A label for application to a surface having at least one compound curve is provided. The label comprises a heat shrinkable film having an inner surface and outer surface and a layer of pressure sensitive adhesive on the inner surface of the heat shrinkable film.
1. A method of applying a label to an article, the method comprising: providing an article having a perimeter and having a surface comprising at least one compound curve;providing a label comprising (i) a heat shrinkable film having an inner surface and an outer surface; and (ii) a layer of pressure
1. A method of applying a label to an article, the method comprising: providing an article having a perimeter and having a surface comprising at least one compound curve;providing a label comprising (i) a heat shrinkable film having an inner surface and an outer surface; and (ii) a layer of pressure sensitive adhesive on the inner surface of the heat shrinkable film, wherein the label has a first edge and a contact region;contacting the adhesive layer in the contact region of the label with the article;applying heat and pressure simultaneously to the label in a direction from the contact region to the first edge such that the first edge of the label adheres to the article and the label shrinks to conform to the compound curve of the article;wherein the label adheres to less than half the perimeter of the article at a given cross-section. 2. The method of claim 1 wherein heat and pressure are applied by a walking beam comprising a heated bladder. 3. The method of claim 1 wherein heat and pressure are applied by a walking beam comprising a heated cavity wherein the shape of the cavity corresponds to the shape of the article to which the label is applied. 4. The method of claim 1 wherein heat and pressure are applied by a walking beam comprising a flexible heated membrane suspended between at least two frame members. 5. The method of claim 1 wherein heat and pressure are applied by a walking beam comprising a flexible heated membrane mounted to a rectangular frame. 6. The method of claim 1 wherein heat and pressure are applied by a walking beam comprising a flexible heated membrane mounted to a frame having a shape corresponding to the shape of the article to which the label is applied. 7. The method of claim 1 wherein heat and pressure are applied by a walking beam comprising a flexible porous mesh suspended between at least two frame members. 8. The method of claim 1 wherein heat and pressure are applied by a flexible, expandable heated membrane. 9. The method of claim 1 wherein the label is provided with a release liner adhered to the adhesive layer and the method further comprises separating the release liner from the label prior to contacting the label with the article. 10. The method of claim 1 wherein the label is heated to a temperature of at least 40° C. 11. The method of claim 1 wherein the heat shrinkable film comprises a film selected from polyester, polyolefin, polyvinyl chloride, polystyrene, polylactic acid, copolymers thereof and blends thereof. 12. The method of claim 1 wherein the heat shrinkable film comprises a polyolefin. 13. The method of claim 1 wherein the heat shrinkable film comprises a multilayer film having a core layer and at least one skin layer. 14. The method of claim 1 wherein the stiffness of the film is at least 5 mN in the machine direction. 15. The method of claim 1 wherein the label further comprises a print layer between the heat shrinkable film and the adhesive layer, wherein the heat shrinkable film is transparent. 16. The method of claim 1 wherein the label further comprises a print layer on the outer surface of the heat shrinkable film. 17. The method of claim 16 wherein the label further comprises a protective layer overlying the print layer. 18. The method of claim 1 wherein the adhesive layer comprises an emulsion adhesive. 19. The method of claim 1 wherein the adhesive layer comprises a hot melt adhesive. 20. The method of claim 1 wherein the adhesive layer comprises a solvent based adhesive. 21. The method of claim 1 wherein the pressure sensitive adhesive layer is continuous. 22. The method of claim 1 wherein the pressure sensitive adhesive layer is patterned and the pattern substantially covers the inner surface of the film wherein the pattern is continuous over the film surface. 23. The method of claim 1 wherein the label comprises a center and a second edge opposite the first edge, and the contact region is proximate to or in the center of the label. 24. The method of claim 1 wherein the label comprises a second edge opposite the first edge and the contact region is proximate to the second edge of the label. 25. The method of claim 1 wherein heat and pressure is applied by a heated conformable membrane.
