These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0040] The specific implementation process of the present invention will be elaborated below through multiple embodiments.

[0041] Embodiment 1

[0042] Refer to Figures 1 to 6 , this embodiment discloses a specific implementation manner of a bag mouth anti - tampering protection seal strip (hereinafter referred to as "protection seal strip").

[0043] Refer to Figures 1 to 6 , the bag mouth anti - tampering protection seal strip includes a substrate 1; an adhesive area 11 and a blank area 12 are provided on the first surface (A surface) of the substrate 1; an identification layer 2, an adhesive layer 3 and a first release layer 4 are provided on the second surface (B surface) of the substrate 1; the identification layer 2 includes a first printing layer 21, a first gold oil identification layer 22, a second printing layer 23 and a second gold oil identification layer 24, the first printing layer 21 is an intaglio layer, and the second printing layer 23 is a relief layer; the identifications shown by the first printing layer 21, the first gold oil identification layer 22, the second printing layer 23 and the second gold oil identification layer 24 are overprinted.

[0044] Specifically, Figure 1 is a plan view of an express delivery, take - out, or document delivery bag, including a bag body 5 and a bag tongue 6. The adhesive area 11 on the first surface (A surface) of the protection seal strip is adhered to the bag tongue 6, and the blank area 12 extends out of the bag tongue 6. After tearing off the first release layer 4, the bag tongue 6 is folded 180° towards the bag body 5, so that the second surface (B surface) of the substrate 1 is adhered to the bag body, realizing the closure of the express delivery, take - out, or document delivery bag. For the effect diagram after closure, refer to Figure 2 .

[0045] The anti - tampering principle is as follows: Refer to Figure 3, on the second side (side B) of the base material 1, an identification layer 2, an adhesive layer 3, and a first release layer 4 are provided; the identification layer 2 is successively printed to form a first printing layer 21, a first varnish identification layer 22, a second printing layer 23, and a second varnish identification layer 24. The identifications shown by the first printing layer 21, the first varnish identification layer 22, the second printing layer 23, and the second varnish identification layer 24 are overprinted. An example of the overprinted content is shown in Figure 6 , wherein, the first printing layer 21 is an intaglio layer, that is, the area where the identification is shown is blank and other areas are fully inked; the first varnish identification layer 22 is an identification formed by varnish printing and is overprinted on the blank area of the first printing layer 21; the second printing layer 23 is a relief layer, that is, the area where the identification is shown is ink and other areas are blank. The ink at the identification area of the second printing layer 23 is overprinted on the first varnish identification layer 22; the second varnish identification layer 24 is an identification formed by varnish printing and is overprinted on the ink at the identification area of the second printing layer 23; the adhesive layer 3 is coated on the surface of the second varnish identification layer 24. Since only the identification areas of the first varnish identification layer 22, the second printing layer 23, and the second varnish identification layer 24 have ink, the adhesive layer 3 also adheres to the non-blank area of the first printing layer 21; when the seal strip is in the Figure 2 state shown, if someone tears open the blank area 12 in advance during the process of delivering express delivery, takeout, or documents, since the adhesive force between the adhesive layer 3 and the bag body 5 is greater than the adhesive force between the adhesive layer 3 and the second varnish identification layer 24, during the process of tearing open the blank area 12, since the second printing layer 23 is sandwiched between the first varnish identification layer 22 and the second varnish identification layer 24, a part of the second printing layer 23 is adhered by the base material 1, and another part of the second printing layer 23 still adheres to the surface of the bag body 5. Also, since the part of the second printing layer 23 adhered by the base material 1 is irregular, even if it is pasted back in place, it is impossible to restore it again, and there will still be traces of the second printing layer 23 being separated; the tearing trace can be observed through the blank area, making the unsealing trace visible, so as to prevent express delivery, takeout, and document transfer bags from being opened.

[0046] To facilitate tearing the seal strip, a starting area 13 is further provided at the edge of the first side (side A) of the base material 1. An starting area printing layer, an adhesive layer 3, and a barrier layer 7 are provided on the second side (side B) of the base material 1 corresponding to the starting area 13. To save processes, the pattern of the starting area printing layer and the identification of the first printing layer 21 are printed in the same process. The pattern of the starting area printing layer is also intaglio. For details, see Figure 4; The adhesive area 11 and the blank area 12 are both arranged along the length direction of the preservation seal strip. The base material is a transparent or semi-transparent material. The blank area 12 and the starting area 13 are exposed outside. A starting area printing layer is provided on the second surface of the base material corresponding to the starting area 13, and words such as "OPEN HERE" are printed on the starting area printing layer, enabling users to clearly see the starting point for opening the preservation seal strip and facilitating use; the purpose of the barrier layer 7 is to prevent the adhesive layer 3 in the starting area 13 from sticking to the bag body 5, playing a barrier role and facilitating the tearing of the preservation seal strip through the starting area 13.

[0047] In a preferred embodiment, both the adhesive area 11 and the adhesive layer 3 use PSA glue. When bonding the bag body 5, a certain pressure is applied for pressing to make the bonding force of the PSA glue stronger; both the first release layer 4 and the barrier layer 7 use PET film or OPP film.

