PURPOSE: Provided is use of a structure for manufacturing hermetical industrial or food packaging in direct contact with a humid or aqueous medium, wherein the structure comprises at least one layer of polydimethyl ketone in direct contact with the most humid medium. CONSTITUTION: The structure for manufacturing hermetical industrial or food packaging in direct contact with a humid or aqueous medium, comprises at least one layer of polymer(A) in direct with a humid or aqueous medium, wherein the humid medium is situated in the packaging when the packaging contains water or aqueous or humid product, and the humid medium is situated out of the packaging when the packaging contains a dry product or product to be protected from humidity. The polymer(A) comprises the units(A1) and (A2), and the A2/(A1+A2) molar ratio is between 0 and 30 percent.
