The invention relates to a method for treating an elastomer packaging element (10), in particular a stopper intended for a medical or pharmaceutical use, said packaging element (10) including a lower portion (11), intended for entering into a neck (21) of a container (20), and an upper portion (12), intended for engaging tightly with an upper surface (22) of said neck (21) of the container (20), the upper surface of said upper portion (12) being treated by a plasma-assisted polymerisation process at atmospheric pressure, by means of a plasma "flame" created at atmospheric pressure, in which a monomer is injected, said monomer polymerising on said upper surface so as to form a coating (18). |
