[0002] With technological advancements, various electronic devices are becoming increasingly popular. Their surfaces are susceptible to damage such as scratches and stains, which can affect the product's appearance and lifespan. Consequently, the demand for protective films has arisen. In the early days, single-layer protective films were the mainstream, but their effectiveness was limited. To improve protection and reduce supply chain costs, double-layer protective film technology has gradually emerged.

[0003] Existing double-layer protective film such as Figure 1 , both achieve film removal by adding an easy-tear sticker or other attachments to the double-layer protective film. The step difference between the easy-tear sticker and the protective film can create bubbles between the two layers of protective film, which can easily leave film marks on the surface of electronic devices when attached, failing to provide complete protection and even increasing the risk of poor appearance.

[0006] The technical solutions that further define the utility model include:

[0007] The bottom of the bottom protective film tear handle is not provided with a glue layer.

[0008] The top surface of the bottom protective film is a release layer.

[0009] The top protective film tearing handle and the bottom protective film tearing handle have no sharp corners.

[0010] The top protective film tearing handle and the bottom protective film tearing handle are polygonal or arc-shaped.

[0011] The bottom protective film and the top protective film are both PET films.

[0012] Through the above technical scheme, the beneficial effects of the utility model are as follows: the side edge of the top protective film of the optical film of the double-layer protective film of the utility model is provided with a top protective film tearing hand, the top protective film tearing hand and the top protective film are integrated, there is no adhesive layer at the bottom of the top protective film tearing hand, and an anti-fool silk screen is provided on the top of the top protective film tearing hand, and the side edge of the bottom protective film is provided with a bottom protective film tearing hand, and the bottom protective film tearing hand is integrated with the bottom protective film. The two layers of film materials are stacked together and cut into one film. During use, if the top layer of film material is damaged or dirty, the top protective film can be conveniently torn off through the top protective film tearing hand, and the bottom protective film can still be used. There is no adhesive layer at the bottom of the top protective film tearing hand, which is convenient for tearing off the top protective film and the top protective film tearing hand will not be stained with the bottom protective film tearing hand. The top protective film tearing hand is provided with an anti-fool silk screen to prevent the film material from being pasted incorrectly, and it is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The structure of the present invention is further described below with reference to the accompanying drawings.

[0018] Reference Figures 1 to 4The double-layer protective film of the present invention includes a bottom protective film 1, a bottom protective film adhesive layer 2, a top protective film 3, and a top protective film adhesive layer 4. The top protective film adhesive layer is located at the bottom of the top protective film, and the bottom protective film adhesive layer is located at the bottom of the bottom protective film. Both the bottom protective film and the top protective film are PET films. A top protective film tearing handle 31 is provided on the side edge of the top protective film. The top protective film tearing handle is integrally arranged with the top protective film. There is no adhesive layer at the bottom of the top protective film tearing handle. An anti-fool silk screen 32 is provided on the top of the top protective film tearing handle 31. A bottom protective film tearing handle 11 is provided on the side edge of the bottom protective film 1. The bottom protective film tearing handle is integrally arranged with the bottom protective film. The top protective film tearing handle is located above the bottom protective film tearing handle and covers the bottom protective film tearing handle. In this embodiment, the top protective film tearing handle and the bottom protective film tearing handle are rectangular. In specific implementation, the top protective film tearing handle and the bottom protective film tearing handle can be set to polygonal or arc-shaped. The top protective film tearing handle and the bottom protective film tearing handle have no sharp corners. When the top protective film tearing handle and the bottom protective film tearing handle are polygonal, the sharp corners need to be rounded to prevent the sharp corners from cutting the hands. In specific implementation, rounded corners can also be omitted. The top protective film tearing handle is integrally provided with the top protective film, and the bottom protective film tearing handle is integrally provided with the bottom protective film. The two layers of film are stacked together and cut to form a film. During use, if the top layer of film is damaged or dirty, the top protective film can be easily torn off with the top protective film tearing handle, and the bottom protective film can still be used. There is no adhesive layer at the bottom of the top protective film tearing handle, which facilitates the tearing off of the top protective film and prevents the top protective film tearing handle from getting stained by the bottom protective film tearing handle. There is an anti-foolproof silk screen on the top of the top protective film tearing handle to prevent the film from being pasted incorrectly, making it easy to use. In this embodiment, there is no adhesive layer at the bottom of the bottom protective film tearing handle. This makes it easy to tear off the bottom protective film when it is damaged. In specific implementation, the bottom protective film tearing handle can also be provided with an adhesive layer. The top surface of the bottom protective film is a release layer. The release layer facilitates the separation of the bottom protective film from the adhesive layer of the top protective film, making it easy to tear off the top protective film.

[0019] Although the specific embodiments of the present invention are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of the present invention. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of the present invention.
