Abstract

A film assembly comprises an application sheet, and an inner release film comprises a first film portion, a second film portion and a pull portion. The first film portion covers an inner surface of the application sheet and is easily detachable. The second film portion forms one piece with the first film portion at a connection edge and folded thereunder. The pull portion is formed at the second film portion and protrudes out from a first edge of the first film portion. The pull portion is pulled along a pull direction away from the connection edge while the second film portion contacts the surface of the article to pull the second film portion in tandem, causing the first film portion to detach from the inner surface of the application sheet, such that the inner surface is attached to the surface of the article without attracting undesired substances.

Claims26

Dependent claims

A film assembly for attachment to a surface of an article, comprising:

an application sheet having an outer surface and an inner surface, wherein said inner surface of said application sheet is to be attached to said surface of said article;
and
an inner release film, wherein said inner release film comprises:
a first film portion covering said inner surface of said application sheet to prevent said inner surface of said application sheet from attracting undesired substances while being easy to detach from said inner surface of said application sheet, wherein said first film portion has a first edge;
and
a second film portion connected to and forming one piece with said first film portion at a connection edge and folded under said first film portion;
a pull portion formed at said second film portion and protruding out from said first edge of said first film portion, wherein said pull portion is pulled along a pull direction away from said connection edge while said second film portion contacts said surface of said article to pull said second film portion in tandem, causing said first film portion to detach from said inner surface of said application sheet, such that said inner surface of said application sheet is attached to said surface of said article without attaching said undesired substance.
