When used a second time, tear the seal between one side of the envelope leaf and the envelope bag by tearing the seal strip to open the envelope bag, and then turn the other side of the envelope leaf outwards to seal it to the other side of the envelope bag for reuse.

[0007] As a further embodiment of this invention, a sealing layer is provided on the surface of the envelope leaf, and adhesive areas are provided on both sides of the envelope. The sealing layer uses PVA adhesive strip material to seal the envelope.

[0008] As a further embodiment of this invention, the lower end of the tear strip is provided with a folding area, which facilitates guidance for users on how to use the envelope more properly.

[0009] As a further embodiment of this utility model, a marking area is provided on the right side of the folded area. The marking area is mainly used to indicate the order of use of the envelope bag for the first and second times.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. When using this utility model, the symmetrical envelope leaf structure is used to fold the envelope leaf in half and press the adhesive strip to the adhesive area of ​​the envelope to seal the pocket. After the envelope is sealed, it can be used for mailing. When used for a second time, the envelope pocket can be torn open by tearing the strip to retrieve the package. The same steps as the first time are required. The second sealing is achieved after the first sealing, which solves the problem of existing envelopes being unable to be reused multiple times, resulting in paper waste and failing to achieve the goal of environmental protection.

[0011] 2. When this utility model is used, the sealing structure of the envelope is simulated as the shape of a leaf, and structures such as folding area and marking area are set. When in use, it not only has an aesthetic effect, but also guides the user to operate and use the envelope in a convenient way, thus achieving the effect of fitting the theme of environmental protection and making the envelope easy for users to use.

[0015] To address the problem of this situation, this utility model provides a reusable envelope.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] It should be noted that, for the sake of understanding this embodiment, the envelope in the accompanying drawings of this embodiment has been thickened. This is only to make it easier to understand the structural features of the envelope. If the thickness of the envelope in the accompanying drawings causes the envelope leaf to be unable to be folded, this problem can be ignored.

[0018] Please see Figure 1This utility model provides a reusable envelope bag, including an envelope bag 1 and an envelope leaf 2. The number of envelope leaves 2 is two and they are symmetrically arranged above the envelope bag 1. A tear strip 22 is provided between the envelope bag 1 and the envelope leaf 2. When not in use, both envelope leaves 2 are folded inwards on the inside sides of the envelope 1; When using it for the first time, the envelope leaf 2 on the inside out can be sealed to the outside of the envelope 1. When used for the second time, tear the seal 2 on one side of the envelope leaf 2 and the envelope 1 with the tear strip 22 to open the envelope 1, and fold the other side of the envelope leaf 2 outward to seal it with the other side of the envelope 1 for reuse.

[0019] Please see Figure 2 In some embodiments, the surface of the envelope leaf 2 is further provided with a sealing layer 21, and adhesive areas 24 are provided on both sides of the letter bag 1.

[0020] The sealing layer 21 uses PVA adhesive strip material to seal the envelope 1. The sealing layer 21 is designed with a blade structure, which conforms to the theme of energy conservation and environmental protection of this application. At the same time, it is more aesthetically pleasing when in use. When using it, you only need to tear off the adhesive strip of the sealing layer 21 and stick it to the corresponding adhesive area 24 set on the envelope 1 to complete the sealing of the envelope.
