Description

Membrane assembly

The present invention relates to a film assembly, and more particularly to a film assembly that is easily attached to one of the surfaces of an article.

Many users currently attach a film to the surface in order to prevent the surface of an object from being scratched by foreign objects or to impart other properties to the surface. For example, users often attach protective films or optical films with special optical properties to the screens of various electronic products, or users often attach thermal insulation films, and anti-UV films are equivalent to windows or residential windows. In various bonding processes, it is often necessary to attach a hard substrate to the surface of the article, such as attaching a layer of glass to a panel.

Referring to FIG. 1, a conventional film assembly 1 generally comprises an application sheet 11 which is intended to be applied and attached to the surface 20 of the article 2, a release film 13 covering one of the inner surfaces of the application sheet 11, and a coating applied thereto. One of the outer surfaces of the sheet 11 is separated from the film 15.

In use, the user must first tear at least a portion of the edge 10 of the inner release film 13 adjacent the application sheet 11 from the inner surface of the application sheet 11 to expose a portion of the inner surface of the application sheet 11 to substantially approximate the edge 10. A portion of the inner surface of the application sheet 11 is attached to the surface 20 of the article 2 after the alignment of one of the articles 2 is predetermined. Thereafter, after all of the inner release film 13 is torn from the inner surface of the application sheet 11, the inner surface of the application sheet 11 is entirely attached to the surface 20 of the article 2. Finally, the attachment process of the application sheet 11 is completed after the outer release film 15 is torn from the outer surface of the application sheet 11.

However, in the case where the user does not use a special tool, it is often difficult to perfectly attach and align the application sheet 11 to the predetermined attachment position of the surface 20 of the article 2 at one time, and it is necessary to peel off the application sheet 11 and re-attach it multiple times. The predetermined attachment position of the application sheet 11 to the surface 20 of the article 2 is attached and aligned. This causes inconvenience to the general user when using the film assembly 1.

Moreover, the user generally does not attach the application sheet 11 to the surface 20 of the article 2 in a dust-free environment, so that dust is repeatedly applied during the process of repeatedly attaching and aligning the application sheet 11 to the predetermined attachment position of the surface 20 of the article 2. Or an undesired substance such as a stain on the user's hand is relatively easily adhered to the inner surface of the application sheet 11 attachable, and the undesired substance is adhered between the application sheet 11 and the surface 20 of the article 2, thereby causing application. The sheet 11 is not completely applied to the surface 20 of the article 2 and also affects the appearance of the article 2.

Another conventional membrane assembly 9 for attachment to the surface 20 of the object 2 is shown in Figure 2A. The conventional film assembly 9 comprises an application sheet 91, a juxtaposed first inner release film 92, a first adhesive layer 93 between the application sheet 91 and the first inner release film 92, and a first inner release type. A second adhesive layer 94 on the inner surface of the film 92 and a second inner release film 95 disposed on the inner surface of the second adhesive layer 94. When the conventional film assembly 9 is to be used, after the second inner release film 95 is first peeled off from the second adhesive layer 94, the second adhesive layer 94 of the conventional film assembly 9 is attached to the article 2. Surface 20 is shown in Figure 2B. Second, one of the first inner release film 92 is bent downward and torn from the middle as shown in Fig. 2C. Third, a portion of the first adhesive layer 93 exposed after the first inner release film 92 is peeled off is attached to the surface 20 of the article 2, as shown in FIG. 2D. Fourth, the other of the first inner release film 92 is bent and torn off as shown in Fig. 2E. Finally, the first adhesive layer 93 is all attached to the surface 20 of the article 2 such that the application sheet 91 is attached to the surface 20 of the article 2, as shown in Figure 2F.

The film assembly 9 can avoid repeated attaching and aligning the process of applying the first adhesive layer 93 on the sheet 91 to the predetermined attachment position of the surface 20 of the article 2, but peeling and tearing off the first inner release film from the middle. At 92 o'clock, undesired substances such as dust or stains on the user's hands are relatively easily adhered to the first adhesive layer 93 on the application sheet 91, and the undesired substance is adhered to the first adhesive layer on the application sheet 91. 93 is placed between the surface 20 of the article 2, causing the application sheet 91 not to be completely conformed to the surface 20 of the article 2. Furthermore, it is not easy to peel off the first inner release film 92 from the middle.
