In this embodiment, the extended end of the first bent portion 30 is located on a side of the release body 26 away from the protective layer 14, the pull connection portion 24 is located at the connection between the corresponding release connection portion 28 and the release body 26, and the end of the hard portion 22 close to the pull connection portion 24 is spaced a certain distance from the corresponding end of the soft portion 20. It should be understood that in other embodiments, the hard portion 22 may also be connected to the side of the soft portion 20 close to the release layer 16 .

[0033] In such Figure 4 In the embodiment shown, the structure of the protective film 10 is arranged similar to Figure 1-3 The embodiments shown are basically the same, except that: in this embodiment, the soft part 20 is connected to the side of the first bending part 30 close to the release body 26 through the pulling connection part 24, the soft part 20 and the pulling connection part 24 are both located on the side of the first bending part 30 close to the release body 26, and the hard part 22 is connected to the side of the soft part 20 close to the release layer 16. It should be understood that in other embodiments, the hard part 22 can also be connected to the side of the soft part 20 away from the release layer 16.

[0034] In such Figure 5 and Figure 6In the illustrated embodiment, the soft portion 20 includes a soft body 32 and a soft connection portion 34 extending outward from the soft body 32, the soft connection portion 34 is located on the circumferential outer side of the protective layer 14, the soft body 32 and the release body 26 are substantially the same in length, for example, the two are arranged to overlap each other, the protruding direction of the soft connection portion 34 is the same as the protruding direction of the release connection portion 28, the hard portion 22 is connected to the soft body 32, and the pulling connection portion 24 is connected to the soft connection portion 34. Further, the soft connection portion 34 includes a second bending portion 36 bent toward a side close to the protective layer 14, so that the soft connection portion 34 is U-shaped as a whole, and the pulling connection portion 24 is connected to a side of the second bending portion 36 away from the protective layer 14, for example, one side of the pulling connection portion 24 is connected to the end of the second bending portion 36, and the other side is connected to the end of the release connection portion 28. In this embodiment, the hard part 22 is connected to the side of the soft body 32 away from the protective layer 14, and there is a spacing distance between the end of the hard part 22 close to the pulling connection part 24 and the side corresponding to the protective layer 14. In other embodiments, the hard part 22 can also be connected to the side of the soft body 22 close to the protective layer 14.
