Abstract
Description
Technical Field
[0001] This application relates to the field of protective film technology, and more specifically, to a tear-resistant sleeve protective film. Background Technology
[0002] In the field of electronic devices, especially for protecting mobile phone camera modules, sleeve-type protective films are widely used. These films effectively prevent physical damage to the camera from external sources, thus protecting its performance. However, when foam is typically used as the support material in the sleeve section, the foam is prone to delamination. This problem can lead to unstable product performance in practical applications, resulting in a poor user experience. Utility Model Content
[0003] The technical problem to be solved by the embodiments of this application is to prevent the sleeve from delaminating and cracking due to the tearing force of the top pulling upwards during the peeling process.
[0004] To address the aforementioned technical problems, this application provides a tear-resistant sleeve protection, employing the following technical solution:
[0005] From top to bottom, it includes a high-permeability membrane, a first double-sided adhesive, foam, a second double-sided adhesive, a polymer membrane, and a third double-sided adhesive.
[0006] The second double-sided adhesive is disposed at the bottom of the foam, the polymer film is disposed at the bottom of the second double-sided adhesive, the third double-sided adhesive is disposed at the bottom of the polymer film, and the high-permeability film is bonded to the top of the foam through the first double-sided adhesive.
[0007] The high-permeability membrane is provided with an upper tear handle, and a long handle is provided on the side wall of the polymer membrane. The long handle is bent upward and adhered and fixed to the upper tear handle.
[0008] Furthermore, the handle of the long strip is adhered to the side wall of the foam.
[0009] Furthermore, the upper tear handle is disposed on the side wall of the high-permeability film, and its orientation is the same as that of the long handle.
[0010] Furthermore, the long handle includes a first folded end close to the side wall of the foam, a first end of the first folded end being disposed on the side wall of the polymer film, a second end of the first folded end being disposed on a second folded end, and the second folded end being bonded to the upper tear handle.
[0011] Furthermore, a hollow area is provided at the center of the foam, the second double-sided adhesive, the polymer film, the third double-sided adhesive, and the first double-sided adhesive.
[0012] Furthermore, the high-permeability membrane is made of either polyester fiber or polyvinyl chloride.
[0013] Furthermore, the upper tear handle and the high-permeability film are made as a single integrated structure.
[0014] Furthermore, the polymer film is made of any one of PP, PE, and PET.
[0015] Furthermore, the second double-sided adhesive is the same size and shape as the third double-sided adhesive.
[0016] Furthermore, the polymer membrane and the long handle are both made as a single integrated structure.
[0017] Compared with the prior art, the embodiments of this application have the following main advantages:
[0018] By adding a polymer film between the second and third double-sided adhesive strips at the bottom of the sleeve protective film, and the polymer film having a long handle in the tear direction of the sleeve protective film, this long handle is finally bonded and fixed to the upper tear handle of the sleeve. When the sleeve protective film is torn off, the long handle of the polymer film and the upper tear handle work together to exert force, which is equivalent to applying force to the bottom of the foam, causing the sleeve to tear off from the bottom object. This greatly reduces the overall peeling force on the foam during the tearing action, thereby avoiding the problem of foam tearing and delamination. Attached Figure Description

[0027] This application provides a tear-resistant sleeve protective film.
[0028] High-permeability membrane 100, first double-sided adhesive 200, foam 300, second double-sided adhesive 400, polymer membrane 500 and third double-sided adhesive 600;
[0029] The second double-sided adhesive 400 is disposed at the bottom of the foam 300, the polymer film 500 is disposed at the bottom of the second double-sided adhesive 400, the third double-sided adhesive 600 is disposed at the bottom of the polymer film 500, and the high-permeability film 100 is bonded to the top of the foam 300 by the first double-sided adhesive 200.
[0030] The high-permeability membrane 100 is provided with an upper tear handle 700, and the polymer membrane 500 is provided with a long handle 800 on its side wall. The long handle 800 is bent upward and bonded to the upper tear handle 700.
