Abstract

The present invention is in the field of thermoplastic films used to improve performance of windows, glazings, and other devices, and, more specifically, the present invention is in the field of films that are edge cauterized, methods of edge cauterizing such films, and windows, polymeric interlayers, glazings, and other devices comprising such films.

Claims

1. A method for sealing a layered film having a performance layer and at least one polymer layer, comprising:

installing said film on a rigid substrate, and,

edge cauterizing said film.

2. The method of claim 1, wherein said rigid substrate is a window glazing.

3. The method of claim 2, wherein said window glazing is a pane of glass.

4. The method of claim 3, wherein said window glazing comprises a polymer.

5. The method of claim 2, wherein said window glazing is disposed in a frame.

6. The method of claim 5, wherein said frame is disposed in an uninstalled window.

7. The method of claim 1, wherein said installing comprises bonding said film to said rigid substrate.

8. The method of claim 1, wherein said film comprises two layers of polyester between which is disposed said performance layer.

9. The method of claim 8, wherein said polyester is poly(ethylene terephthalate).

10. The method of claim 1, wherein said edge cauterizing is done with a soldering iron.

11. The method of claim 1, wherein said film comprises a layer of polyester and a hardcoat layer between which is disposed said performance layer.

12. The method of claim 1, wherein rigid substrate is a polymeric layer for a device display or optical filter.

13. The method of claim 12, wherein said polymeric layer is for a device display.

14. The method of claim 12, wherein said polymer layer is for an optical filter.

15. A multiple layer panel, comprising:

a rigid substrate; and

,

an edge cauterized layered film having a performance layer and at least one polymer layer disposed on said rigid substrate.

16. The panel of claim 15, wherein said rigid substrate is a window glazing.

17. The panel of claim 16, wherein said window glazing is a pane of glass.

18. The panel of claim 17, wherein said window glazing comprises a polymer.

19. The panel of claim 16, wherein said window glazing is disposed in a frame.

20. The panel of claim 19, wherein said frame is disposed in an uninstalled window.

21. The panel of claim 15, wherein said film comprises two layers of polyester between which is disposed said performance layer.

22. The panel of claim 21, wherein said polyester is poly(ethylene terephthalate).

23. The panel of claim 15, wherein said film comprises a layer of polyester and a hardcoat layer between which is disposed said performance layer.

24. The panel of claim 15, wherein rigid substrate is a polymeric layer for a device display or optical filter.

25. The panel of claim 24 wherein said polymeric layer is for a device display.

26. The panel of claim 24, wherein said polymer layer is for an optical filter.
