Abstract:
1. A method for packaging a cryopreservation container, which comprises producing a package by shaping a laminated film comprising at least an adhesive fluoropolymer film on at least one outermost layer and a film other than said adhesive fluoropolymer film, into a bag-like article by heat sealing at 180-250° C., packaging the cryopreservation container in the package, wherein the adhesive fluoropolymer film is made of an adhesive fluoropolymer containing at least one adhesive site, wherein the at least one adhesive site is selected from the 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, wherein the film other than the adhesive fluoropolymer film is a low-temperature resistant resin film, wherein the low-temperature resistant resin comprises at least one resin selected from the group consisting of ultrahigh molecular weight polyethylene, polyimides, polytetrafluoroethylene, ethylene-tetrafluoroethylene copolymers and ethylene-vinyl acetate copolymers.
