Abstract
A reinforced shelf filing folder having front and rear panel members connected along a fold line and a tab member connected to a first side edge of the rear panel member. Reinforcement is applied to both sides of the tab member and to the outer surface of the fold line extending onto the adjacent surfaces of the front nd rear panel members. Finally, additional reinforcement means is optionally applied to the outer surfaces of the front and rear panel members, disposed along a side portion of the rear panel member opposite the first side edge and over the fold line to a corresponding portion on the front panel member. Alternatively, the additional reinforcement can be applied to the outer and inner sides of the front panel member along the first side edge. These reinforcements increase the wear resistance and life of the folder.
