface facilitates the locking of different corrugated papers and the initial installation of different corrugated papers. The combination of the drying block and the drying hole dries the moisture inside the carton. In the whole process, the double-layer paper core design not only increases the overall strength of the carton, but also improves its resistance to external impacts, making it particularly suitable for the protection of goods in long-distance transportation and in harsh weather conditions.
