摘要

The method involves providing a cylindrical multi-layer shell with a liquid-tight barrier, and a layer of cardboard or paper and an inner and outer surface made of plastic. The cylindrical shell is made of a multi-layer continuous web (5), where a cylinder arm (1) is provided to form a cylindrical tube (6). An inner surface of a longitudinal edge overlaps on the outer surface of another longitudinal edge. The overlapping longitudinal edges of the cylindrical tube are welded.
