Description

Protective film

The present invention relates to a protective film, particularly a protective film having a tear-off member.

In order to prevent the surface of the product from being scratched, it is necessary to provide a protective film on the surface for protection before using the product. However, the protective film in the prior art, such as the protective film on the touch sensing film, is usually the same size as the surface of the product to be protected. When the operator separates the protective film from the touch sensing film, it is often necessary to use the fingertip to move the air between the protective film and the touch sensing film at the edge or corner, so that the air enters the air between the two. Gradually separate the two, this operation is very inefficient and wastes working hours.

In view of this, it is necessary to provide a protective film that is easily peeled off.

A protective film for protecting a surface of a protective object, the protective film comprising a body having oppositely disposed first surfaces and second surfaces, the first surface being attached to the object to be protected, the body The edge is provided with a notch, the notch exposing a portion of the object to be protected, the protective film further comprising a tearing portion disposed on the second surface of the body, the tearing portion being disposed adjacent to the notch and attached to the first portion by means of a gel The two surfaces, the adhesive force of the tearing portion and the main body is greater than the adhesion force of the main body and the object to be protected.

Compared with the prior art, the protective film is provided with a tearing portion, and when the protective film is peeled off from the object to be protected by the tearing portion, the operation is convenient, especially in the case of the gap, the tearing effect is better. .

2 is a schematic perspective view of a second embodiment of the protective film of the present invention.

Fig. 3 is a perspective view showing a third embodiment of the protective film of the present invention.

Referring to FIG. 1, the protective film 2 is attached to the surface of the object to be protected to provide protection for the object to be protected. In the embodiment, the object to be protected is the touch sensing film 1 . It can be understood that the object to be protected may also be a light guide plate, a liquid crystal panel, a polarizer or the like. In the embodiment, the touch sensing film 1 is a rectangular thin plate or a rectangular sheet structure, and includes a to-be-protected area 11 . In the embodiment, the to-be-protected area 11 is the upper surface of the touch sensing film 1 . . The shape of the main body 21 of the protective film 2 is substantially the same as the shape of the touch sensing film 1, or the shape of the main body 21 of the protective film 2 is substantially the same as the shape of the area 11 to be protected of the touch sensing film 1. Thin plate or rectangular sheet structure.

The protective film 2 includes the main body 21 and a tearing portion 27 provided on the main body 21. The tear-off portion 27 is provided on the surface of the main body 21. Specifically, the body 21 has a first surface 22 and a second surface 23 that are oppositely disposed. The first surface 22 is used to attach the to-be-protected area 11 of the touch sensing film 1 . The tear-off portion 27 is fixed to the second surface 23 by means of a glue 26. The adhesive force of the tearing portion 27 and the main body 21 is greater than the adhesion force of the main body 21 and the touch sensing film 1 . In the present embodiment, the area of the tear-off portion 27 is smaller than the area of the main body 21. In the direction in which the tear-off portion 27 and the main body 21 are stacked, the edge of the tear-off portion 27 does not protrude from the edge of the main body 21. In the present embodiment, the edge of the tear-off portion 27 away from the center of the protective film 2, the edge of the colloid 26 away from the center of the protective film 2, and the side edge of the main body 21 overlap.

The edge of the body 21 has a notch 25. Preferably, the notch 25 is disposed on the main body 21 Corner. The tear-off portion 27 is disposed adjacent to the notch 25. The colloid 26 is also disposed adjacent to the gap 25. The area of the tear-off portion 27 is larger than the area of the colloid 26, and the portion of the tear-off portion 27 where the colloid 26 is not disposed is closer to the center of the protective film 2 than the portion where the colloid 26 is disposed, in the tear-off portion. A gap 29 is formed between the body 27 and the body 21.

When the protective film 2 is attached to the touch sensing film 1 , the notch 25 exposes an edge portion of the touch sensing film 1 to be protected. When the protective film 2 is peeled off the touch sensing film 1, first, the end of the tearing portion 27 where the colloid 26 is not provided is gradually enlarged by the external force and the gap 29 between the main body 21, so that the tearing is performed. The colloid 26 of the separation portion 27 drives the colloid 26 and the main body 21 to move away from the touch sensing film 1; the notch 25 is disposed so that the edge of the main body 21 forming the notch 25 is first and the touch sensing film 1 The detachment gradually drives the main body 21 completely separated from the touch sensing film 1.

Due to the arrangement of the tear-off portion 27, the protective film 2 is easily peeled off from the object to be protected, and the operation is convenient. Especially in the cooperation of the notch 25, the tearing effect is better. Further, the formation of the gap 29 facilitates the operator to tear the protective film 2 by holding the tear-off portion 27 via the gap 29. Further, since one side edge of the tear-off portion 27 overlaps with one side edge of the main body 21. Therefore, when the product adhered to the object to be protected by the protective film 2 is transported, the tear-off portion 27 is less affected by the friction and slight tear of the edge and is separated from the object to be protected, thereby losing the protection of the object to be protected.

Referring to FIG. 2, the second embodiment of the present invention is substantially the same as the first embodiment except that the tear-off portion 37 of the protective film 3 is a transparent material. A colored film 38 is provided on the tear-off portion 37. The color of the colored film 38 is different from the color of the main body 31. The body 31 can also be a transparent material. The arrangement of the colored film 38 allows the operator to quickly find the position of the tear-off portion 37, improving the operational efficiency. In the present embodiment, the colored film 38 is a mylar film, that is, a polyester film. The tear-off portion 37 is a polyethylene film (PE film) . The area of the colored film 38 and the colloid 36 is the same as the area of the tear-off portion 37. Specifically, the colored film 38 is disposed between the tear-off portion 37 and the main body 31, and is closer to the center of the protective film 3 than the colloid 36.

Referring to FIG. 3, the third embodiment of the present invention is substantially the same as the second embodiment, except that the tearing portion 47 of the protective film 4 has a first end portion 471 and a second end portion 472 disposed opposite to each other. The edge of the first end portion 471, the colloid 46, and the edge of the body 41 overlap. The body 41 covers the colored film 48. The colloid 46 is disposed in parallel with the colored film 48 between the tear-off portion 47 and the main body 41. The edge of the tear-off portion 47 having the second end portion 472 is longer than the edge of the colored film 48 to form a gap 49 with the body 41.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art will be included in the following claims.
