Dictionary / Vocabulary / 圧縮袋
あっしゅくぶくろ
vacuum bag (used to make clothes, futons, etc. easier to store)
布団は嵩張るので、客布団など使用頻度の低い布団は、圧縮袋に入れて圧縮して保管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.
