13 . The method of claim 1 , where in the series of perforations and gaps there-between of uncut bag material comprise a shape, wherein the shape includes two substantially parallel lengths joined at adjacent ends to form a non-linear shape having both a concave region between the two substantially parallel lengths.
14 . The method of claim 13 , wherein the shape is an elongated tombstone.
15 . A method of assembling a resealable label onto a panel of bag material comprising the steps of
providing a resealable label, the label comprising a top layer and a bottom layer,
providing a panel of bag material, the panel of bag material comprising at least one layer of woven plastic,
perforating the panel of bag material to create a series of perforations and gaps there-between of segments of uncut bag material, wherein the series of perforations and segments of uncut bag material there-between comprise a shape, wherein the shape includes two substantially parallel lengths joined at adjacent ends to form a non-linear shape having both a concave region between the two substantially parallel lengths, wherein the segments of uncut bag material on one parallel length of the series are staggered relative to those on the other parallel length of the series,
adhering the bottom layer of the label to the panel of bag material such that the opening of the label for the first time causes the breaking of the segments of uncut bag material.
16 . The method of claim 15 , wherein the bag material comprises a layer of woven oriented polypropylene (OPP) co-laminated to a layer of plastic film.
17 . The method of claim 15 , wherein the perforating the panel of bag material is achieved via the application of a cutting die to the panel, wherein the cutting die comprises a strip of metal having been bent by its length to form the shape, the strip of metal comprising a series of teeth on one side of the length of the strip, and a series of gaps along its length, the gaps having widths and defining gaps between series of teeth.
