A film includes a vinyl chloride-based resin, a modified epoxidized vegetable oil having a multimer mass content of 5 to 50%, an aliphatic dibasic acid ester-based compound with not more than 10 carbon atoms having a molecular weight-average of 200 to 1000, and a polyester-based compound having a molecular weight-average of 3000 to 10000, in which a mixture of the modified epoxidized vegetable oil and the aliphatic dibasic acid ester-based compound is compounded in a mass ratio of 30 to 50 parts based on 100 parts of the vinyl chloride-based resin, a content of the modified epoxidized vegetable oil in the mixture of the modified epoxidized vegetable oil and the aliphatic dibasic acid ester-based compound is 30 to 70% by mass, and the polyester-based compound is compounded in a mass ratio of 5 to 15 parts based on 100 parts of the vinyl chloride-based resin.
A film for food packaging, comprising a vinyl chloride-based resin (A), a modified epoxidized vegetable oil (B) having a multimer content of 5 to 50% by mass, an aliphatic dibasic acid ester-based compound (C) with not more than 10 carbon atoms having a weight-average molecular weight of 200 to 1000, and a polyester-based compound (D) having a weight-average molecular weight of 3000 to 10000, a mixture of the modified epoxidized vegetable oil (B) and the aliphatic dibasic acid ester-based compound (C) being compounded in an amount of 30 to 50 parts by mass based on 100 parts by mass of the vinyl chloride-based resin (A), a content of the modified epoxidized vegetable oil (B) in the mixture of the modified epoxidized vegetable oil (B) and the aliphatic dibasic acid ester-based compound (C) being 30 to 70% by mass, and the polyester-based compound (D) being compounded in an amount of 5 to 15 parts by mass based on 100 parts by mass of the vinyl chloride-based resin (A).
