When in use, after the express items are loaded, tear off the isolation paper on the double-sided tape provided on the inner side of the upper movable sealing end, fold back the upper movable sealing end and seal it tightly, and the packaging is completed at this time, but this type of express packaging bag cannot be used multiple times.

[0004] The present invention is proposed in view of the deficiencies in the prior art. [Summary of the invention]

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an express packaging bag.

[0006] The present invention can be implemented by the following technical solutions:

[0007] The present invention discloses an express packaging bag, comprising a rear film and a front film, wherein both sides and the bottom of the rear film are fixed to the front film, a sealing film is further provided on one side of the rear film, both sides of the sealing film are fixed to both sides of the rear film, the sealing film and the rear film are further connected via a connecting film, a tearing opening formed by puncturing is provided on the connecting film, an adhesive tape is fixed on the side of the sealing film close to the front film, an adhesive tape is also fixed on the side of the front film close to the rear film, and the adhesive tape consists of a self-adhesive sticker and a release film covering the self-adhesive sticker. When the packaging bag is used, the items to be delivered are put into the bag body formed by the front side film and the rear side film through the sealing film and the front side film, and the release film of the self-adhesive on the surface of the sealing film is torn off, and the sealing film is sealed with the front side film and the sealing film through the self-adhesive to realize the delivery after sealing. After being quickly delivered to the designated position, the connecting film is torn off from the tearing position, and the express is taken out from between the sealing film and the rear side film. When the packaging bag is used again, the express is put into the bag body formed by the rear side film and the front side film again from between the sealing film and the rear side film, and the release film on the self-adhesive on the front side film is torn off, and the front side film and the rear side film are sealed with the self-adhesive to deliver the express again. After the packaging bag with this structure is used, the express can be sealed and delivered again, which greatly reduces the amount of packaging bags used in express delivery.

[0008] Preferably, the cross-section of the connecting membrane is a V-shaped structure.

[0009] Preferably, the front film is also provided with ventilation holes penetrating the front film, so that the air in the packaging bag can be discharged through the ventilation holes to prevent the packaging bag from being squeezed and burst.

[0010] Preferably, corresponding positions on the rear side film and the sealing film are provided with carrying openings, through which the express delivery can be more conveniently carried.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] The packaging bag of this structure can be used to seal and transport the express again after use, which greatly reduces the amount of packaging bags used in express delivery.
