A method of making a gas-impermeable, chemically inert container wall structure comprising the steps of providing a base layer of an organic polymeric material; conducting a pair of reactive gases to the surface of the base layer preferably by pulsed gas injection; heating the gases preferably by microwave energy pulses sufficiently to create a plasma which causes chemical reaction of the gases to form an inorganic vapor compound which becomes deposited on the surface, and continuing the conducting and heating until the compound vapor deposit on the surface forms a gas-impermeable, chemically inert barrier layer of the desired thickness on the surface. Various wall structures and apparatus for making them are also disclosed.

A method of making a gas-impermeable container wail structure comprising steps of providing a base layer of an organic polymeric material; conducting a plurality of reactive gases to the surface of the base layer, supplying enough electromagnetic energy to the gases to create a plasma which causes chemical reaction of said gases to form an inorganic vapor compound which becomes deposited on said surface; pulsing the conducting and supplying steps at a selected frequency to control the temperature and stoichiometry of the deposited vapor compound, and continuing the conducting and supplying steps until the vapor compound deposit on said surface forms a coherent, strongly adherent gas-impermeable, chemically inert barrier layer of the desired thickness on said surface.
