Zusammenfassung: | PURPOSE:To maintain animals and plants such as perishable foods, fruits and vegetables, flowering, foods comprising animals and plants, etc., in excellent freshness. CONSTITUTION:A material having formed an anode oxidation coating film 2, into which an intermetallic compound 3 not bonded to oxygen is dispersed, on the surface of an aluminum base 1 is used as a freshness retaining of a storage container, packaging paper, etc. Al6Fe, Si, beta-AlFeSi may be cited as the intermetallic compound 3.
