[0015] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0016] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0017] like Figure 1As shown, a specific embodiment of the utility model provides a thin-sheet packaging box, which has a small molding thickness for packaging bags, and specifically includes a packaging board body 100, wherein the packaging board body 100 is provided with a fold mark along the middle part, and packaging side panels 110 are formed on both sides of the packaging board body 100 corresponding to the fold mark, wherein one packaging side panel 110 is provided with adhesive sheets 120 on both sides, and the other packaging side panel 110 is provided with adhesive surfaces that can be adhered to the adhesive sheets 120 on both sides; and one packaging side panel 110 is provided with a sealing sheet 130 at one end away from the other packaging side panel 110, and the sealing sheet 130 can be adhered to the outer side surface of the end of the other packaging side panel 110.

[0018] like Figure 1 As shown, through the above-mentioned arrangement, the packaging bag in this embodiment adopts an ultra-thin packaging structure, that is, a packaging space is formed by folding the packaging board body 100, and sheet products to be packaged, such as envelopes, sheet objects, etc., can be placed between the packaging side panels 110; the packaging side panels 110 are adhered to each other by adhesive sheets 120 to improve packaging stability; in addition, the packaging bag formed by the packaging side panels 110 can also be sealed by a sealing sheet 130 to achieve sealed packaging; the packaging bag formed in the folded form in this embodiment has a smaller molding height and higher compressive strength; no additional tape packaging is required, which improves packaging convenience.

[0019] like Figure 1 As shown, in order to improve the stability of the packaging side panel 110 after being folded, a first adhesive layer 200 is provided on the outer side of the adhesive sheet 120 in this embodiment. The adhesive sheet 120 can be firmly attached to the adhesive surface through the first adhesive layer, so that the two sides of the packaging bag are not easily deformed and damaged; at the same time, a second adhesive layer 300 is provided on the inner side of the sealing sheet 130 in this embodiment, and a removable release paper layer is attached to the surface of the second adhesive layer 300. The second adhesive layer 300 can be used to seal the opening of the sealing sheet 130. When sealing, the release paper layer can be torn off to perform the sealing operation. In actual application, the first adhesive layer 200 and the second adhesive layer 300 adopt a 3M double-sided adhesive structure.

[0020] like Figure 1 As shown, in order to prevent the sealing sheet 130 from scratching the operator during the sealing package, the corners of the sealing sheet 130 at both ends are rounded in this embodiment. After the rounded corners are processed, the sealing operation is safer. In addition, a sealing fold 140 is provided at one end of the sealing sheet 130 connected to the packaging side panel 110; the sealing fold 140 makes it easier to bend the sealing sheet 130 and stick it on the outer surface of the packaging side panel 110.

[0021] In production applications, the packaging board body 100 is formed by cutting corrugated cardboard. The corrugated cardboard structure is easy to obtain materials, has high structural strength, and has good anti-deformation effect after packaging molding.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
