technical field

The utility model relates to the technical field of protective film, more specifically, it relates to an integrated hand tearing protective film.

Background technique

In order to prevent LCD screens and mobile phone screens from accidentally being scratched or foreign objects caused by factors such as friction and touch during the production process, a protective film is required to protect the LCD screen and mobile phone screen during the production process. Since the protective film is a process material, it needs to be torn off when it flows into the next link. Since the protective film is sticky, it is directly attached to the screen. When peeling off the protective film, it is necessary to look for possible where it is torn so that it can be peeled off. In order to facilitate the peeling of the protective film, an easy-to-tear protective film has appeared on the market. The corner of the easy-to-tear protective film has a tearing hand that protrudes outwards and is convenient for lying down. The protective film can be easily peeled off by pinching the lying holding end of the tearing hand with your hands and pulling it hard.

However, the existing easy-to-tear protective film generally adopts bonding to prevent fixed tearing, and the connection stability between the tearing hand and the main body of the protective film is not very high. This kind of easy-to-tear protective film has weak tear resistance at the tearing point, and often because the protective film is attached for too long, the tearing hand will fall off when the tearing hand is pulled and the protective film cannot be peeled off. When this happens, it often leads to increased rework times, and the production efficiency and yield of the product are adversely affected.

Embodiment one:

Referring to FIG. 1 , an integrated protective film for tearing hands 2 . It includes the main body of the protective film 1 and the tearing handle 2. The tearing handle 2 is located at the edge of the protective film. The tearing handle 2 and the protective film are integrally punched and formed from the same material. The lying end of the tearing handle 2 faces the outside of the protective film main body 1 stick out. The tearing hand 2 is provided with a bonding area, the bonding area has a certain distance from the junction of the protective film main body 1 and the tearing hand 2, and the bonding area also has a certain distance from the lying end of the tearing hand 2. In this embodiment, the bonding area is the double-sided adhesive tape 3 pasted on the surface of the tearing handle 2, and what the double-sided adhesive tape 3 adopts here is 3M double-sided adhesive tape.
