Abstract
A durable binder for holding papers and the like includes exterior and interior cover sheets that are attached to each other by heat sealing to define relatively rigid panels separated by hinge panels. The hinge panels are each characterized by a multitude of minute separate depressed areas in which the cover sheets are connected, the depressed areas being surrounded by intersecting raised areas. The depressed areas can be of varying depth and can define pockets for holding writing instruments and other objects.
