[0046] In the following, the first sealing area is defined as the sealing area formed by the sticky note on the bag body, and the second sealing area is defined as the sealing area formed by the extended piece of the bag body to distinguish different embodiments for description.

[0047] Example 1

[0048] like Figure 1-Figure 3 , Fig.13 As shown, this embodiment provides a sticky note integrated packaging bag, including a bag body 1, a bag opening is arranged on the bag body 1, and the bag body 1 is divided into a bag body area 2 and a sealing area 3, and the sealing area 3 is bonded to the bag body area 2 through the adhesive layer 10 on the bag body extension piece 6 to close the bag opening. A sticky note 4 is integrally arranged on the bag body 1, and an adhesive layer and a peeling layer are also arranged on the sticky note 4, and the area of ​​the peeling layer is smaller than the area of ​​the adhesive layer, and a separation dark pattern 5 is arranged on the sticky note 4. The adhesive layer 10 is blocked from stickiness by the release paper 11. The bag body extension piece 6 is formed by extending and folding the front / rear bag body. As shown in the figure, this embodiment arranges the sticky note 4 in the middle of the bag body extension piece on the rear bag body; when sealing, the bag body extension piece 6 is folded, and the bag body extension piece 6 is sealed by the adhesive layer 10 on the bag body extension piece 6. The separation dark pattern 5 can be zigzag, wavy, etc.

[0049] Furthermore, the bag body 1 is provided with a tear line 7. The specific position of the tear line 7 may be on the bag body extension sheet 6 (for example, the adhesive layer 10 is provided on the bag body extension sheet 6, and the tear line 7 is provided at a position staggered from the adhesive layer 10). After the packaging bag is sealed, the inner side surface of the bag body extension sheet 6 is bonded and fixed to the bag surface, and at this time, the bag opening can be directly opened through the tear line 7 to expose the contents of the packaging bag, and then the items in the packaging bag can be taken out.

[0050] The shape, length, width and pattern of the sticky note 4 can be flexibly selected according to the needs. The sticky note 4 is specifically arranged in the middle of the outer side of the bag extension piece 6, and the inner side refers to the side of the bag extension piece 6 where the adhesive layer 10 is arranged, that is, the adhesive side is the inner side; usually the adhesive layer 10 on the bag extension piece 6 is arranged on the side of the folding direction of the bag extension piece 6. Furthermore, the width of the sticky note 4 is smaller than the width of the bag extension piece / bag surface arranged on the bag body 1, preferably the width is ≧2mm, and the length is preferably ≧12.5mm; the connection method can be hot pressing (the self-adhesive label is firmly combined with the bag body 1 by heating) or adhesive bonding.

[0051] In this embodiment, the adhesive layer 10 is specifically a self-adhesive sticker, which is arranged on the bag extension sheet 6, and a release paper is arranged on the surface of the self-adhesive sticker; the sticky note 4 includes a surface paper layer (for displaying patterns), and a self-adhesive sticker is arranged on the back of the surface paper layer. The self-adhesive sticker arranged on the surface paper layer can cover the entire surface paper layer or occupy a part of the surface paper layer. Similarly, the area of ​​the release paper is at least equal to the area of ​​the self-adhesive sticker arranged on the surface paper layer. Common surface materials: coated paper (good printing effect, bright colors), thermal paper (changes color after heating), synthetic paper, special paper, etc.

[0052] Taking the sticky note integrated packaging bag in Example 1 as an example, when packing, tear off the release paper of the sticky note 4 on the bag extension piece 6, and stick the bag extension piece 6 on the bag surface. When opening the packaging bag, you can choose to tear off the sticky note 4. Once the sticky note 4 is torn off, you can know that the packaging bag has been opened; similarly, the bag opening is directly exposed through the tear line 7.

[0053] Example 2

[0054] like Figure 4 As shown, this embodiment provides a note integrated packaging bag, and the difference between this embodiment and embodiment 1 is that the note 4 is integrally arranged at the side end of the bag body extension piece 6, and after the packaging bag is sealed, the note 4 is located at the side end of the bag surface of the packaging bag. The note 4 is arranged at both ends of the bag body extension piece 6, and the note 4 is bonded to the outer side surface of the bag body extension piece 6.

[0055] During packaging, the bag extension sheet 6 is adhered to the bag surface by adhesive tape, and then the sticky note 4 is adhered to another bag surface or the side of the bag body 1 .

[0056] When the note 4 is stuck to the side of the bag body 1, further, a sticker or other sticky colloid is also set on the front side of the paper layer of the note 4. After the note 4 is stuck to the side of the bag body 1, the front side of the note 4 can bond the folded side of the bag body 1 together.

[0057] Example 3

[0058] like Figure 5 As shown, this embodiment provides a packaging bag with an integrated sticky note. The difference between this embodiment and embodiment 2 is that the sticky note 4 is integrally arranged at the side end of the bag body area 2. After the packaging bag is sealed, the sticky note 4 is located at the side end of the bag surface of the packaging bag.

[0059] That is, the setting position of the sticky note 4 is changed from the side end of the bag body extension piece 6 to the side end of the bag body area 2.

[0060] Example 4

[0061] like Figure 6 , Figure 7 As shown, the present embodiment provides an integrated packaging bag for sticky notes, including a bag body 1, a bag opening is arranged on the bag body 1, the bag body 1 is divided into a bag body area 2 and a sealing area 3, the sealing area 3 is bonded to the bag body area 2 through an adhesive layer 10 to close the bag opening, a sticky note 4 is integrally arranged on the bag body 1, an adhesive layer 10 is arranged on the sticky note 4, a separation dark pattern is arranged on the sticky note 4, the adhesive layer 10 is blocked by release paper for isolation of stickiness, and the sealing area 3 is formed by folding the bag body area 2 (that is, the bag body 1 is not provided with a bag body extension piece 6 structure).

