<p>A padded packaging wrapper for guarding against rust and corrosion of tinplate, for example incorporates a coating ofvolatile corrosion inhibitor (VCI) on a pliable layer of sealed-cell microcellular foam supported on a strong sheet. The VCI can be incorporated in a cohesive non-adhesive coating on the microcellular layer or directly on the microcellular layer in the absence of such cohesive coating. The effectiveness of the VCI can be further enhanced by incorporating in the wrapper a vapor barrier such as for example, aluminum foil or a film of hydrophobic polymer such as a silicone or a polyester such as Mylar (polyethylene terephthalate). A water-repellant layer can also be added. The wrapper can be made anti-static and/or opaque, and strengthened with fibers that make it almost impossible to tear.</p> |
