Each bag has a front wall, a rear wall and an upper bag opening. The bag walls of each bag are provided with centrally positioned punch-out pieces positioned opposite each other adjacent the upper bag opening. The punch-out pieces may be removed by hand to form handle grips. The punch-out pieces of each of the bags in the ones of the bay walls that are on one and the same side of all of the bags in the stack are removed. Uniting the individual bags into a single stack without additional structural members is possible, when the punch-out pieces remaining in the stack and constructed as oblong perforations are interlocked with each other.
