In another aspect, the method includes the step of sealing and severing a pair of overlapping web portions provided with a plurality of printed portions along a plurality of lines which traverse the printed portions and each of the corresponding unprinted portions to form a plurality of sleeves wherein each sleeve has an upper portion and a lower portion with the lower portion having a printed portion extending continuously about the exterior circumference of the lower portion of the sleeve while the upper portion is free of any printing contained in the lower portion of an adjacently formed sleeve.
