[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0024] Referring to the drawings, in the embodiments of the present application, a shock-absorbing paper bag includes an outer bag 1 and an inner bag 2. The inner bag 2 includes an inner paper composite material 3. The inner paper composite material 3 includes a shock-absorbing paper layer 4 and a support paper layer 5. The support paper layer 5 is located on the inner side of the shock-absorbing paper layer 4. The shock-absorbing layer and the support paper layer 5 are connected to form the inner paper composite material 3. The support paper layer 5 can support the shock-absorbing layer, and the shock-absorbing layer is attached to the support paper layer 5. The inner paper composite material 3 is folded to form the inner bag 2 in the shape of a flattened paper tube with an upper opening and a lower opening. The inner paper composite material 3 can be folded in a circle by circle manner.

[0025] The structure of the inner bag 2 not only has a shock-absorbing function, but also is in the shape of a flattened paper tube with an upper opening and a lower opening. The connection strength and support force of the left and right sides are relatively good. The inner bag 2 is lined in the outer bag 1 to form a shock-absorbing paper bag. The outer bag 1 includes an outer paper layer 6. The outer paper layer 6 has a front side paper 7 and a back side paper 8. The left side of the front side paper 7 and the back side paper 8 are connected front to back. The right side of the front side paper 7 and the back side paper 8 are connected front to back. The lower side of the front side paper 7 and the back side paper 8 are connected front to back. The upper side of the front side paper 7 and the back side paper 8 has a hole.

[0026] The inner bag 2 is arranged in the outer bag 1. The upper opening of the inner bag 2 corresponds to the hole on the upper side of the outer bag 1 to form a bag opening structure of the paper bag.

[0027] The shock-absorbing paper bag has an inner bag 2 structure. The inner bag 2 is formed by folding an inner paper composite material 3 (including a shock-absorbing paper layer 4 and a support paper layer 5) in the shape of a flattened paper tube with an upper opening and a lower opening. The inner bag 2 is arranged in the outer bag 1. The structure of the inner bag 2 not only has a shock-absorbing function, but also is in the shape of a flattened paper tube with an upper opening and a lower opening. The connection strength and support force of the left and right sides are relatively good, so that the connection strength and support force of the left and right sides of the entire paper bag are relatively good.

[0028] The following optimizations or further descriptions can be made based on the above embodiments.

[0029] For example, the shock-absorbing buffer paper layer 4 adopts a grid-stretching paper or a bubble paper, which is a mature technology and will not be described here. In addition, the shock-absorbing buffer paper layer 4 can be connected with the supporting paper layer 5 by gluing to form an inner paper composite material 3 with relatively more stable structure.

[0030] The inner paper composite material 3 is wound at least one turn. For example, according to requirements, the inner paper composite material 3 is wound two turns, three turns, four turns, five turns, or the like. The inner bag 2 has a multi-layer winding structure, which further enhances the shock-absorbing buffer capacity and the connection strength and supporting force of the left and right sides of the inner bag 2 are relatively good, and the articles placed in the inner bag 2 are not easy to break the left and right sides.

[0031] For example, the outer paper layer 6 adopts a paper folding to form the front side paper 7 and the back side paper 8. One paper is folded to form the front side paper 7 and the back side paper 8, the folding edge 9 is the lower side edge of the front side paper 7 and the back side paper 8, the front side paper 7 and the back side paper 8 are connected front and back at the folding edge 9, and the front side paper 7 and the back side paper 8 can be connected front and back at the left side and the right side, respectively, by gluing to form a sealing edge. Or for example, the front side paper 7 and the back side paper 8 are connected front and back at the lower side, the left side, and the right side, respectively, by gluing to form a sealing edge, forming the outer bag 1.

[0032] In addition, the outer side of the inner bag 2 and the inner side of the outer bag 1 are connected by gluing to stabilize the inner bag 2 in the outer bag 1. For example, the upper opening outer side of the inner bag 2 and the inner side of the upper side of the outer bag 1 are connected by gluing, which does not easily affect the shock-absorbing buffer function.

[0033] The lower opening (lower end port of the flattened paper tube) of the inner bag 2 is closed by gluing front and back; or the lower opening of the inner bag 2 is in an open state and is closed by the outer bag 1, and the inner bag 2 is closed by the lower side of the outer bag 1. The inner side of the inner bag 2 is the supporting paper layer 5, which is relatively more flat. Generally, the supporting paper layer 5 adopts a flat paper, which is convenient for placing articles.
