摘要： The agricultural material includes a cellulose acylate layer and a polymer layer. The cellulose acylate layer is formed of cellulose acylate. The polymer layer is provided on a first CA surface, which is one surface of the cellulose acylate layer. The polymer layer has a moisture permeation resistance of at most 7.5×10−4 m2·day/g per 1 μm of thickness and is formed of a polymer different from cellulose acylate. The agricultural material has a tear strength of at least 0.10 N.

摘要： Objects of the present invention are to provide a film for an agricultural greenhouse that can maintain a CO2 concentration necessary for the photosynthesis of plants even when ventilation is not performed and to provide an agricultural greenhouse using the film. The film for an agricultural greenhouse of the present invention is a cellulose film which contains a cellulose acylate resin and has an equilibrium moisture content of 4% to 8% at a temperature of 25° C., a relative humidity of 80% and a thickness of 60 to 200 μm.
