[0002] In the field of food packaging technology, traditional solid foods such as pastries and candies generally adopt top-and-bottom lid, drawer-type, or folding cardboard box structures. Their sealing methods mainly rely on passive fixing methods such as tongues, magnetic closures, or hook and loop fasteners. While these structures are widely used, they suffer from core defects such as insufficient sealing pressure after sealing and easy loosening of the structure due to repeated opening and closing, directly affecting the long-term sealing performance of the packaging and the preservation effect of the contents. Specifically, traditional packaging is prone to problems such as tongue deformation, weakened magnetic force, or hook and loop failure after repeated opening, causing the sealed parts to fail to return to their initial tight state. This not only reduces the secondary sealing performance of the packaging but also accelerates food moisture absorption, oxidation, and flavor loss, making it difficult to meet consumers' increasingly demanding requirements for food preservation.

The upper adhesive surface 341 is folded and connected to the upper wallpaper board surface 336 of the first packaging folding cardboard piece 330. The upper adhesive surface 341 is glued to the inner wall of the upper wallpaper panel 336 of the last packaged folded cardboard piece 330, the slit adhesive surface 342 is glued to the inner wall of the slit cardboard panel 334 of the last packaged folded cardboard piece 330, and the lower adhesive surface 343 is glued to the inner wall of the lower wallpaper panel 332 of the last packaged folded cardboard piece 330. This application cleverly connects the unfolded cardboard strips end to end by bonding the folded cardboard piece 340 to the inside of the last folded cardboard piece 330, forming a closed cylindrical box body. This ensures the structural integrity and sealing foundation of the packaging box body 100. In addition, the three bonding surfaces of the folded cardboard piece 340—the upper bonding surface 341, the slit bonding surface 342, and the lower bonding surface 343—are bonded to the corresponding inner walls of the last cardboard piece, forming a large bonding area. This significantly enhances the connection strength at the box body closure and prevents cracking at that point.

[0032] The lower wallpaper panel 332 and lower adhesive surface 343 of a plurality of sequentially folded and connected packaging folding cardboard pieces 330 are joined to form a plurality of lower side walls 120 of the packaging box body 100. A pair of adjacent slit cardboard panels 334 between the plurality of sequentially folded and connected packaging folding cardboard pieces 330 form the slit opening 140. The middle wallpaper panel 333, slit cardboard panel 334 and slit adhesive surface 342 of a plurality of sequentially folded and connected packaging folding cardboard pieces 330 are joined to form a plurality of middle side walls 130 and a plurality of slit openings 140 of the packaging box body 100.

The packaging bottom cardboard 310 is the bottom wall 110 of the packaging box body 100.

[0033] The bionic strapping 200 is one or more strips. The bionic strapping 200 has a free end. The free end of the bionic strapping 200 passes around the connection of the several middle sidewalls 130 and the several upper sidewalls 150 and is knotted to fix and tighten the top opening of the packaging body. The free end of the bionic strapping 200 is inserted into the slit latch 140 and pulled tight to fix it. This is a simple, effective and reliable mechanical fixing method. It is easy to operate and can achieve quick opening and closing. The upper sidewalls 150 of the packaging box 100 are secured and tightened by the biomimetic strapping 200, forming a group of protruding branches with outwardly extending wings. The biomimetic strapping 200 wraps around and tightens the wings to form a fan-shaped or trumpet-shaped constriction structure. This application tightens the upper sidewalls 150 with the biomimetic strapping 200 to form a group of protruding branches with outwardly extending wings, ultimately presenting a fan-shaped or trumpet-shaped constriction structure. This is not only visually novel and unique, imitating natural forms such as flower buds and fruit stems, enhancing the packaging's aesthetic appeal and brand recognition, but the constriction structure itself also has a certain anti-loosening function.

[0034] The packaging box 100 is shaped like a truncated frustum or prism, wider at the bottom and narrower at the top. This frustum or prism structure lowers the center of gravity, making it more stable. This shape also facilitates stacking and transporting multiple boxes, saving space. The cross-sectional shape of the packaging box 100 is polygonal, such as hexagonal or octagonal, which is more aesthetically pleasing and design-oriented than a simple quadrilateral, while also providing a better grip. In this embodiment, the polygon is hexagonal. Figure 1 , Figure 2 and Figure 3 As shown, hexagons or octagons are visually softer and more refined. The knotting method is a bow. Using a bow greatly enhances the decorative and gift-like qualities of the packaging, making it look more beautiful and upscale, which helps to improve the brand image. In addition, a bow is a common and easy-to-untie knot, making it convenient for consumers to open and reseal the packaging.

[0035] The food packaging box is also equipped with a magnetic buckle, which includes a magnet and a metal sheet. The magnet is set on the packaging box body 100, and the metal sheet is set on the bionic strapping 200. In addition to mechanical strapping, magnetic adsorption provides extra fixing force for packaging sealing, preventing the bionic strapping 200 from accidentally loosening and improving the reliability of the seal. Furthermore, the magnetic buckle can achieve accurate positioning and adsorption with a click, providing a better user experience, especially suitable for scenarios requiring frequent opening and closing or those seeking ultimate convenience and sealing.

[0036] The biomimetic strapping 200 is made of food-grade kraft paper, composite materials, or biodegradable polymers. The packaging box 100 is made of biodegradable pulp molding or food-grade cardboard. The use of materials such as food-grade kraft paper, biodegradable polymers, and biodegradable pulp molding emphasizes the environmental friendliness and food safety of this packaging solution, meeting current consumer demands and regulatory requirements for green packaging. The inner wall of the packaging box 100 is covered with a food-grade coating or aluminum foil, which directly improves the barrier properties of the packaging, such as moisture resistance, oil resistance, and gas resistance, thus enhancing the preservation effect.
