ABSTRACT:
A plastic film bag with overlying front and rear bag walls, the upper edges of which define a bag mouth. Pleats defined in each bag wall extend vertically downward from the mouth-forming edges. The pleats, upon expansion by direct finger engagement therewith or the application of outwardly directed opposite forces on the opposed ends of the mouth portion of the bag, cause a lateral separation of the edges for initiating opening of the bag mouth. The bag may be vertically partitioned into lateral compartments with at least one wall of each compartment including a mouth-opening pleat therein.
