ABSTRACT:
A flexible package is provided with a shrouded slider fastener closure. The slider traverses fastener tracks which extend across the width of the flexible package, including side seals which form the side margins of the package. The film forming the front and real panels of the flexible package extends over and above the fastener tracks and slider, forming an upper shroud portion. A line of weakness is formed in the plastic film below the fastener tracks and a cut line immediately adjacent a side seal of the flexible package intersects the line of weakness so as to propagate a tear opening thereto. The cut line either extends to the side edge of the flexible package or an opening in the form of a tear notch, for example, is located in the side seal to initiate tearing with propagation to the cut line. In this manner, tension relief is provided for the plastic film while allowing the slider to remain substantially enclosed.
