[0001] This utility model relates to the field of fast-moving consumer goods packaging technology, and in particular to a sealing label sticker. Background Technology

[0002] Fast-moving consumer goods (FMCG) packaging bags typically lack a closure or have a one-time seal. During use, an external sealing label is often needed to keep the bag closed, and this label also serves an identification function, indicating the contents or displaying the brand logo. Currently, many traditional labels use ordinary permanent adhesive. After peeling off the label, it is easily damaged, and the adhesive tends to detach and leave residue at the bag opening, hindering reuse. Therefore, users often need to apply new labels when frequently opening and closing the bag, impacting the user experience. Thus, developing a reusable sealing label suitable for applications involving multiple openings and closings is a pressing issue that needs to be addressed. Utility Model Content

[0023] Figure 2 This is a vertical cross-sectional structural diagram of an embodiment of the present utility model;

[0024] Figure 3 This is a rendering of the appearance of an embodiment of the present utility model. Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 and Figure 2 As shown, the sealing label 1 in this embodiment includes a label body layer 2, an outer adhesive layer 3, and an outer protective layer 4; the label body layer 2, the outer adhesive layer 3, and the outer protective layer 4 are stacked sequentially from bottom to top; a fixing layer 2a is provided on the back of the sealing label 1, i.e., the bottom surface of the label body layer 2, which is used to firmly bond the sealing label 1 to the surface of the packaging bag to prevent the label from falling off; the label body layer 2 includes a printable layer 2b and an intermediate layer 2d, with the intermediate layer 2d stacked on top of the printable layer 2b, and the intermediate layer 2d and the printable layer 2b are fixedly connected by an inner adhesive layer 2c; the printable layer 2b can be used to set label patterns, such as displaying the contents identification, trademark LOGO, and other pattern information on a white background, or it can be left unprinted and only display the white background, and the gloss effect of the pearlescent PP paper can improve the appearance of the label; the intermediate layer 2d is a transparent layer and does not affect the display of the printable layer 2b. In a preferred embodiment, the printable layer 2b comprises pearlescent PP paper; the intermediate layer 2d comprises PET film. The pearlescent PP paper has relatively low strength, and the intermediate layer 2d provides protection, improving the durability of the sealing label 1. The outer adhesive layer 3 is fixedly disposed on the label body layer 2 for temporary fixation between the sealing label 1 and the bag opening. The outer adhesive layer 3 and the bag opening can be repeatedly torn open and re-fixed, allowing the sealing label 1 to be reused multiple times. The outer adhesive layer 3, intermediate layer 2d, and inner adhesive layer 2c form a double-sided adhesive structure, protecting the printable layer 2b from scratches during use. In a preferred embodiment, the fixing layer 2a and inner adhesive layer 2c are permanent adhesives, while the outer adhesive layer 3 is a removable or partial application of permanent adhesive; it is sufficient to ensure that when peeled off, the outer adhesive layer 3 separates from the externally bonded bag opening while the label body layer 2 remains firmly connected to the packaging bag. Before using the sealing label 1, the upper surface of the outer adhesive layer 3 is covered with an outer protective layer 4. The outer protective layer 4 is a paper layer or a thin plastic layer coated with release oil (hydroxypropyl silicone oil or other release agents). It can be a transparent or opaque material, such as pearlescent PP paper or PET film. In a preferred embodiment, the outer protective layer 4 is provided with a peel-off prompt pattern to remind the user to peel it off before use when the outer protective layer 4 is covering the outer adhesive layer 3. The label body layer 2 and the outer protective layer 4 have the same shape and size, both being circles with a protrusion to facilitate peeling off the outer protective layer 4.

[0027] Before use, such as Figure 3 As shown, multiple sealing labels 1 can be arrayed on a carrier backing paper 5 for individual use. The carrier backing paper 5 includes glassine paper, and the back of the label body layer 2 is adhered to the carrier backing paper 5. When the sealing label 1 is removed, the fixing layer 2a remains on the back of the label body layer 2. In use, the sealing label 1 is removed from the carrier backing paper 5 and fixedly affixed to the packaging bag near the bag opening, with a gap between the bag opening and the bag opening. When the bag opening is opened and contents are filled, and the bag opening needs to be temporarily closed, the outer protective layer 4 can be peeled off, and the bag opening can be folded or rolled up to the sealing label 1, so that the bag opening and the outer adhesive layer 3 of the sealing label 1 are adhered and fixed, preventing air circulation between the inside and outside of the packaging bag. When the bag opening needs to be opened or closed again, since the outer adhesive layer 3 does not leave residue or sticky marks on the bag opening but remains on the surface of the sealing label 1 and maintains its adhesiveness, the bag opening can be easily peeled off or re-adheded and fixed. The multi-layer structure of this embodiment makes the label pattern more resistant to external scratches and other damage factors, maintaining the pattern's clarity and aesthetics. It can also be repeatedly used for sealing, and the peeling and sticking methods are simple, reducing operational hassles and improving the user experience.
