    摘要: A method and apparatus for producing an improved easy-open container wherein a continuous base layer is integrally extruded with structure for gripping thereon and applied to existing film to seal perforated lines of tearing therein. Interlocking zipper elements are contemporaneously extruded and fused to the continuous base layer. Die clutter is reduced and the method produces a flexible container having desirable sealing, opening and gripping features.
