This invention concerns a ream wrap package formed by wrapping a sheet of polymeric film (21) around a stack of paper, the sheet having been severed from a web of polymeric film having at least one line of weakness formed therein in the machine direction (MD) and within a region of the transverse direction (TD) the package being formed by wrapping the sheet around the stack of paper to form a rectangular tube with sides overlapping, sealing one side to the other to form a girth seal (24), closing the tube at each end to form an envelope seal with tucked in ends and overlapping flaps (25,25',26,26'), at least one of which is trapezoidal, so that in the formed package there is at least one line of weakness (27) extending along the whole length of a surface of the package outside the girth seal, the line of weakness being positioned so that it terminates at each end of the package within a region of the TD defined by that portion of the overlapping flaps where there are only two layers of overlapping film. |
