Abstract: A substrate in the form of a film is described for producing a corrosion inhibiting atmosphere for the storage and transport of exposed bare metal parts to inhibit rust or corrosion of the metal parts. In one form, the substrate is a co-extruded film having one layer for providing shape and form to the film when molded into a specific shape and the other layer containing a vapor corrosion inhibitor (VCI) for being admitted from the surface of the layer to form the corrosion inhibiting atmosphere. Other structures of the film are possible including triple layers and the like. The co-extruded film is formed by vacuum molding optionally with pressure forming assist to form the film into a semi-rigid or rigid shape for fitting over or enveloping the metal part to be protected.
