Claims
- 1. Material for protecting products comprising a film having opposite sides and a hot melt adhesive applied to one side of said film, said adhesive including particles of a vapor corrosion inhibitor mixed in said adhesive, said vapor corrosion inhibitor emitting a corrosion inhibiting vapor protecting said product from corrosion, said film being impermeable to the vapor emitted by said vapor corrosion inhibitor, said adhesive securing a nonwoven fabric to said film, said nonwoven fabric being readily permeable to the vapor emitted by said vapor corrosion inhibitor.
- 2. Material as claimed in claim 1, wherein said particles have a maximum size of about 30 microns.
- 3. Material as claimed in claim 1, wherein said vapor corrosion inhibitor is responsive to heat to emit an increasing dose of corrosion inhibiting vapor in response to an increase in temperature.
- 4. Material as claimed in claim 1, wherein said film is a shrink/stretch film that shrinks in response to heat applied thereto.
- 5. Material as claimed in claim 4, wherein the quantity of corrosion inhibiting vapor emitted by the vapor corrosion inhibitor increases as the temperature of the vapor corrosion inhibitor is increased whereby an initial relatively large dose of vapor is emitted when the material is shrunk mound a product.
- 6. Packaging defining a volume for containing a product, said packaging comprising an inner layer and an outer layer, a hot melt adhesive securing the inner layer to the outer layer, and a vapor releasing additive in said adhesive releasing a vapor into said volume for creating a protecting atmosphere within said volume, said outer layer being a flexible film and said inner layer being a nonwoven fabric, said adhesive securing one side of the nonwoven fabric to a facing side of the film, said vapor being released from said adhesive through the nonwoven fabric and into said volume.
- 7. Packaging as claimed in claim 6, wherein said additive releases a vapor corrosion inhibitor.
- 8. Packaging as claimed in claim 6, wherein said flexible film is impervious to said vapor.
- 9. Packaging as claimed in claim 6, wherein said additive is selected from the group consisting of vapor corrosion inhibitors, static electricity removers, antioxidants, antimicrobials, acid neutralizers, acids, bases, fragrances, and color emitters.
- 10. Material for shrink wrapping articles comprising a shrinkable, stretchable film outer layer having a predetermined shrink response in response to heat applied to the film, a nonwoven fabric inner layer, a hot melt adhesive securing the inner layer to the outer layer, and a protective vapor releasing additive mixed with said adhesive, said additive releasing a protective vapor, said protective vapor passing through said nonwoven fabric for treating articles wrapped by said material.
- 11. Material as claimed in claim 10, wherein said additive releases a vapor corrosion inhibitor.
- 12. Material as claimed in claim 10, wherein said film is impervious to said vapor.
- 13. Material as claimed in claim 10, wherein said additive is selected from the group consisting of vapor corrosion inhibitors, static electricity removers, antioxidants, antimicrobials, acid neutralizers, acids, bases, fragrances, and color emitters.
- 14. Packaging defining a volume for containing a product, said packaging comprising an inner layer and an outer layer, a hot melt adhesive securing the inner layer to the outer layer, and a vapor releasing additive in said adhesive releasing a vapor into said volume for creating a protecting atmosphere within said volume, said inner layer is an inner flap of a box and the outer layer is an outer flap of said box, and said adhesive secures said flaps together.
