ABSTRACT:
A continuous form paper has a plurality of sheets which are bifolded along perforated fold lines. At the top of each sheet and at the bottom of each sheet and in parallel with the fold lines are perforated tear lines. These tear lines create a pull tab when the sheets are bifolded into a stack. The pull tabs facilitate the separation of a relatively large stack of sheets into individual sheets by tearing along the perforated bottom tear line of a preceding sheet which is in parallel alignment with the top tear line of a following sheet.
