  • Patent number: 6942414
    Abstract: A sheet protector includes a front panel and a back panel attached together to form a pocket and a margin. The pocket may have an opening extending along a top edge of the panels. The margin extends along a side of the pocket. The opening may extend a distance into the margin such that a width of the opening is greater than a width of the pocket. For example, the width of the opening may be at least about 2% greater than the width of the pocket. Alternatively, a sheet protector includes a sheet of material folded about a fold line to form the front panel and the back panel. The panels are welded together at a bottom weld line, an outer weld line located along one side, and at an inner weld line located in a spaced relationship from the outer weld line. A margin is defined between the outer and inner weld lines, and a pocket is defined between the panels and within the fold line, the bottom weld line, and the inner line, with an opening being defined along the top edges of the panels.
