The invention discloses a five-layer-coextrusion, high-thermal-insulation, antifogging and drip-free agricultural greenhouse plastic film which comprises the following raw materials by weight percentage: agricultural polyethylene resin (including EVA (ethylene vinyl acetute) resin), a thermal insulation agent, an antifogging agent, an antidripping agent and an ageing resisting agent. According to the agricultural greenhouse film formed by five-layer coextrusion blow molding according to a layering formula, the thermal insulation property and the usage period of the film can be improved and prolonged; the raw materials are saved; antidripping and antifogging periods are prolonged; the property of the agricultural greenhouse film is improved; the yield and quality of overwintering greenhouse vegetables, fruit trees, flowers, and the like covered with the film can be increased and improved obviously; and the film has better popularization and application prospects.
