Process for improving the adhesion of thin films deposited by the pecvd process in virgin, recycled or combined pet packaging in any proportion and pet packaging.

摘要

Process for improving the adhesion of thin films deposited by the process PECVD PET packaging and packaging from. It is described a process for improving the adhesion of thin films deposited by the process PECVD PET packaging which comprises applying to said package with oxygen plasma treatment and postPrevious application of film of PECVD.Treatment with plasma, aims to promote the incorporation of functional groups, increase the surface roughness and promote the binding of film to be deposited.So it will be improved the adhesion between the package and the film of carbon to be deposited.The plasma hydrogenated amorphous carbon is produced with acetilenolargu00f3nio gases using a system that consists of a vacuum chamber or reactor (1) provided with electrodes (2a...2b) connected to a source (6) of electrical voltage for generating the plasma, glow discharge plasma is produced in the chamber (1) and acting on the substrate (3),A pumping system (5) for the production of a vacuum in the chamber (1), a gas supply system (4) to the chamber.The plasma being generated by the application of an electric field continuously between the electrodes (2a, 2b) in the precursor gases at low pressure.The PET packaging with improved adhesion to the film of carbon is also described.
