ABSTRACT:
A polyester pocket with a clear front and back is provided. A spun-bonded polyester strip is positioned near the open end of the polyester pocket to prevent atmospheric contaminants from entering the polyester pocket. The spun-bonded polyester strip also allows the polyester pocket to lay flat when multiple polyester pockets are stacked upon one another. The thickness of the spun-bonded polyester can be made to roughly correspond to the thickness of documents inserted into the polyester pocket.
