This invention relates to a method of strong/tight packaging an object in order to prepare it for shipping. Initially, a substrate is applied to an object to create a smooth surface adapted to receive a sprayable plastic thereon. Then, the sprayable plastic is sprayed onto the substrate and the object to encapsulate the object.

A method according to claim 1 wherein the sprayable plastic comprises a polyurea elastomer. 3. A method according to claim 1 wherein the substrate is applied by shrink wrapping the substrate about the object. 4. A method according to claim 1 wherein the substrate substantially completely covers the object. 5. A method according to claim 1 wherein the substrate comprises a sheet material. 6. A method according to claim 5 wherein the substrate comprises a plastic sheet. 7. A method according to claim 1 wherein the object is contaminated. 8. A method according to claim 1 wherein the object has a volume of at least about 100 ft 3 . 9. A method according to claim 1 wherein the sprayable plastic creates a water-proof encapsulation about the object. 10. A method according to claim 1 wherein the sprayable plastic is a fluid when sprayed and cures to form a rigid encapsulating skin. 11. A method according to claim 1 wherein a depth indicator is applied to the substrate or the object to facilitate spraying the plastic to a desired thickness. 12. A method of packaging an object comprising the steps of:spraying a sprayable plastic onto a surface of a pallet to create a continuous first layer of the plastic on the surface;positioning an object on the first layer of plastic on the pallet, the first layer of plastic having an outline that is at least as large as the outline of the object on the pallet;applying a substrate to the object to create a smooth surface adapted to receive a second layer of the sprayable plastic thereon; andspraying the second layer of the sprayable plastic onto the substrate to encapsulate the object. 13. A method according to claim 12 further comprising a step of applying a substrate to the surface of the pallet before spraying the sprayable plastic on the surface. 14. A method according to claim 12 wherein the substrate does not extend over the edge of the first layer of plastic, so that the edge of the first layer of plastic is left exposed, and wherein the second layer of plastic is sprayed onto the exposed edge of the first layer of plastic and forms a bond therewith. 15. A method according to claim 12 wherein the substrate extends over at least two sides of the pallet. 16. A method according to claim 15 wherein the second layer of plastic extends over at least two sides of the pallet. 17. A method according to claim 12 wherein the step of spraying the sprayable plastic onto the substrate, the object, and the pallet comprises:spraying the sprayable plastic onto the substrate and the object and allowing the sprayable plastic to cure to form a rigid skin;bonding the rigid skin to the layer of plastic on the pallet; andspraying the sprayable plastic onto the rigid skin and the pallet to encapsulate the object. 18. A method according to claim 17 wherein the rigid skin is bonded to the layer of plastic with tape.
