The invention discloses a degradable environment-friendly type tough express bag body. The degradable environment-friendly type tough express bag body comprises an express bag body which is made of adegradable material, wherein the side wall of the express bag body is glued with a first transverse plate and a second transverse plate which are arranged in the horizontal direction; the first transverse plate is positioned above the second transverse plate; opposite sides of the first transverse plate and the second transverse plate are provided with guide slots; a tag board is arranged betweenthe first transverse plate and the second transverse plate; upper and lower ends of the tag board are separately positioned in the two guide slots; the tag board can freely move between the two guideslots; one end of the tag board is fixedly connected with a baffle plate; and a placing slot is formed in the side wall of the first transverse plate. The degradable environment-friendly type tough express bag body can be prepared by a biodegradable cassava starch material and biodegradable sisal fibers; and wear resistance and corrosion resistance of the sisal fibers are comprehensively utilized,and polyethylene is added, so that load-bearing pressure of the express bag body can be effectively improved, and therefore, the degradable environment-friendly type tough express bag body can be repeatedly used and carried.
