ABSTRACT:
A flexible storage bag for storing food items and the like is provided with a separation material positioned to cover an aperture disposed in and/or a one-way valve element attached to the storage bag. The separation material may be a non-woven material. When latent air remaining in the interior volume of the storage bag is exhausted through the aperture and/or one-way valve element, the air passes through the separation material. The separation material functions to remove liquids that may be entrained in the exhausting air. In an embodiment, the separation material may be treated with a low surface energy substance to improve the liquid removal function. In another embodiment, the separation material may be provided as a plurality of layers or as part of the one-way valve element.
