[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-5 A high-strength cellulose nanofiber material packaging carton includes a bottom cover plate 8. Bottom fastening holes 7 are respectively opened on both sides of the bottom surface of the bottom cover plate 8. A front panel 1, a back support plate 5, and side sealing plates 6 are respectively provided on the vertical perimeter of the bottom cover plate 8. Side fastening plates 2 are connected to the ends of both side sealing plates 6. The side fastening plates 2 and 6 are folded 180° in their formed state, and the gap between the side fastening plates 2 and 6 in their formed state is 0.8-1.1 times the thickness of the board material. A protrusion is provided at the bottom of the side fastening plate 2, and the protrusion cooperates with the bottom fastening holes 7. Side sealing plates 4 are respectively provided on both sides of the back support plate 5. A bent cover plate 3 is provided on the top of the back support plate 5. A bending plate 9 is provided at the connection point between the back support plate 5 and the bent cover plate 3. An auxiliary buckle 10 is provided on the side of the bent cover plate 3. Corresponding through holes are opened on the side sealing plates 4 at the corresponding positions of the auxiliary buckles 10 in the vertical state of the bent cover plate 3.

[0027] When transporting, the bending cover 3 is bent at 90°. It should be noted that the internal product's height is matched with the height of the back support plate 5. After transportation, when the product is sold by the distributor, the bending cover 3 is flipped to a vertical position, and the auxiliary buckle 10 on the back is engaged in the corresponding hole in the back support plate 5, thus ensuring that the bending cover 3 is completely vertical. When used for sales, corresponding promotional patterns, including but not limited to the company logo, sales price, etc., can be printed on the surface of the bending cover 3. The printing can be done according to the actual situation, so that the entire packaging box can not only be used as a transport box, but also as a sales display shelf. When stacking a small amount, it can also be used as a simple shelf, further reducing the economic costs of the seller and increasing sales enthusiasm.

[0028] In the thin sheet state after production, using the bottom cover plate 8 as the reference plane, flip the side sealing plates 6, front panel 1, and back support plate 5 upwards by 90°. After the flipping is completed, see the attached diagram. Figure 1 The panels on both sides of the front panel 1 and part of the side sealing panel 4 are inserted into the inside of the side sealing panel 6. Then the side buckle panel 2 is bent 180° and the end is inserted into the bottom buckle hole 7 to complete the forming of the entire box. Specific Implementation Example 2:

[0030] Based on the technical solution of Specific Embodiment 1, the following technical improvements and adjustments can be made further:

[0031] While maintaining the original high-strength cellulose nanofiber material, the board material undergoes an appropriate addition of polymer adhesives or bio-based resin impregnation processes to its fiber phase structure. This allows the board to maintain good deformation recovery and durability under humid, high-temperature, and long-distance transportation conditions. Furthermore, a thin, breathable, waterproof, and oleophobic coating is added to the surface of the board to improve the stability of the carton in various storage and transportation environments, ensuring the preservation of the carton's shape and printed patterns during sales. Specific Implementation Example 3:

[0033] Based on the technical solution of Specific Embodiment 1, the following technical improvements and adjustments can be made further:

[0034] In addition to the existing side snap-fit ​​panels and bottom snap-fit ​​holes, a set of small directional snaps or clamping structures are appropriately added at the joint between the bottom plate and the side snap-fit ​​panels to prevent the carton from becoming loose when the lid is bent vertically. Simultaneously, small guide grooves or recesses aligned with the auxiliary snap-fit ​​positions are added to the side sealing panels on both sides of the back support plate, making it easier for the bent lid to align and lock securely when vertically flipped. While maintaining the original gap standard (0.8-1.1 times the board thickness), the forming accuracy of the side snap-fit ​​panels and side sealing panels is improved through enhanced die-cutting processes, resulting in higher consistency and lower fitting errors in the carton structure during folding and flipping.

[0035] In addition to the printed surface of the bent cover, corresponding areas are reserved on the back support plate or side seal plate to create miniature information windows or slots using a die-cutting process. These are used to place replacement labels or price tags, allowing dealers to easily update product information. If needed, a lightweight, erasable film can be added to the inside of the bent cover plate to record temporary promotional information or store instruction documents. Furthermore, small holes for hooks or hanging strips are also provided on the side seal plate or front panel, allowing the carton to hold small accessories or promotional materials when in sale, increasing the versatility of the display.

[0036] In summary:

[0037] 1. By bending the cover plate 3 90° to match the internal product dimensions during transportation, the box can not only meet the requirements of stable stacking and protection during transportation, but also flip the cover plate 3 into a vertical state when the distributor sells it. The auxiliary buckle 10 is inserted into the through hole on the side sealing plate 4 to make the cover plate 3 stand up completely, thus instantly transforming it into a simple shelf with display function, reducing the purchase and use costs of additional display props.

[0038] 2. The printing treatment on the surface of the bent cover plate 3 provides distributors with direct brand exposure and price labeling space in the sales scenario. Without the need for additional packaging and promotional materials, it can achieve rapid deployment and information communication, enhance consumers' awareness of products and brands, and thus help improve sales efficiency and enthusiasm.
