Abstract
A carton filled with a chain of interconnected open bags arranged in a plicated array is disclosed. A process for filling the carton is disclosed in which the chain of bags is fed into an inverted container, closed end first, with the bags being laid in horizontal layers. Each layer is folded back on the preceding layer to produce a plicated array. At the completion of carton loading, the trailing edge of the web preferably is fed along one end wall of the container and out an opening near or at what will become the top of the container. The container is then closed and inverted. The first bag in is the first bag out and it is positioned adjacent to a dispensing opening. The last bag in, which will be the last bag out, also projects exteriorly of the carton and is fixed in place as by taping it to the side of the carton. The plicated array has alternate folds spaced inwardly from the ends of the container.
