The invention concerns the use of a composition or premix based on volatile corrosion inhibitors comprising, in order to limit to a maximum the release and/or degradation of the volatile corrosion inhibitors when the composition or premix is being formed, either an efficient amount of a structuring agent consisting of at least one solid or pasty substance whereof the melting point ranges from 40 to 110° C. preferably from 50 to 90° C., or a liquid substance capable of forming, mixed with a mineral filler, a solid or pasty combination. The invention also concerns a composition based on volatile corrosion inhibitors comprising a composition based on volatile corrosion inhibitors comprising an efficient amount which contains an efficient amount of a solid structuring agent. The invention further concerns polymer based articles having as constituent said composition or premix; said article are useful for protecting metal parts against corrosion.

1. A packaging article, comprising a premix and a component, wherein the component is selected from the group consisting of at least one polymer and at least one filler, wherein:said at least one polymer represents at least 50% by weight of the packaging article and is selected from the group consisting of: polyolefins, such as polyethylene, polypropylene, polybutene and copolymers thereof with one or more unsaturated monomers such as vinyl acetate, acrylic acid and esters thereof formed from short chain alcohols; polyvinyl chloride and copolymers thereof, acrylic copolymers and derivatives thereof; polyamides, polystyrenes, polycarbonates, polyesters, polyurethanes, rubbers such as natural rubber, styrene-butadiene and polychloroprene;said at least one filler is selected from the group consisting of mineral fillers such as chalks and carbonates, talcs, clays and silicas; and,said premix comprises volatile corrosion inhibitors and at least one structuring agent which is a mineral wax or a polyethylene wax selected from the group consisting of a solid or pasty substance and a liquid substance being capable of forming, when mixed with a mineral filler, a pasty or solid substance; said solid or pasty substance being selected from the group consisting of solid, pasty, aliphatic and resinous compounds with a low melting point of between 40° C. and 110° C., the amount of structuring agent being effective to reduce the release of said volatile corrosion inhibitors when said packaging article or premix is formulated as compared to formulating premix in the absence of the structuring agent. 2. The packaging article according to claim 1, wherein the packaging article consists of single films or of assemblies of several elements, said assemblies being produced by employing any suitable method including stapling, crimping, thermoforming, skin-packing or the manufacture of blisters. 3. The packaging article according to claim 1, wherein the premix comprises from about 1% to about 80% by weight of at least one volatile corrosion inhibitor and about 20% to about 99% of at least one structuring agent consisting of a solid or pasty substance having a melting point of from about 40° C. to about 110° C. 4. The packaging article according to claim 1, wherein the solid or pasty structuring agent is selected from the group consisting of linear and/or only slightly branched mono- or polyfunctional aliphatic compounds with hydrocarbon chains having at least 10 carbon atoms. 5. The packaging article according to claim 1, wherein the structuring agent is selected from the group consisting of: linear and/or only slightly branched alipliatic hydrocarbons, such as parades and isoparaffins; polyolefins and copolymers thereof with low molecular masses of 3,000 to 20,000 g/mole. 6. The packaging article according to claim 1, wherein the structuring agent is a resinous compound having a polymeric and/or cyclic structure and which may contain, in a minor proportion, aromatic derivative and cyclic terpenes. 7. The packaging article according to claim 1, wherein the premix comprises at least one volatile corrosion inhibitor selected from the group consisting of: nitrogen-containing derivatives such as, aliphatic, aromatic, acyclic or cyclic anlines, such as dicyclohexylamine, cyclohexylamine, morpholine, diisopropylamine and benzylamine, organic salts thereof, such as benzoates, carbamates, laurates, caprylates, and succinates, or inorganic salts thereof such as nitrites, nitrates, carbonates, phosphates, and phosphites; and, heterocyclic compounds such as imidazole and derivatives thereof, triazes and derivatives thereof, as well as hexamethylenetetramine; reaction products of oxido nitrogen-containing derivatives such as alkali metal or alkaline earth salts of nitrous acid which have a vapour pressure of at least 10 −5 mm Hg at 20° C. 8. The packaging article of claim 1, wherein the solid or pasty aliphatic and/or resinous com pound has a melting point of between 50° C. and 90° C. 9. The packaging article according to claim 1 having a form selected from the group consisting of films which are retractable, flexible or rigid, wires, tubes, sheets, or pasty solids with a plastic character. 10. The sheets according to claim 9, wherein the sheets define a space between the sheets and the space is in a form of cells. 11. The packaging article of claim 1, wherein the premix comprises from 20% to 60% by weight of at least one volatile corrosion inhibitor. 12. The packaging article of claim 1, wherein the premix comprises from 40% to 80% of at least one structuring agent. 13. A process for producing the packaging article of claim 1 made of polymeric material comprising the steps of:preparing the premix; and,subsequently incorporating said premix in the polymer. 14. A process for producing the packaging article of claim 1 in the form of a pasty solid with a plastic character comprising preparing a formulation by mixing in one step the constituents of the premix with the filler. 15. A process for protecting metal parts against corrosion comprising the steps of:forming a cavity in the packaging article of claim 1; and,placing the metal parts in said cavity. 16. A process for protecting metal parts against corrosion comprising the step of bringing the pasty solid packaging article of claim 1 having a plastic character into a form adapted to dimensions of the metal parts to be protected against corrosion.
