Abstract

Provides a packaging method for aqueous liquid materials whereby a molded container in which an aqueous liquid material has been sealed can be packaged simply by sealing it within a packaging container of an oxygen-absorbent multilayer material provided with an oxygen layer, without the addition of moisture, and whereby oxygen present within the packaging container can be removed to maintain the aqueous liquid material in an oxygen-free state. The method involves sealing a polyolefin or vinyl chloride molded container in which an aqueous liquid material has been sealed within an outer packaging container comprising a packaging container of an oxygen-absorbent multilayer material provided with an oxygen-absorbent layer which contains an iron oxygen absorbent with high oxygen absorption capabilities consisting of iron powder coated with a metal halide, and an alkaline earth metal oxide.
