Description

protective film

technical field

The present invention relates to a protective film, especially a protective film with an easily tearable part.

Background technique

In order to prevent the surface of the product from being scratched, it is necessary to set a protective film on the surface of the product for protection before using it. 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 fingertips to move the two at the edge or corner where the protective film and the touch sensing film are bonded to allow air to enter between the two, and then Gradually make the two separate, such operation efficiency is very low and wastes man-hours.

Contents of the invention

In view of this, it is necessary to provide an easily tearable protective film.

A protective film, which is used to protect the surface of an object to be protected, the protective film includes a main body, the main body has a first surface and a second surface oppositely arranged, the first surface is attached to the object to be protected, the There is a notch on the edge of the main body, and the notch exposes part of the object to be protected. The protective film also includes a tear-off part arranged on the second surface of the main body. The tear-off part is adjacent to the notch and attached to the On the second surface, the bonding force between the peeling part and the main body is greater than the adhesion force between the main body and the object to be protected.

Compared with the prior art, the protective film is provided with a tear-off part, and the operation is more convenient when the protective film is torn off from the object to be protected through the tear-off part, especially with the cooperation of the gap, the tear-off effect is better .

Detailed ways

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 this embodiment, the object to be protected is the touch sensing film 1 . Understandably, the object to be protected may also be products such as light guide plates, liquid crystal panels, and polarizers. In this embodiment, the touch sensing film 1 is a rectangular thin plate or a rectangular sheet structure, which includes a region to be protected 11, and in this embodiment, the region to be protected 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, which is a rectangle. Thin plate or rectangular sheet structure.

The protective film 2 includes a main body 21 and a tear-off portion 27 disposed on the main body 21 . The tear-off portion 27 is disposed on the surface of the main body 21 . Specifically, the main body 21 has a first surface 22 and a second surface 23 opposite to each other. The first surface 22 is used for attaching the area 11 to be protected of the touch sensing film 1 . The tear-off portion 27 is fixed on the second surface 23 by glue 26 . The adhesive force between the peeling portion 27 and the main body 21 is greater than the adhesion force between the main body 21 and the touch sensing film 1 . In this embodiment, the area of the tear-off portion 27 is smaller than that of the main body 21 . In the lamination direction of the tear-off portion 27 and the main body 21 , the edge of the tear-off portion 27 does not protrude beyond the edge of the main body 21 . In this embodiment, the edge of the peeling portion 27 away from the center of the protective film 2 , the edge of the glue 26 away from the center of the protective film 2 , and the edge of the main body 21 overlap.

The edge of the main body 21 has a notch 25 . Preferably, the notch 25 is disposed at a corner of the main body 21 . The tear-off portion 27 is adjacent to the notch 25 . The glue 26 is also disposed adjacent to the notch 25 . The area of the tear-off part 27 is greater than the area of the glue 26, and the part of the tear-off part 27 that is not provided with the glue 26 is closer to the center of the protective film 2 than the part where the glue 26 is set, so that the tear-off part A gap 29 is formed between 27 and the main body 21 .

When the protective film 2 is pasted on the touch sensing film 1 , the notch 25 exposes the edge portion of the area 11 to be protected of the touch sensing film 1 . When the protective film 2 is torn off from the touch sensing film 1, firstly, the gap 29 between the end of the tear-off part 27 that is not provided with the colloid 26 and the main body 21 gradually becomes larger under the action of external force, so that the tear One end of the set colloid 26 on the part 27 drives the colloid 26 and the main body 21 to move away from the touch sensing film 1; detachment, and then gradually drive the main body 21 to completely separate from the touch sensing film 1 .

Due to the setting of the tear-off part 27, it is convenient to tear the protective film 2 from the object to be protected, and the operation is more convenient. Especially with the cooperation of the notch 25, the tearing effect is better. In addition, the formation of the gap 29 facilitates the operator to tear off the protective film 2 by holding the tear-off portion 27 through the gap 29 . Further, because one side edge of the tear-off portion 27 overlaps with one side edge of the main body 21 . Therefore, when the product after the protective film 2 is attached to the object to be protected is transported, the tear-off portion 27 is less affected by the friction and slight tearing of the edge to separate from the object to be protected, thereby losing the protection of the object to be protected.

Please refer to FIG. 2 , the second embodiment of the present invention is basically the same as the first embodiment, except that the tear-off portion 37 of the protective film 3 is made of transparent material. A colored film 38 is disposed on the tear-off portion 37 . The color of the colored film 38 is different from that of the main body 31 . The main 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 operating efficiency. In this embodiment, the colored film 38 is a mylar film (mylar), 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 glue 36 is the same as the area of the peeling part 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 glue 36 .

Please refer to FIG. 3 , the third embodiment of the present invention is basically the same as the second embodiment, the difference is that: the tear-off portion 47 of the protective film 4 has a first end 471 and a second end 472 oppositely arranged, Edges of the first end portion 471 , the glue 46 and the main body 41 overlap. The main body 41 is covered with a colored film 48 . The glue 46 and the colored film 48 are juxtaposed 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 main body 41 .
