Container sealing apparatus for heat sealing a plastics web to openings of containers. The apparatus comprises a transport system for transporting containers along a pair of feed paths extending alongside one another; a sealing system through which the feed paths extend, the sealing system being adapted to seal openings of containers with the plastics web material; and pairs of unwind and wind up mandrels associated with each feed path for supporting spools of the plastics material. A web of the plastics material extends in use from a spool on the unwind mandrel to a spool on the wind up mandrel of each pair and through the sealing system, wherein each mandrel is movable between a working position in which it extends orthogonally to the transport direction and a loading position at which spools of the web material can be loaded on or unloaded from the mandrel.
