ABSTRACT:
A flexible, thin wall, multi-layer plastic film pouch having an open end and possessing high strength resistance against being manually torn or stretched. A portion of the pouch, extending to the open end, projects upwardly through a substantially rigid annular flange. The end portion, being mechanically stretched outwardly and downwardly over the annular flange, fits tightly over, around and beneath the flange. The pouch is secured to the flange without further means of attachment. Thus, with the pouch being secured to the flange, the end portion provides the pouch with a substantially rigid brimmed annular opening that facilitates storage, aggressive handling and use of existing filling and closure equipment for filling and closure of the pouch.
