1. A method of forming a container from a sleeve blank and a bottom blank, the sleeve blank defined by a pair of opposing side edges and opposing top and bottom edges, and the bottom blank including a bottom wall for closing one end of the container, the method comprising:
printing a second coating of an adhesive on a sleeve blank having a first coating of the adhesive such that the second coating overlies at least a portion of the first coating, resulting in an adhesive portion having a combined thickness of the first and second coatings, wherein the adhesive portion extends along at least one of the side edges of the sleeve blank;
after printing, supplying the sleeve blank to a container forming station and wrapping the sleeve blank into a sleeve such that the side edges overlap and adhere together the overlapping side edges with the adhesive portion to form a seam seal along the overlapping side edges of the sleeve; and
securing the bottom blank to the sleeve.
