摘要

System and method for manufacturing a plastic container coated with a barrier against gas, method for packaging a beverage, drink packaged system for packaging a beverage, and,The coated plastic container. Methods and systems are provided for the manufacture of a plastic container coated with barrier (102), e.g. for drinks packaging.The system comprises a vacuum cell.A source of coating (106) in the cell to provide a vacuum steam coating to an external surface of a plastic container (102) positioned within the vacuum cell and feedsGas (115) for supplying one or more process gases in an internal space of the vacuum cell.The source of coating heats and evaporates a material of inorganic coating (108), such as metal or silicon, to form a vapor coating that is energized to form a plasma.The gases from the process include a carbon containing gas such as acetylene.The steam and / or plasma coating react with at least one of the gases from the process and a thin coating is deposited and attached on external surface of the plastic container.In the thin coating comprises carbon and inorganic material, for example, an inorganic oxide.
