AI Technical Summary
The existing packaging bag sealing method is easy to be re-opened, and the heating method is difficult to leave traces of unopened, which is insufficient safety.
The sealant layer design is adopted, including sealant layer 1, release layer and anti-destruction mark. The anti-destruction mark is pasted on the sealing surface by the sealant layer 2, and combined with the local heating bond of the hot melt adhesive layer, an irreversible seal is formed.
It has achieved obvious traces left after unpacking, improved the safety of packaging bags, simplified the production process, and improved efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of packaging bags, in particular to an anti-theft file folded opening packaging bag. Background Art
[0002] When the existing packaging bags are in use, most of them are sealed at the bag body sealing part by means of thumbtacks or gluing. After the thumbtacks are removed, they can be resealed. When gluing and sealing, it can be opened without leaving a trace through a special heating method, which is not safe enough. Therefore, the technical personnel in this field provide an anti-theft file folded opening packaging bag to solve the problems raised in the above background art. Content of the Utility Model
[0003] The purpose of the utility model is to provide an anti-theft file folded opening packaging bag to solve the problems raised in the above background art.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] An anti-theft file folded opening packaging bag includes a bag body and a folded opening sealing body arranged at the top of the bag body. The bag body and the folded opening sealing body are bonded through a provided sealing glue layer. The sealing glue layer includes a first sealing glue layer, a plurality of release layers arranged at equal intervals in the middle area of the first sealing glue layer, anti-disassembly marks arranged on the upper and lower surfaces of the release layers, and a second sealing glue layer arranged on the surfaces of the anti-disassembly marks.
[0006] As a further scheme of the utility model: a hot melt adhesive layer is coated on the inner wall of the bag body, and the folding seals at the bottom and side of the bag body are bonded by locally heating the hot melt adhesive layer.
[0007] As a further scheme of the utility model: release paper for protection is arranged on both sides of the sealing glue layer before use.
[0008] As a further scheme of the utility model: the anti-disassembly marks can be some patterns or the text descriptions of being disassembled.
[0009] After the packaging bag of the utility model is sealed, when someone opens the packaging bag, the second sealing glue layer will paste the anti-disassembly marks on the folded opening sealing body together, leaving a mark of being opened, playing a role of leaving a mark when opened, and being safer. Brief Description of the Drawings

[0014] In the figure: 1. Bag body; 101. Hot melt adhesive layer; 2. Folding seal; 3. Fold mouth sealing body; 4. Sealant layer; 401. Sealant layer one; 402. Release layer; 403. Tamper-evident label; 404. Sealant layer two. Specific embodiments
[0015] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, an anti-theft document fold mouth packaging bag includes a bag body 1 and a fold mouth sealing body 3 provided at the top of the bag body 1. The bag body 1 and the fold mouth sealing body 3 are bonded through a sealant layer 4 provided therebetween. The sealant layer 4 includes a sealant layer one 401, a plurality of release layers 402 arranged at equal intervals in the middle area of the sealant layer one 401, tamper-evident labels 403 provided on the upper and lower surfaces of the release layer 402, and a sealant layer two 404 provided on the surface of the tamper-evident label 403.
[0016] By adopting the above technical solution, after the packaging bag is sealed, when someone opens the packaging bag, the sealant layer two 404 will paste the tamper-evident label 403 on the fold mouth sealing body 3 together, leaving a trace of opening, playing a role of leaving a mark when opened, and being safer.
[0017] Among them, a hot melt adhesive layer 101 is coated on the inner wall of the bag body 1, and the folding seals 2 at the bottom and side of the bag body 1 are bonded by locally heating the hot melt adhesive layer 101.
[0018] After adopting the above technical solution, during the production of the packaging bag, it can be quickly pasted by local heating, the gluing process can be omitted, and the efficiency can be greatly improved.
[0019] In this embodiment, release paper for protection is provided on both sides of the sealant layer 4 before use.
[0020] In this embodiment, the tamper-evident label 403 can be some patterns or text descriptions of having been opened.
[0021] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