[0062] Furthermore, a tear line is provided on the bag body 1 .

[0063] Furthermore, the sticky note 4 is integrally connected to the bag surface of the packaging bag. For the packaging bag of this structure, after the top of the bag body 1 is folded, the sticky note 4 on the bag surface is pasted and limited by the adhesive layer 10.

[0064] Example 5

[0065] On the basis of the packaging bags in Examples 1-3, the adhesive layer 10 arranged on the bag extension piece 6 is directly arranged on the corresponding area on the bag surface, that is, the release paper on the surface of the adhesive layer 10 on the bag surface is torn off, and the bag extension piece 6 can be pasted and fixed after being folded over.

[0066] Example 6

[0067] like Figure 8 As shown, this embodiment provides an integrated packaging bag for sticky notes. The difference between this embodiment and embodiment 2 is that the area of ​​the adhesive layer of the sticky note 4 is equal to the area of ​​the peeling layer, and the sticky note 4 and the bag extension piece 6 share an adhesive layer 10. Sharing an adhesive layer 10 simplifies the packaging bag preparation process and improves the preparation efficiency to a certain extent.

[0068] The width of the sticky note 4 in the present embodiment is at least as wide as the adhesive layer 10. In other embodiments, in a packaging bag structure provided with a bag extension piece 6, the setting position of the sticky note 4 is not necessarily consistent with the setting position of the adhesive layer 10 on the bag extension piece 6 (for example, in Embodiment 1, the adhesive layer 10 of the sticky note 4 set on the top of the bag extension piece 6 is inconsistent with the adhesive layer 10 horizontally set on the back of the bag extension piece 6), making the process of setting the adhesive layer 10 on the bag extension piece 6 and the sticky note 4 more complicated than in the present embodiment.

[0069] In this embodiment, the adhesive layer 10 on the bag extension piece 6 and the sticky note 4 is directly arranged on the bag extension piece 6 and the sticky note 4 to form a common adhesive layer 10 (adhesive layer). When the release paper is arranged, only one strip is arranged to cover the common adhesive layer 10. The bottom layer of the sticky note 4 is on the same layer as the bag body.

[0070] Example 7

[0071] On the basis of the packaging bag in Examples 1-6, the bag body 1 is a paper bag, and a lifting handle 9 is provided on the bag body, or a perforated line is provided on the bag body 1, such as Fig.12 As shown, Fig.12 It also shows the relative relationship between the area of ​​the hot melt adhesive and the release paper 11, that is, the relative relationship between the area of ​​the adhesive layer 10 and the release paper 11 can be flexibly set. In order to facilitate the tearing of the release paper 11, the area of ​​the release paper 11 is usually larger than the area of ​​the adhesive layer 10. Fig.14 As shown, a tearing portion 8 for easy grasping is provided at the side end of the peeling layer (release paper 11).

[0072] Example 8

[0073] like Fig. 9 As shown, this embodiment provides an integrated note packaging bag, wherein the bag body 1 is formed by heat-sealing or sewing a non-woven fabric, the bottom of the bag body 1 is a seamless structure, and a bag body extension piece 6 is provided on the bag body 1.

[0074] The difference between a non-woven packaging bag and a paper bag is mainly reflected in that the connecting line of the bag body 1 of the non-woven packaging bag is located on the side of the bag body 1, and the initial non-woven fabric (rectangular shape) used to fold the non-woven packaging bag is provided, and a crease (V-shaped or W-shaped) is provided in the middle to form the bottom of the bag, so as to achieve a seamless bottom of the finished bag body 1.

[0075] like Figure 7 As shown in the figure, the rearmost side is the bag extension piece 6 structure, on which a self-adhesive sticker is arranged, and on which a release paper is arranged (arranged at a required position to block the stickiness of the self-adhesive sticker), and a tear line 7 can also be arranged on the non-woven bag body 1 to facilitate tearing off the bag extension piece 6, or a lifting handle 9 can be arranged by hot pressing connection.

[0076] Example 9

[0077] On the basis of the packaging bag in Examples 1-8, the adhesive layer 10 is replaced with a re-stickable adhesive layer, such as: self-adhesive stickers, double-sided adhesive tape (specifically, ordinary double-sided adhesive tape, foam double-sided adhesive tape, etc., which can be re-sticked), etc., to achieve re-sticking and use of the bag opening. A re-stickable adhesive layer is provided on the sticky note 4, and when the user opens it, he can judge whether it has been opened by the sticky note 4, and the adhesive part of the bag body 1 will not be damaged, so it can be re-used.

[0078] Example 10

[0079] Reference Fig.10 As shown, compared with Example 1, in this embodiment, the sticky note 4 is arranged on the inner side (adhesive side) of the bag extension piece 6, and the sealing is achieved by arranging an adhesive layer 10 on the bottom surface of the sticky note 4 beyond the top end of the bag extension piece 6. In this embodiment, since the sticky note 4 is arranged on the inner side of the bag extension piece 6, the adhesive layer 10 on the bag extension piece 6 and the adhesive layer 10 on the sticky note 4 overlap.

[0080] Furthermore, a tear line 7 is provided on the bag body 1 .

[0081] Embodiment 11

[0082] Reference Fig.11 As shown, compared with Example 2, this embodiment sets the note 4 on the inner side (adhesive side) of the bag extension piece 6, and the adhesive layer 10 on the note 4 is staggered from the adhesive layer 10 on the bag extension piece 6, and is located below the original adhesive layer 10 of the bag extension piece 6. Based on this structure, the width of the bag extension piece 6 will increase.

[0083] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
