VACUUM STORAGE BAG

摘要

A vacuum storage bag providing an interior volume for storing food items in an evacuated condition has air flexible sidewalls made of a gas permeable material. The gas permeable sidewalls can be made of multiple layers including a heat sealing innermost layer and a relatively stronger, outwardly disposed gas permeable layer. The heat sealing layer can be low density polyethylene to facilitate forming of the bag with heat seals and the stronger gas permeable layer can be high density polyethylene to provide the bag with sufficient strength and toughness. In various embodiments, the storage bag can include interlocking closure strips for releasably closing an opening, a one-way vacuum valve for evacuating the interior volume, and a textured portion along one sidewall to facilitate evacuation.
