あっしゅくぶくろ
vacuum bag (used to make clothes, futons, etc. easier to store)
Noun
布団ふとんは嵩張かさばるので、客きゃく布団ふとんなど使用頻度しようひんどの低ひくい布団ふとんは、圧縮袋あっしゅくぶくろに入いれて圧縮あっしゅくして保管ほかんするのもいいでしょう。
Since futons are bulky, it's a good idea to compress and store futons that are used infrequently, such as guest futons, in a vacuum-sealed storage bag.
