PURPOSE:To obtain the title PVC film excellent in transparency, etc. and excellent in low-temperature strength, by mixing a vinyl chloride resin which is a mixture of at least two resins of different degrees of polymerization and has a specified average degree of polymerization with a specified amount of a crosslinking agent and forming the resulting mixture into a film. CONSTITUTION:A vinyl chloride resin which is a mixture of at least two vinyl chloride resins of different degrees of polymerization and has an average degree of polymerization in a mixed state of 1,000-1,600 is prepared by, e.g., a process comprising mixing 95-50pts.wt. vinyl chloride resin of a degree of polymerization of 1,100-1,500 with a vinyl chloride resin of a degree of polymerization of 500-1,100 and/or 5-50pts.wt. vinyl chloride resin of a degree of polymerization of 1,500-2,500. 100pts.wt. this vinyl chloride resin is mixed with 20-80pts. wt. plasticizer (e.g., dibutyl phthalate), and the resulting mixture is formed into a film to obtain the purpose agricultural flexible vinyl chloride resin film. This film can be suitably used for greenhouse cultivation in a cold district, covering materials for tunnels, etc.
