Abstract

To provide a method for transporting thermoplastic resin vials under sterile conditions and in an exogenous pyrogen-free state, introducing the vials into a filling assembly line, and thereafter allowing the vials to stand without tipping or dropping them, the method is a method for packing vials for filling with contents such as medicaments or cells by vacuum-packing the vials, and includes the following steps: (I) inserting a plurality of vials in a tray with opening portion sides of the vials facing a bottom of the tray, (II) installing a soft film on bottom portions of the vials, (III) introducing the tray having the vials installed therein and the soft film into a gas-impermeable flexible film bag, (IV) depressurizing the inside of the flexible film bag to a prescribed vacuum pressure, and (V) sealing an opening of the flexible film bag.
