An assembly for 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 assembly comprising:
- at least one adhesive printing station for printing an adhesive on a web in register with portions of the web forming at least one of the opposing side edges of the sleeve blank and the bottom edge of the sleeve blank;
- a blank cutting station for cutting the sleeve blank from the web;
- and
- a container forming station for wrapping the sleeve blank around the bottom blank, wherein the printed adhesive in register with the at least one of the side edges forms a seam seal between overlapping side edges of the wrapped sleeve blank and the printed adhesive in register with the bottom edge of the sleeve blank forms a bottom seal between overlapping portions of the sleeve blank and the bottom blank;
- wherein the at least one adhesive printing station is provided upstream of the container forming station such that the adhesive is printed on portions of the web forming the sleeve blank prior to the sleeve blank being provided to the container forming station.
