<p>A modified flexible package (10) includes a front elastomeric wall (11) and a rear elastomeric wall (12). The front wall (11) and the rear wall (12) are sealed together at a top seal (20) at a top end of the side walls. The top seal (20) is formed by applying heat and/or pressure for a given dwell period, and is preferably a de-laminating seal. A first zipper part (40-1) is attached to an inside surface of the front wall (11) and has a first engagement member (43-1) facing the rear wall. A second zipper part (40-2) is attached to an inside surface of the rear wall (12) and has a second engagement member (43-2) facing the front wall. The first (43-1) and second engagement (43-2) members are engaged together. Both the top seal (10) and the zipper engagement members (43-1, 43-2) are 'pinch grip opened'. The invention provides a re-closable package that can be opened in an easy one-step manner - 'pinch grip opening' - without an additional step of cutting, tearing or the like.</p> |
