Referring to fig. 3, the vegetable natural tissue is preferably a luffa vegetable sponge structure 200, and the buffer layer 120 is mainly prepared by bleaching a luffa vegetable sponge structure, cutting the luffa vegetable sponge structure into a plurality of small-sized particles 12, filling the small-sized particles 12 as a filling material, preferably controlling the size of the small-sized particles 12 to be between 0.5 mm and 5mm, and then attaching the small-sized particles 12 to the first surface 110 to form a plurality of buffer units 121. The packing material filled with the small-sized particles 12 is closely arranged on the first face 110 in the horizontal and vertical directions.

Specifically, the fixing adhesives 14 are coated on the surface of the first surface 110 in a horizontal and vertical arrangement manner, and a filling material is attached to the position of each fixing adhesive 14, so as to form a plurality of buffer units 121.

When the express delivery device is used, the unit layer 11 can be used as a wrapping material to wrap the surface of an object to be delivered, so that the express delivery device has a protection effect. After the use, because first face 110 is the paper material, buffer layer 120 is natural plant tissue, can directly degrade, realizes that the environmental protection is pollution-free.

Furthermore, as the natural plant tissues are adopted as the filled buffer layer 120, the space density of the unit layer 11 is small, and the unit layer can float on the water body after being used and discarded, thereby being beneficial to recovery.

In addition, for the packaging structure 100 using the multi-layer fiber mesh structure as the buffer layer 120, the paper structure is fixed on the first surface 110 in the state of the three-dimensional mesh structure without being guaranteed during manufacturing, and only glue is coated and filled, and the paper structure is fixed by using the glue, so that the manufacturing process is simpler, requirements for equipment are met, and cost reduction is facilitated.

With reference to fig. 3 and 4, in another embodiment of the present invention, the silk melon net 200 is randomly cut to form a plurality of small particles, and then the plurality of small particles are tiled and filled onto the first surface 110 to be fixed, so that the buffer layer 120 is formed by the randomly filled small particles.
