Abstract An internally lined food storage bag useful in the storage of moisture-retentive foods such as fruits and vegetables. The storage bag comprises a hand-closed water-impermeable outer bag containing an absorbent inner bag. The inner bag is made of water absorbent paper or paper-like material attached at the bottom and in small areas (i.e., spots) only part of the way up the interior of the outer bag, thereby enabling separate closure.
