<P>PROBLEM TO BE SOLVED: To develop a package of a freeze storage container which prevents damage to a housed freeze storage container even when preserved at a very low temperature of -80 to -196°C using a conventional freeze storage container, and is excellent in heat sealability. <P>SOLUTION: A method of using the package of the freeze storage container at the very low temperature of -80 to -196°C, is disclosed. The use method includes a step of housing the freeze storage container in the package. The package comprises a laminated film including at least an adhesive fluoropolymer film and a film other than the adhesive fluoropolymer film, wherein the adhesive fluoropolymer film is present on at least one outermost surface. The adhesive fluoropolymer film is made of an adhesive fluoropolymer having an adhesive site, wherein the at least one adhesive site is selected from a group consisting of carbon-carbon double bond, carbonyl group [-C(=O)], carbonyl group-containing groups or bonds, hydroxyl group, cyano group, sulfonic acid group and epoxy group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
