Water-absorbing degradable plastic bag

Abstract

The invention provides a water-absorbing degradable plastic bag. The bottom of the plastic bag comprises a surface wrapping layer, a water-absorbing core layer and a plastic bag body from inside to outside, wherein four edges of the surface wrapping layer are bonded with the plastic bag body by means of heating. As a highly water-absorbing resin layer is added to the bottom of an existing plastic bag and fixed to the bottom of the plastic bag through the surface wrapping layer, waste water in plastic flows down along the wall of the bag under the action of gravity, and is accumulated at the bottom of the bag and absorbed by the water-absorbing core layer, so that the whole plastic bag is kept dry, and food waste contained in the plastic bag is not easy to deteriorate and stink. Besides, by the aid of the added water-absorbing core layer and the surface wrapping layer, the bottom of the plastic bag, mainly used for bearing, is firmer and not easy to be damaged. The plastic bag body made of polyethylene modified materials can be naturally degraded, so that white pollution is reduced.
