The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0026] Example

[0027] like Figure 1 , 4 As shown, this embodiment provides a new type of packaging bag, including a bag body 1, which is enclosed to form a containing cavity; two folding parts, which are respectively arranged at the two ends of the bag body 1 in the enclosing direction, and one folding part is tightly stacked on the outer surface of the bag body 1 after being attached to the other folding part; two sealing parts 2, which are respectively arranged at the two ends of the bag body 1 in its own length direction to seal the containing cavity; wherein the bag body 1, the two folding parts and the two sealing parts 2 are an integrated structure.

[0028] Specifically, the accommodating cavity formed by the bag body 1 acts as a container for containing coffee powder, milk powder, powdered or granular medicines, etc. The two folding parts are used to seal the opening of the bag body 1 in the enclosing direction, and the two sealing parts 2 are used to seal the two openings of the bag body 1 in its own length direction. The folding parts and the sealing parts 2 are both used to assist in the formation of the accommodating cavity. The two folding parts are tightly stacked into an integrated structure to seal the opening of the bag body 1 in the enclosing direction. Since the bag body 1 and the two folding parts are an integrated structure, after the two folding parts are tightly stacked, in addition to sealing the two openings of the bag body 1 in its own length direction, they can also support the bag body 1, enhance the stiffness of the bag body 1, and make the bag body 1 not easy to bend. After brewing, since the bag body is not easy to bend, the brewed solution can also be stirred through the bag body 1, thereby enhancing the functionality of the bag body 1.

[0029] In detail, the packaging bag is formed by a packaging coil. A packaging coil can be divided into two folded parts on both sides and a forming part for forming a bag body 1 located between the two folded parts along its width direction. A packaging coil can be divided into sealing parts 2 located at both ends along its length direction. During the forming process of the packaging bag, the forming part is rolled to form the bag body 1, and the two folded parts on both sides are tightly stacked into an integrated structure. Preferably, the two folded parts are formed into an integrated structure by hot pressing. Of course, the integrated structure can also be formed by other methods, such as gluing, etc., which are not limited here. A suitable connection method can be selected according to the material of the packaging coil. After rolling, the sealing parts 2 at both ends form an annular structure and form a cavity therein. The sealing part 2 is flattened and sealed to close the cavity formed after the sealing part 2 is rolled. Preferably, the cavity is formed after flattening and sealing. Figure 3 In the structure shown, more preferably, the sealing portion 2 is flattened and sealed by heat pressing. Of course, it can also be sealed in other ways, such as gluing, etc., which is not limited here. Just choose a suitable sealing method according to the material of the packaging coil.

[0030] Preferably, the cross section of the middle portion of the bag body 1 is circular or elliptical, and the bag body 1 is pillow-shaped as a whole.

[0031] like Figure 1 , 4 -6, further, the two folding parts include a first folding part 5 and a second folding part 6, and the first folding part 5 is arranged farther away from the bag body 1 than the second folding part 6; the packaging bag also includes: an extension part 3, which is connected to the first folding part 5, and at least a part of the extension part 3 is overlapped between the second folding part 6 and the bag body 1, the first folding part 5 is longer than the second folding part 6, and the part of the first folding part 5 that exceeds the second folding part 6 is regarded as the extension part 3, at least a part of which is overlapped between the second folding part 6 and the bag body 1, and is respectively connected to the second folding part 6 and the bag body 1. Through the arrangement of the extension part 3, the connectivity between the first folding part 5 and the second folding part 6 and the bag body 1 is made stronger, and the first folding part 5, the second folding part 6, the extension part 3 and the bag body 1 form a 4-layer structure, and the 4-layer structure is sealed to each other and has a certain rigidity, which can support and strengthen the bag body 1. Preferably, the extension portion 3 is connected to the second folding portion 6 and the bag body 1 by hot pressing. Of course, the integrated structure can also be formed by other methods, such as gluing, etc., which is not limited here. Just choose a suitable connection method according to the material of the packaging coil.

[0032] like Figure 1 , 2As shown, further, the packaging bag also includes: at least one opening 4, extending from the extension portion 3 to the first folding portion 5 and the second folding portion 6, and the portion of the extension portion 3 located on the side of the opening 4 away from the sealing portion 2 is overlapped between the second folding portion 6 and the bag body 1. The portion of the extension portion 3 located on the side of the opening 4 close to the sealing portion 2 is called a bag ear (or a tab), and the user can pinch the bag ear without using a cutting tool and tear one end of the bag body 1 off the bag body 1 along the direction of the opening 4, so that the relevant personnel can open the bag body 1.

[0033] Furthermore, there are two openings 4, which are arranged at intervals on the extension part 3, and a portion of the extension part 3 between the two openings 4 is overlapped between the second folded part 6 and the bag body 1. Openings 4 and bag ears are arranged at both ends of the bag body 1, which is convenient for users to open the bag body 1, and the two openings 4 and bag ears are also helpful to improve the stability of the packaging bag. When one opening 4 cannot open the bag body 1, the other opening 4 can be used.

[0034] Further, the extension depth of the opening 4 on the first folded portion 5 and the second folded portion 6 is 1 / 4 to 3 / 4 of the width of the second folded portion 6. Preferably, the extension depth of the opening 4 on the first folded portion 5 and the second folded portion 6 is 1 / 2 of the width of the second folded portion 6.

[0035] Furthermore, the two folding portions are arranged offset from the center line of the bag body 1. Preferably, the two folding portions are arranged on the side edges of the bag body 1. By arranging the two folding portions on the side edges of the bag body 1, the rigidity of the bag body 1 is enhanced, making the bag body 1 less likely to bend.

[0036] Furthermore, the bag body 1 includes a straw layer and an outer film layer arranged on a side of the straw layer away from the accommodating cavity. During specific use, the user can tear off the outer film layer on the bag body 1, and tear off or cut off both ends of the bag body 1, thereby forming a straw for drinking beverages or instant medicines. Preferably, the peel strength of the straw layer and the outer film layer is 0.1N / 15mm~10N / 15mm, and more preferably, the peel strength of the straw layer and the outer film layer is 0.5N / 15mm~2N / 15mm, so that the user can peel off the outer film layer from the straw layer.

[0037] Furthermore, an ink layer is provided on the side of the outer film layer away from the straw layer. The ink layer gives the outer film layer an aesthetic appearance, and due to the barrier of the outer film layer, the risk of ink migration to the straw layer or the accommodating cavity is reduced; after the outer film layer connected to the ink layer is peeled off, the straw layer can be prevented from being contaminated by ink, the separation and classification of packaging waste is achieved, the difficulty of recycling the straw layer is reduced, and the overall recycling value of the waste packaging bag is improved.

[0038] Furthermore, the straw layer includes at least two PE material layers and an AL material layer arranged between the two PE material layers; the outer film layer includes at least one PET material layer.

[0039] Furthermore, an adhesive is provided between the straw layer and the outer film layer. The adhesive is preferably a polyurethane adhesive. After the adhesive is applied, the straw layer and the outer film layer are compositely connected by heating or extrusion.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
