ABSTRACT:
A flexible bag construction and a method for producing the bag. The construction is formed from flexible plastic films located in overlying relationship with one film defining a return portion having a free edge positioned inwardly from the top of the bag. A second free edge is defined by a separate film portion in spaced relationship relative to the first free edge. A flexible plastic strip is introduced between the return portion and the opposing film and this strip is heat sealed in place. The second free edge provides a means for inserting articles into the bag whereby the bag can be used for merchandising purposes, particularly after being sealed along the second free edge. An opening is preferably formed in the top of the bag extending through overlying film portions and the intermediate strip to provide means for suspending the bag.