[0048] Embodiment 2

[0049] See Figure 7 , the preparation process of the bag mouth anti-tampering preservation seal strip includes the following steps:

[0050] Step S1: See Figures 1 to 6 , on the first surface (A surface) of the transparent or semi-transparent base material 1, an adhesive is coated on the adhesive area 11 while retaining the blank area 12 and the starting area 13. A release layer 14 is compounded on the adhesive area 11. When using the preservation seal strip, first tear off the release layer 14, bond the adhesive area 11 to the bag tongue 6, and make the blank area 12 and the starting area 13 extend out of the bag tongue 6;

[0051] Step S2: The first printing layer 21, the first gold oil identification layer 22, the second printing layer 23, and the second gold oil identification layer 24 are successively printed on the second surface of the base material 1. The first printing layer 21 is divided into an identification area printing layer 211 and a starting area printing layer 212. The first gold oil identification layer 22, the second printing layer 23, and the second gold oil identification layer 24 are only printed on the identification area printing layer 211; specifically, the identifications shown by the first printing layer 21, the first gold oil identification layer 22, the second printing layer 23, and the second gold oil identification layer 24 are overprinted. Among them, the first printing layer 21 is an intaglio layer, that is, the area where the identification is shown is blank while the other areas are fully inked; the first gold oil identification layer 22 is an identification formed by gold oil printing and overprinted on the blank area of the first printing layer 21; the second printing layer 23 is a relief layer, that is, the area where the identification is shown is ink while the other areas are blank, and the ink at the identification area of the second printing layer 23 is overprinted on the first gold oil identification layer 22; the second gold oil identification layer 24 is an identification formed by gold oil printing and overprinted on the ink at the identification area of the second printing layer 23.

[0052] Step S3: Coat an adhesive layer 3 on the area corresponding to the identification area printing layer 211 and the area corresponding to the start area printing layer 212; specifically, the adhesive layer 3 is coated on the area corresponding to the identification area printing layer and the area corresponding to the start area printing layer.

[0053] Step S4: Laminate a barrier layer 7 on the surface of the adhesive layer 3 in the area corresponding to the start area printing layer 212; the purpose of the barrier layer 7 is to ensure that the start area 13 will not stick to the bag body 5.

[0054] Step S5: Laminate a first release layer 4 on the surface of the adhesive layer 3 in the area corresponding to the identification area printing layer 211 and the barrier layer 7. Specifically, since only the marked areas of the first varnish identification layer 22, the second printing layer 23, and the second varnish identification layer 24 have ink, the adhesive layer 3 also adheres to the non-blank area of the first printing layer 21; when the Figure 2 sealing strip is in the state as shown, if someone tears open the blank area 12 in advance during the process of delivering express, takeout, or documents, since the adhesive force between the adhesive layer 3 and the bag body 5 is greater than the adhesive force between the adhesive layer 3 and the second varnish identification layer 24, during the process of tearing open the blank area 12, since the second printing layer 23 is sandwiched between the first varnish identification layer 22 and the second varnish identification layer 24, a part of the second printing layer 23 is lifted by the substrate 1, and another part of the second printing layer 23 still adheres to the surface of the bag body 5. Also, since the part of the second printing layer 23 lifted by the substrate 1 is irregular, even if it is stuck back in place, it is impossible to restore it to its original state, and there will still be traces of the separation of the second printing layer 23; the tearing traces can be observed through the blank area, making the unsealing traces visible, so as to prevent express, takeout, and document transfer bags from being opened.

[0055] In a preferred embodiment, both the adhesive area 11 and the adhesive layer 3 use PSA glue. When bonding the bag body 5, press it with a certain pressure to make the bonding force of the PSA glue stronger; both the first release layer 4 and the barrier layer 7 use PET film or OPP film.

[0056] Embodiment 3

[0057] The takeout sealing bag, see Figure 1 and Figure 2 includes a bag body 5 and a bag tongue 6, and the bag mouth anti-unsealing and protecting sealing strip described in Embodiment 1 is adhered between the bag tongue 5 and the bag body 6.

[0058] Specifically, Figure 1It is a plan view of an express delivery, takeout, and document transfer bag, including a bag body 5 and a bag tongue 6. First, tear off the release layer 14 to expose the adhesive area 11. The adhesive area 11 on the first side (A side) of the seal strip is adhered to the bag tongue 6, and the blank area 12 extends out of the bag tongue 6. After tearing off the first release layer 4, the adhesive layer 3 and the barrier layer 7 are exposed. The bag tongue 6 is folded 180° towards the bag body 5, so that the second side (B side) of the substrate 1 is adhered to the bag body, realizing the closure of the express delivery, takeout, and document transfer bag. For the effect diagram after closure, see Figure 2 。

[0059] The technical solutions of the takeout seal bag disclosed in this embodiment that are the same as those in Embodiment 1 are described in Embodiment 1 and will not be repeated here.
