The present invention relates to a closed-head drum (10) with inserted thin-walled inliner (22) of multilayer plastic film for storing and transporting liquid or free-flowing filling materials. In order to improve the use of liners in closed-head drums, and to facilitate in particular the handling for the users such as the filling and emptying operators, so as to allow the closed-head drum (10) with liner (22) to be handled in precisely the same way as a closed-head drum without a liner, the present invention provides for the liner surface to adhere, or be adhesively bonded in a detachable manner, to the inner wall of the drum by virtue of a vacuum being created in the intermediate air space between the inner wall of the drum and liner surface and by thermal activation by means of hot air injection into the interior of the inliner.
