ABSTRACT:
A bag including first and second walls having joined first and second opposed side edges, and an end edge and at least one seal line spaced from the end edge and extending laterally from one side to the other for sealing closed the end of the bag. In combination with the bag is the improvement comprising an easy-open corner portion of the bag. The corner includes a cut formed in both side walls closer to one side edge than the other and communicating with the end edge of the bag and extending towards the spaced-apart seal line, and a plurality of closely spaced-apart perforations in both side walls extending in a line from within close proximity of the cut to the closer side edge and forming a tear line for permitting a portion of the side walls, including a portion of the end edge of the bag, to be torn away from the bag in a progressive tearing motion to form a hole in the bag from which the contents can be poured without interference from a remaining portion of the end edge of the bag.
