Description

Technical Field

[0001] The utility model relates to the technical field of packaging containers, in particular to a wet wipe packaging bag. Background Art

[0002] A wet wipe packaging bag is an outer packaging material for packaging wet wipe products, which has the functions of protecting wet wipes, facilitating carrying and using. During the use of the existing wet wipe packaging bag, the adhesive surface of the unsealing label set at the opening is likely to lose its adhesiveness due to dust or water contamination, resulting in the failure of sealing, the loss of moisture of the wet wipes, and some wet wipe packaging bags are provided with a locking cover at the opening, and the sealing cover has problems of inconvenient opening and poor sealing performance, which will also cause the loss of moisture of the wet wipes and affect the use.

[0003] In view of the above problems, the patent document with the authorization announcement number CN212830399U discloses a wet wipe packaging bag. The packaging bag is provided with a magnetic absorption sealing cover at the top opening of the bag body. The magnetic absorption sealing cover includes a rectangular bottom frame and a cover plate hinged to the rear end of the rectangular bottom frame. A sheet magnet is fixed at the lower end inside the rectangular bottom frame. The lower surface of the sheet magnet is fixed to the top of the bag body by glue. A through hole for the opening to expose is also opened in the middle of the sheet magnet. A silica gel sheet is fixed to the upper surface of the sheet magnet by glue. A block magnet that mutually attracts with the sheet magnet is fixed to the inner side of the cover plate. The opening is sealed by the mutual attraction of the block magnet and the sheet magnet, and the gap between the attracting surfaces of the block magnet and the sheet magnet is filled by the silica gel sheet to improve the sealing performance of the magnetic absorption sealing cover and further prevent the loss of moisture of the wet wipes.

[0004] However, although the above wet wipe packaging bag enhances its sealing performance by setting a magnetic absorption sealing cover at the opening, the two ends of the existing wet wipe packaging bag are usually heat-sealed. During heat-sealing, the inner sealing part of the packaging film is the heat-sealing layer of the packaging film, and the outer sealing part of the packaging film is the printing layer of the packaging film. The printing layer of the packaging film has good heat resistance, resulting in insufficient firm adhesion during heat-sealing and plastic sealing, so that it is easy to open during use, affecting the sealing performance of the wet wipe packaging bag, and the moisture of the wet wipes is easy to lose from the opened part, affecting the preservation and use of the wet wipes. Summary of the Utility Model

[0005] The utility model provides a wet wipe packaging bag to solve the technical problem that the adhesion of the two ends of the sealing part of the existing wet wipe packaging bag is poor, resulting in easy opening during use, and thus the moisture of the wet wipes is lost from the opened part.

[0006] To solve the above problems, the wet wipe packaging bag provided by the utility model adopts the following technical solutions:

[0007] A wet wipe packaging bag, comprising:

[0008] The main body of the packaging bag has a drawing opening on its top surface for taking out wet wipes, with seals at both ends, and the drawing opening is equipped with a sealing cover plate;

[0009] It further includes:

[0010] Both ends of the seal have folding corner segments, and each folding corner segment includes an upper folding corner and a lower folding corner arranged corresponding to each other up and down. The top surface and the side surface of the main body of the packaging bag are heat-sealed to form the upper folding corner, and its bottom surface and the side surface are heat-sealed to form the lower folding corner;

[0011] An adhesive, which is located between the upper folding corner and the lower folding corner for bonding the upper folding corner and the lower folding corner.

[0012] The beneficial effects of the wet wipe packaging bag provided by the present utility model are as follows: By providing folding corner segments including upper and lower corresponding upper and lower folding corners at both ends of the seal, and arranging an adhesive between the upper folding corner and the lower folding corner to bond the upper folding corner and the lower folding corner, the reliability of the connection at both ends of the seal is enhanced, effectively avoiding the situation of unsealing at both ends of the seal during use, enhancing the sealing performance of the wet wipe packaging bag, and reducing the possibility of moisture in the wet wipes being lost during storage. Through the above settings, the present utility model has completed the improvement and upgrade of the existing wet wipe packaging bag, effectively solving the technical problem that the adhesion at both ends of the seal of the existing wet wipe packaging bag is poor, resulting in easy unsealing during use, and thus causing the loss of moisture in the wet wipes from the unsealed part.

[0013] Further, the adhesive is provided at the corner of the main body of the packaging bag.

[0014] Further, the adhesive is a hot melt adhesive.

[0015] Beneficial effects: The hot melt adhesive is a new type of environmentally friendly material without solvents and with low price. It has excellent adhesion strength and flexibility, can firmly bond the upper folding corner and the lower folding corner, and has no risk of flammability or explosion during processing and transportation. At the same time, it does not produce volatile organic compound pollution, and the waste can be naturally degraded without harming the environment.

[0016] Further, the main body of the packaging bag sequentially includes a film printing layer, a film heat-sealing layer, a film heat-sealing layer, and a film printing layer from top to bottom, and a receiving cavity for accommodating wet wipes is formed between the two film heat-sealing layers.

[0017] Further, the seals are located at both ends in the length direction of the main body of the packaging bag.

[0018] Further, the seal has multiple parallel heat-sealing lines.

[0019] Further, the extending direction of the heat-sealing lines is parallel to the width direction of the main body of the packaging bag.

[0020] Furthermore, the extraction port is located at the central position of the packaging bag body. BRIEF DESCRIPTION OF THE DRAWINGS

The packaging bag body 9 successively includes a film printing layer 6, a film heat-sealing layer 7, a film heat-sealing layer 7, and a film printing layer 6 from top to bottom. An accommodation cavity 8 for accommodating wet wipes is formed between the two film heat-sealing layers 7. An extraction opening is provided on the top surface of the packaging bag body 9, and both ends in its length direction have seals 1.

[0033] Specifically, the extraction opening is located at the central position of the packaging bag body 9, and the extraction opening is equipped with a sealing cover plate 2.

[0034] Specifically, both ends of the seal 1 have folding corner segments. The folding corner segments include upper folding corners 3 and lower folding corners 4 that correspond up and down. An adhesive 5 is provided between the upper folding corner 3 and the lower folding corner 4.

The upper folding corner 3 and the lower folding corner 4 are firmly bonded together by a hot melt adhesive, which can effectively enhance the reliability of the connection between the upper folding corner 3 and the lower folding corner 4, thereby enhancing the sealing performance of the seal 1 and effectively preventing the moisture in the wet wipes from losing during storage.

[0038] Embodiment 2 of the wet wipe packaging bag provided by the present utility model:

[0039] The main difference from Embodiment 1 lies in that:

[0040] In Embodiment 1, the extending direction of the heat-sealing line is parallel to the width direction of the packaging bag body.

[0041] In this embodiment, the extending direction of the heat-sealing line is perpendicular to the width direction of the packaging bag body.

[0042] Embodiment 3 of the wet wipe packaging bag provided by the present utility model:

[0043] The main difference from Embodiment 1 lies in that:

[0044] In Embodiment 1, the adhesive is a hot melt adhesive.

[0045] In this embodiment, the adhesive is an acrylate adhesive or a pressure-sensitive adhesive.
