The anticorrosive plastic packaging materials for protecting iron, aluminum and alloys of these metals against corrosion comprise synergistic mixture of contact-vapour phase corrosion inhibitors containing salt or salts selected from the salts of ammonium and alkali metals or alkaline-earth metals derived from benzoic acid and for nitrous acid and 1,3-benzodiazole and for its 1-methyl derivative and 1H-benzotriazole and/or its methyl derivative and amorphous silicium oxide.As the anticorrosive plastic packaging article are predominantly used films or packaging products made of film, containers, either of mono- or multi-layer construction, wherein in case of multilayer packaging articles the synergistic mixture of contact-vapour phase inhibitors is with advantage added to the layer or layers closer to the article to be protected.
