One or more additional sidewalls may be disposed within the bag, and these additional sidewalls may be connected to form an inner bag. Any inner bag sidewalls may be laminated to the outer bag sidewalls or hang loose from the outer bag sidewalls. One or more of the sidewalls may include an adhesive for adhering to an opposing sidewall or item in the bag, a thin perforated layer disposed over an adhesive, a line of perforations for tearing, and/or one or more perforations for venting. Furthermore, processes for manufacturing a storage bag are disclosed.
