a naturally degradable plastic bag capable of fertilizing soil comprises a plastic base layer, a breathable layer, a heat insulation layer and a coated film layer, wherein the breathable layer is bonded to the surface of the plastic base layer, the heat insulation layer is bonded to the surface, away from the plastic base layer, of the breathable layer, a biodegradable layer is bonded between the breathable layer and the heat insulation layer, a coated film layer is bonded to one side edge, away from the biodegradable layer, of the heat insulation layer, a reinforcing rib layer is bonded between the heat insulation layer and the coated film layer, and metal aluminum is plated on the surface of the coated film layer.
Preferably, the heat insulation layer is a polylactic acid polymer and is made of corn and cassava as raw materials.
Preferably, the metal content of the coating layer is less than 0.02%.
Preferably, a wet glue layer is coated between the breathable layer and the plastic base layer, and the wet glue layer is a starch adhesive.
Preferably, the plastic substrate is cellulose of natural wood pulp as a raw material.
Preferably, the thickness of the plastic substrate is 0.015-0.03 mm.
Compared with the prior art, the utility model discloses an advantage lies in with positive effect:
1. the toughness and the heat-insulating property of the plastic bag are greatly improved, so that the damage of the plastic bag is reduced, and the plastic bag is more favorably used.
2. The utility model discloses simple structure has improved the biodegradable properties of plastic bag, does benefit to the health of environment more.
