Abstract: An adjustable, re-sealable polymeric bag for perishable food storage and non-perishable storage is disclosed. The adjustable bag comprises a traditional locking or re-sealing mechanism in addition to one or more thin bendable elements affixed to, or within, the rim of the adjustable bag such that the bag is held open when the bendable element(s) are bent or adjusted, and closed when the bendable elements are bent back to a planar configuration. These bendable elements are inserted into recesses defined by the bag or affixed directly to the interior or exterior of the bag.
