Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a quality preservative with a desiccant and deoxygenating agent being in a continuously packed fashion, causing no deterioration of its desiccating and deoxygenating performance even during long unusing period. SOLUTION: This quality preservative is so designed that a desiccant 2 and a deoxygenating agent are continuously packed through a sealed portion 4 by a laminated film made up of an air-impermeable plastic film (a) as the outer layer and air-permeable films (b), (c), (d) as the inner layers so as to prevent the respective packed atmosphere from communicating with one another. In this case, part or the whole of the air-impermeable plastic film (a) is peeled off to initiate absorption of water vapor and oxygen so as to come to desired air permeability during use.
