Abstract: Method for treating in an enclosure an inner surface of a container made from polymer material, in order to deposit a barrier coating there on, comprises: inserting the container into the enclosure; introducing a precursor gas into the container intended, once transformed into the plasma state, to be deposited at least partially on the inner surface of the container in order to constitute the coating; wherein the method further comprises: transforming the precursor gas into the plasma state by a combination of excitations comprising a main excitation by means of electromagnetic waves comprising microwaves, and a secondary excitation by means of an electrical discharge of alternating voltage having a frequency between 1 kHz and 15 MHz.

Abstract: The invention concerns a method for treating in an enclosure an inner surface of a container made from polymer material, in order to deposit a barrier-effect coating there, comprising: inserting the container into the enclosure introducing a so-called precursor gas intended into the container intended, once transformed into the plasma state, to be deposited at least partially on the inner surface of the container in order to constitute the coating, the method further comprising: transforming the precursor gas into the plasma state by a combination of excitations comprising a main excitation by means of electromagnetic waves of the microwave type, and a secondary excitation by means of an electrical discharge of alternating voltage having a frequency between 1 kHz and 15 MHz. The invention also relates to a device for implementing the method of the invention.

Abstract: A method and device for treating a polymer to coat the surface thereof with a barrier-effect coating. The method comprises a discharge plasma in a tetrafluoroethane-1,1,1,2. or pentafluoroethane gas. The invention also concerns a device for implementing said method for treating hollow bodies. The invention further concerns the use of such a device for treating a rigid or flexible hollow body made of HDPE.

Abstract: The invention provides a container such as a bottle or flask, made heterogeneously from a material with a barrier effect and a polymer material, characterised in that the material with a barrier effect is an amorphous carbon material with a polymer tendency which is applied as a coating on a substrate of polymer material.
