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) , to form a rectangular tube with sides overlapping, sealing one side to the other to fo rm a girth seal (24) , closing the tube at each end to form an envelope seal wi th 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 li ne of weakness (27) extending along the whole length of a surface of the packag e outside the girth seal, 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. |
