<p>A package bag may be made from a sheet of flexible packaging material that has been folded along a longitudinal direction with the edges of the sheet brought together and sealed to form a longitudinal rear seam. A starter cut has been formed only in the longitudinal seam to facilitate opening the package bag. The package bag may be opened by pulling in opposite directions on the longitudinal seam at points on either side of the starter cut. Such package bags may be made from a sheet of flexible roll stock having one or more notches formed at spaced apart locations along one or more edges of me sheet. When the sheet is folded such that the edges meet and are sealed to form a longitudinal rear seam of a package bag, the notches provide a starter cut for opening the package bag.</p> |
