[0010] Further, the inner wall and the outer surface of the envelope bag body are fixedly connected with an adhesive layer.

[0011] Through the above scheme, the adhesive layer can close the envelope bag body, avoiding the moisture from the outside entering the envelope bag body to damage the internal items.

[0012] Further, the label layer is smooth and non-stick.

[0013] Through the above scheme, the label layer is smooth and non-stick, which can facilitate tearing off the express delivery slip and facilitate the reuse of the envelope bag, saving energy and protecting the environment.

[0014] Further, the waterproof layer is made of polyethylene material.

[0015] Through the above scheme, the waterproof layer made of polyethylene material can improve the waterproof performance of the envelope bag body, avoiding the moisture from the outside entering the envelope bag body to affect the internal items.

[0016] Further, the contact layer is internally mounted with two mesh baskets, and the two mesh baskets are internally placed with drying agents.

[0017] Through the above scheme, the drying agent can keep the items in the envelope bag body dry, avoiding dampness and mildew.

[0018] Further, the contact layer is made of non-woven fabric material.

[0019] Through the above scheme, the contact layer made of non-woven fabric material can facilitate human contact and facilitate the use of people with sensitive skin.

[0020] Further, the buffer layer is made of sponge material.

[0021] Through the above scheme, the buffer layer made of sponge material can make the whole more portable, and its flexibility is stronger, and the buffering capacity is higher.

[0022] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:
