PROBLEM TO BE SOLVED: To disclose a production method of a leafy vegetable packaging body capable of holding the freshness of leafy vegetables over a long period of time.SOLUTION: A production method of a leafy vegetable packaging body includes: a first step of closing an opening of the other side rather than a storage position of leafy vegetables among openings of cylindrical packaging films a second step of receiving the leafy vegetables from the opening end of the one side of the cylindrical packaging film to the inside space of the cylindrical packaging film a third step of closing the opening of the one side rather than the storage position of the leafy vegetables among the openings of the cylindrical packaging films after the first step and the second step. The production method of the leafy vegetable packaging body is characterized in that inert gas is supplied at a line speed of 1 m/sec or more and 4 m/sec or less into a space of the inside of the cylindrical packaging film through the piping while inserting piping from the opening end of the one side of the cylindrical packaging film to the inside of the cylindrical packaging film, at least in an interval before starting the third step after completing the first step.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】葉物野菜の鮮度を長期間に亘って保持可能とする、葉物野菜包装体の製造方法を開示する。【解決手段】筒状の包装フィルムの開口のうち前記葉物野菜の収容位置よりも他方側の開口を閉じる、第1工程と、前記筒状の包装フィルムの一方側の開口端から該筒状の包装フィルムの内側の空間へと葉物野菜を収容する、第2工程と、前記第1工程及び第2工程の後で、前記筒状の包装フィルムの開口のうち前記葉物野菜の収容位置よりも一方側の開口を閉じる、第3工程と、を備え、少なくとも前記第1工程を完了した後から前記第3工程を開始するまでの間において、前記筒状の包装フィルムの前記一方側の開口端から前記筒状の包装フィルムの内側に配管を挿入した状態で、該配管を介して前記筒状の包装フィルムの内側の空間に1m/sec以上4m/sec以下の線速度にて不活性ガスを供給することを特徴とする、葉物野菜包装体の製造方法とする。【選択図】図2
