Abstract: 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.

Abstract: A formed body includes a base material, an adhesive layer, and a cellulose acylate film. The base material is formed of a thermoplastic resin and is in the form of a transparent sheet. The adhesive layer bonds the base material and the cellulose acylate film. The cellulose acylate film has a thickness in a range of 15 μm or more and 100 μm or less, and is formed of cellulose acylate including an ester oligomer or a sugar ester derivative.

Abstract: The packaging material is formed of a laminated film having a base material containing cellulose acylate and a resin layer. The resin layer is formed on one surface of the base material and contains any one of a mixture of an acrylic resin and a cellulose derivative, a silicone elastomer, or a urethane elastomer. The packaging material is formed of the laminated film having a moisture permeability at 40° C. and a relative humidity of 90% in a range of 60 g/m2·day or more and 700 g/m2·day or less.

Abstract: 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.

Abstract: A greenhouse has a daylighting member supported by a frame. The daylighting member partitions a growing space for agricultural products from an outside world, and emits light, which has entered from a light incident surface on one side, from a light emitting surface on the other side. The daylighting member has a transparent substrate layer and a transparent light emitting layer provided closer to a light emitting surface side than the substrate layer. The light emitting layer has a refractive index of 1.54 or less, water absorbability, and an equilibrium moisture content of 10% or greater at 25° C. and a relative humidity of 80%.

Abstract: A packaging bag as an agricultural container has a film which forms a partition separating a housing space which houses agricultural products such as fruits and vegetables from an external space. The packaging bag includes a CA film and a porous film. The CA film contains cellulose acylate having an acyl group substitution degree of 2.00 to 2.97. The porous film is formed such that a plurality of pores having an average pore size of 0.0050 μm to 5.0 μm penetrate the film in a thickness direction.
