Description

Easy-to-remove protective film

The technology of the present invention relates to a protective film, especially a protective film that is easy to tear.

In order to prevent components such as display screens or outer frames of mobile phones, computers, TVs, etc. from being accidentally rubbed, touched, or scratched or contaminated by foreign objects during the manufacturing process, generally a protective film is attached to the parts to be protected for protection . After the protective film is attached to the flat surface, a vacuum state is present between the protective film and the flat surface. When the protected object enters the next production or use stage, the protective film needs to be torn off. When the protective film is torn off from the plane, it needs a large tearing force to overcome the vacuum adsorption, and it is difficult to find a tear around the protective film. The position of the force makes the protective film difficult to tear.

In order to facilitate the removal of the protective film, a handle is generally provided on one side edge of the protective film to facilitate the operator to pull the handle to remove the protective film from the protected object. In order to meet different special needs, there will also be a folding handle design to avoid interference with the assembly of the protective film on the line. However, the process of tearing off the protective film with the handle is to overcome the surrounding atmospheric pressure to separate the two. However, due to the close relationship between the two, it is difficult to separate the two (breaking the vacuum), and the product may be pulled and damaged.

The main object of the present invention is to provide a protective film that is easy to tear. To achieve the above purpose, the present invention is achieved by the following technical means. Among them, the present invention provides a protective film that is easy to tear, including a main body, a Hand and a broken vacuum. The main body is used for attaching to the surface of an object, so that a vacuum state exists between the main body and the surface of the object. The handle portion is disposed on the periphery of the main body, and is used for a user to hold the force required when the main body is torn off from the object.

In an embodiment of the invention, the handle portion further includes an extending body extending outward along the peripheral edge of the main body and at a distance from the surface of the object.

The technical means and structure adopted by the present invention are described in detail in terms of the embodiments of the present invention. The features and functions are as follows, but it should be noted that the content does not constitute a limitation of the present invention.

Please refer to FIG. 1 and FIG. 2 at the same time, which are a cross-sectional view and a top view of the structure of the first embodiment of the protective film of the present invention that is easy to tear. The invention provides a protective film that is easy to tear and is applied to an object that needs to be detached from the protective film. The protective film includes: a main body 1, a handle 2 and a vacuum break 3.

The main body 1 includes a first surface 11 and a second surface 12, the second surface 12 can be attached to the surface of an object 5 by electrostatic bonding, so that a vacuum state exists between the main body 1 and the surface of the object . In an embodiment of the present invention, the body 1 may be made of materials such as ethylene terephthalate, polyethylene plastic film, and polyvinyl chloride.

The handle portion 2 is provided on the periphery of the main body 1 for holding by the user to tear the main body 1 away from the object. It is worth mentioning that the handle portion 2 can be integrally formed with the body 1 or can be adhered to the body 1 through an adhesive member (not shown), wherein the adhesive member and the handle The adhesion strength between the parts 2 needs to be greater than the adsorption force between the body 1 and the surface of the object.

The vacuum break 3 is provided along the edge of the main body 1 and may be provided on both sides of the handle portion 2, but not limited to this, the vacuum break 3 may be evenly distributed on the main body 1. The design of the vacuum break 3 enables the vacuum to be broken with a small force during the drawing (tearing) process, effectively reducing the force required by the user to tear the main body 1 away from the object.

In an embodiment of the present invention, the vacuum break 3 includes a plurality of J-shaped vacuum break lines provided on both sides of the handle portion 2.

Please refer more to FIG. 3, which is a cross-sectional view of a structure of a second embodiment of a protective film that is easy to tear according to the present invention. The second embodiment of the present invention provides a protective film that is easy to tear, and includes a main body 1a, a handle portion 2a, and a vacuum break 3.

The main body 1a includes a first surface 11a and a second surface 12a. The second surface 12a can be attached to the surface of an object 5 by electrostatic bonding, so that a vacuum state exists between the main body 1a and the surface of the object .

The handle portion 2a is provided on the periphery of the main body 1a for holding by the user to detach the main body 1a from the object.

The vacuum break 3 is provided along the edge of the main body 1a, and it can be provided on both sides of the handle portion 2a, but not limited to this, the vacuum break 3 can be evenly distributed on the main body 1a. Wherein, the handle portion 2a further includes an extending body 21a that extends outward along the periphery of the main body 1a and is at a distance D from the surface of the object. The design of the extending body 21a makes it easier for the air to enter the vacuum breaking port 3 during the drawing (tearing) process to achieve the vacuum breaking, which more effectively reduces the force required when the user tears the main body 1a away from the object.

Please refer to FIG. 4 more, which is a schematic diagram 1 of the vacuum breakage of the protective film structure that is easy to tear according to the present invention. In an embodiment of the present invention, the vacuum breaking fracture 3a includes a plurality of line-type vacuum breaking lines disposed at the corners of the main body 1.

Please refer to FIG. 5 more, which is a second schematic diagram of the vacuum break of the protective film structure that is easy to tear according to the present invention. In an embodiment of the present invention, the vacuum breaking break 3b includes a plurality of L-shaped vacuum breaking lines provided on both sides of the handle portion 2.

Please refer to FIG. 6 more, which is a schematic diagram 3 of the vacuum breakage of the protective film structure which is easy to tear according to the present invention. In an embodiment of the invention, the vacuum breaking fracture 3c includes a plurality of cross-shaped vacuum breaking lines evenly distributed on the main body 2.

Please refer to FIG. 7 more, which is a schematic diagram 4 of the vacuum breakage of the protective film structure that is easy to tear according to the present invention. In an embodiment of the present invention, the vacuum breaking fracture 3d includes a plurality of arc-shaped vacuum breaking lines evenly distributed on the main body 2.

Therefore, please refer to all drawings, the present invention provides an easy-to-tear protective film, which can be applied to objects that need to be detached from the protective film, and the vacuum breaking is used to reduce the force required to break the vacuum, so that the tear off The protective film process can be completed with less effort to avoid product damage due to pulling.

The above are only examples of the present invention, and thus do not limit the implementation and protection scope of the present invention. Those skilled in the art should be able to realize that equivalent replacements and equivalents made by using the description and the illustrated content of the present invention The solutions obtained by the obvious changes should be included in the protection scope of the present invention.
