Zusammenfassung:	To obtain a functional film capable of efficiently adsorbing and decomposing ethylene, a functional container, and a method for retaining the freshness of plants or foods. This functional film is obtained by causing a substance having a catalytic ability to decompose ethylene to be contained in, or applied or vapor-deposited on the surface of, a plastic film material having an ethylene-adsorbing effect. This functional container is obtained by causing a substance having a catalytic ability to decompose ethylene to be contained in, or applied or vapor-deposited on the surface of, a plastic material having an ethylene-adsorbing effect. Alternatively, this functional container may be obtained by causing a substance having a catalytic ability to decompose ethylene to be contained in a plastic material having an ethylene-adsorbing effect and molding the plastic material into a prescribed shape, or by applying or vapor-depositing the substance on the surface of the plastic material after molding said plastic material into a prescribed shape. This method for retaining freshness includes a step for adsorbing and decomposing, and/or discharging, the ethylene generated from plants and the like using said functional film or said functional container.
