Abstract

According to various embodiments, a film assembly may include a protective film, first and second removable opposing tabs, an adhesive, and a split release liner. The first and second opposing tabs may be configured to facilitate the alignment of the protective film with respect to a surface of a portable electronic device. Once aligned, a minority portion of the split release liner may be removed exposing a minority portion of the protective film coated with the adhesive. The minority portion of the protective film may then be adhered to the surface of the portable electronic device. Subsequently, the remaining sections of the split release liner may be removed and the protective film may be fully adhered to the surface of the portable electronic device. Once fully adhered, the first and second opposing tabs may be removed.

Claims

1. A film assembly for a portable electronic device, comprising:

a protective film configured to protected a surface;

a first tab and an opposing second tab extending from the protective film configured to facilitate the alignment of the protective film with respect to the surface;

an adhesive coating an underside of the protective film configured to adhere the protective film to the surface;

a split release liner comprising a first portion and a second portion configured to selectively line the adhesive prior to adhesion;

wherein the first portion of the split release liner may be removed independently from the second portion of the split release liner; and

wherein the first and second opposing tabs are configured to be selectively removed from the protective film.

2. The film assembly of claim 1, wherein the first portion of the split release liner is a minority portion of the split release liner and the second portion of the split release liner is a majority portion of the split release liner.

3. The film assembly of claim 1, further comprising:

an applicator tool having a straight edge configured to smooth the protective film along the surface to expel air pockets.

4. The film assembly of claim 1, further comprising:

a liquid configured to be applied to the adhesive in order to facilitate aligning the protective film with respect to the surface.

5. The film assembly of claim 1, wherein the protective film comprises one of polyester, polypropylene, and polyethylene.

6. The film assembly of claim 1, wherein the adhesive comprises one of a solvent based adhesive, a polymer dispersion adhesive, an emulsion adhesive, a contact adhesive, a hot adhesive, a reactive adhesive, and a pressure sensitive adhesive.

7. The film assembly of claim 1, wherein the adhesive comprises a removable pressure sensitive adhesive.

8. The film assembly of claim 1, wherein the protective film is substantially transparent.

9. The film assembly of claim 1, wherein the second portion of the split release liner comprises at least two sections of release liner.

10. The film assembly of claim 1, further comprising a third tab extending from the protective film configured to facilitate the alignment of the protective film with respect to the surface;

and

wherein the third tab is configured to be selectively removed from the protective film following adhesion of the protective film to the surface.

11. The film assembly of claim 1, further comprising a top coating on an upper surface of the protective film.

12. A method for applying a protective film to a surface of a portable electronic device, comprising:

removing a first portion of a split release liner to expose a first portion of a protective film coated with an adhesive;

aligning the protective film with respect to a surface using first and second opposing tabs extending from the protective film;

adhering the first portion of the protective film to the surface using the adhesive;

removing a second portion of the split release liner to expose a second portion of the protective film coated with the adhesive;

adhering the second portion of the protective film to the surface using the adhesive;

removing the first and second opposing tabs extending from the protective film.

13. The method of claim 12, wherein the first portion of the split release liner is a minority portion of the split release liner and the second portion of the split release liner is a majority portion of the split release liner.

14. The method of claim 12, further comprising:

using an applicator tool to smooth the protective film on the surface to expel air pockets.

15. The method of claim 12, further comprising:

applying a liquid to the adhesive to facilitate aligning the protective film with respect to the surface.

16. The method of claim 12, wherein the protective film comprises one of polyester, polypropylene, and polyethylene.

17. The method of claim 12, wherein the adhesive comprises one of a solvent based adhesive, a polymer dispersion adhesive, an emulsion adhesive, a contact adhesive, a hot adhesive, a reactive adhesive, and a pressure sensitive adhesive.

18. The method of claim 12, wherein the adhesive comprises a removable pressure sensitive adhesive.

19. The method of claim 12, wherein the protective film is substantially transparent.

20. The method of claim 13, wherein the majority portion of the split release liner comprises at least two sections of release liner;

and

wherein removing the majority portion of the split release liner comprises removing the at least two sections of release liner; and

wherein adhering the second portion of the protective film to the surface may comprise successively adhering sections of the second portion of the protective film as each of the at least two sections of release liner are removed.

21. The method of claim 12, further comprising:

aligning the protective film with respect to the surface using a third tab extending from the protective film; and

removing the third tab from the protective film after the second portion of the protective film has been adhered to the surface.
