素早く吸収することができ、水性液体を含む物品等を開
口したまま収納することができるという効果を奏する。As described above, since the sheet-shaped water absorbing portion is provided inside so as to substantially cover the inside of the bag body, the water absorbing resin is uniformly distributed in the bag body. Therefore, in the storage bag,
For example, even if an article containing an aqueous liquid is stored, the aqueous liquid released from the article is quickly absorbed by the water absorbent resin before reaching the opening. As a result, the aqueous liquid can be quickly absorbed, and an article or the like containing the aqueous liquid can be stored while being opened.

This is a configuration in which an edge portion of a bent non-water-permeable film having a heat-fusion property is heat-sealed.
【００４５】これにより、袋体の貼着部分における水性
液体の漏れを確実に防止できるという効果を奏する。As a result, it is possible to reliably prevent the leakage of the aqueous liquid at the adhered portion of the bag body.

を奏する。As described above, since the bag body has the folded-back portion formed by folding the water-impermeable film inward at the opening thereof, the aqueous liquid released from the stored article is directed toward the opening portion. Even if it flows out, the aqueous liquid is blocked at the turnback portion. As a result, it is possible to more reliably prevent the aqueous liquid from leaking out from the opening even when the article or the like containing the aqueous liquid is stored while being opened.
