The invention relates to a degradable plastic environment-friendly bag. The degradable plastic environment-friendly bag comprises an environment-friendly bag body, wherein the environment-friendly bagbody sequentially comprises an outer paper material layer, a bonding layer and an inner paper material layer from outside to inside; the outer paper material layer is arranged on the outer side; theinner paper material layer is arranged on the inner side; the bonding layer is arranged between the outer paper material layer and the inner paper material layer; the bonding layer consists of gauze and a degradable starch adhesive layer coating the gauze; the inner side surface of the inner paper material layer and the outer side surface of the outer paper material layer are both coated with waterproof layers. The degradable plastic environment-friendly bag disclosed by the invention has good reliability and can be degraded, so that environmental protection is greatly reduced; in addition, byimproving a handle, the contact area of the handle is improved, so that the condition that the handle tightens hands is prevented.
