Abstract
A resinous film at least partially formulated from a recycled resin and containing a vapor phase corrosion inhibitor. One embodiment of the invention is a single layer film which is formulated from three components. The first component is a recycled resin such as polyethylene, the second component is a fresh resin identical to the first, and the third component is a vapor phase anti-corrosion agent. Multi-layer films are also included. The films emit the anti-corrosion agent over a period of time to thereby protect items encased by the film.
Claims29
A single layer resin film formulated from a resinous first component comprising a post-consumer recycled plastic, a resinous second component comprising an original, non-recycled plastic resin identical in composition to the recycled plastic resin, and a vapor phase anti-corrosion third component embedded within the resin film and being deposited upon the surface of a silica gel particulate substrate.
A single layer resin film formulated from a resinous first component comprising a post-consumer recycled plastic, a resinous second component comprising an original, non-recycled plastic resin identical in composition to the recycled plastic resin, and a vapor phase anti-corrosion third component embedded within the resin film and being deposited upon the surface of a silica gel particulate substrate;
- (a) wherein said third component comprises a mixture by weight of from about 22% to about 27% sodium nitrite, from about 4% to about 6% benzotriazole, and from about 65% to about 85% anhydrous molybdate selected from the group consisting of sodium molybdate, ammonium dimolybdate, amine dimolybdates, and mixtures thereof;
- (b) wherein the vapor phase anti-corrosion third component is deposited on said silica gel particulate substrate.
A single layer resin film formulated from a resinous first component comprising a post-consumer recycled plastic, a resinous second component comprising an original, non-recycled plastic resin identical in composition to the recycled plastic resin, and a vapor phase anti-corrosion third component embedded within the resin film and being deposited upon the surface of a silica gel particulate substrate;
- (a) wherein said third component comprises a mixture by weight of from about 22% to about 27% sodium nitrite, from about 4% to about 6% benzotriazole, and from about 65% to about 85% anhydrous molybdate selected from the group consisting of sodium molybdate, ammonium dimolybdate, amine dimolybdates, and mixtures thereof;
- (b) wherein the vapor phase anti-corrosion third component is deposited on said silica gel particulate substrate;
- and
- (c) wherein the third component comprises by weight a mixture of about 68% cyclohexylamine benzoate, about 10% ethylamine benzoate, about 20% dicyclohexylamine nitrate, and about 2% benzotriazole.
A double layer laminated resin film comprising first layer formulated from a recycled plastic and a second layer formulated from an original, non-recycled plastic resin, with the second layer having contained therein a vapor phase corrosion inhibitor.
A double layer laminated resin film comprising a first layer formulated from a recycled plastic and a second layer formulated from an original, non-recycled plastic resin, with the second layer having contained therein a vapor phase corrosion inhibitor;
- (a) wherein the corrosion inhibitor component comprises a mixture by weight of from about 22% to about 27% sodium nitrite, from about 4% to about 6% benzotriazole, and from about 65% to about 85% anhydrous molybdate selected from the group consisting of sodium molybdate, ammonium dimolybdate, amine dimolybdates, and mixtures thereof;
- (b) wherein said corrosion inhibitor component is embedded within the resin film and being deposited upon the surface of a silica gel particulate substrate.
A triple layer laminate product wherein the layers comprise in order:
- (a) a first layer comprising a resinous first component comprising a recycled plastic, a resinous second component comprising an original, non-recycled plastic resin having a composition identical to the recycled plastic, and a vapor phase anti-corrosion third component;
- (b) a second metallic layer;
- and
- (c) a third resin film layer formulated from a biaxially oriented polyethylene terephthalate.
