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.

Agricultural container

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 &#x3bc;m or more and 100 &#x3bc;m or less, and is formed of cellulose acylate including an ester oligomer or a sugar ester derivative.

Formed body

Objects of the present invention are to provide a film for an agricultural greenhouse that can maintain a COconcentration 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&#xb0; C., a relative humidity of 80% and a thickness of 60 to 200 &#x3bc;m.