[0031] By adding a polymer film 500 between the second double-sided adhesive 400 and the third double-sided adhesive 600 at the bottom of the sleeve protective film, the polymer film 500 has a long handle 800 in the tear direction of the sleeve protective film. This long handle is finally bonded and fixed to the upper tear handle 700 of the sleeve. When the sleeve protective film is torn off, the long handle 800 of the polymer film 500 and the upper tear handle 700 work together to exert force, which is equivalent to applying force to the bottom of the foam, causing the sleeve to tear off from the bottom object. This greatly reduces the peeling force on the foam during the tearing action, thereby avoiding the problem of foam tearing and delamination.
[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0033] Embodiment 1 of the tear-resistant sleeve protective film of this application
[0034] like Figure 1-3 As shown, the tear-resistant sleeve protective film of this application includes, from top to bottom, a high-permeability film 100, a first double-sided adhesive 200, foam 300, a second double-sided adhesive 400, a polymer film 500, and a third double-sided adhesive 600.
[0035] The second double-sided adhesive 400 is disposed at the bottom of the foam 300, the polymer film 500 is disposed at the bottom of the second double-sided adhesive 400, the third double-sided adhesive 600 is disposed at the bottom of the polymer film 500, and the high-permeability film 100 is bonded to the top of the foam 300 by the first double-sided adhesive 200.
[0036] The high-permeability membrane 100 is provided with an upper tear handle 700, and the polymer membrane 500 is provided with a long handle 800 on its side wall. The long handle 800 is bent upward and bonded to the upper tear handle 700.
[0037] Through the above structural design, a polymer film 500 is added between the second double-sided adhesive 400 and the third double-sided adhesive 600 at the bottom of the sleeve protective film. The polymer film 500 has a long handle 800 in the tear direction of the sleeve protective film. This long handle is finally bonded and fixed to the upper tear handle 700 of the sleeve. When the sleeve protective film is torn off, the long handle 800 of the polymer film 500 and the upper tear handle 700 exert force together, which is equivalent to applying force to the bottom of the foam, causing the sleeve to tear off from the bottom object. This greatly reduces the peeling force on the foam during the tearing action, thereby avoiding the problem of foam tearing and delamination.
[0038] like Figure 1-3 As shown, specifically, the handle of the long handle 800 is bonded to the side wall of the foam 300.
[0039] The above structural design further reduces the separation phenomenon of foam 300 during the peeling process.
[0040] like Figure 1-3 As shown, specifically, the upper tear handle 700 is disposed on the side wall of the high-permeability membrane 100, and its orientation is the same as that of the long handle 800.
[0041] Through the above structural design, the orientation of the upper tear handle 700 is the same as that of the long handle 800, which facilitates the adhesion of the upper tear handle 700 and the long handle 800 to each other and helps to prevent the foam 300 from separating when it is necessary to peel off the foam 300.
[0042] like Figure 1-3 As shown, specifically, the long handle 800 includes a first folded end 810 close to the side wall of the foam 300. The first end of the first folded end 810 is disposed on the side wall of the polymer film 500, and the second end of the first folded end 810 is disposed on a second folded end 820. The second folded end 820 is bonded to the upper tear handle 700.
[0043] Through the above structural design, the first folded end 810 further reduces the separation phenomenon of foam 300 during the peeling process, and the second folded section is bonded to the upper tear handle 700, which is conducive to transferring the overall peeling force to the polymer film 500 through the long handle 800.
[0044] like Figure 1-3 As shown, specifically, the foam 300, the second double-sided adhesive 400, the polymer film 500, the third double-sided adhesive 600, and the first double-sided adhesive 200 all have hollowed-out areas in their central positions.
[0045] Through the above structural design, the hollow area is applied to the mobile phone camera module.

[0048] Through the above structural design, the high-permeability membrane 100 is made of polyester fiber in this design.
[0049] Embodiment 3 of the anti-tear sleeve protective film of this application
[0050] like Figure 1-3As shown, specifically, the upper tear handle 700 and the high-permeability film 100 are made into an integrated structure.
[0051] Through the above structural design, the upper tear handle 700 and the high-permeability film 100 are made into an integrated structure, which is beneficial to the integrity and increases the strength of the internal structure.
[0052] like Figure 1-3 As shown, specifically, the polymer film 500 is made of any one of PP, PE and PET.
[0053] Based on the above structural design, the polymer film 500 in this design is made of PET.
[0054] like Figure 1-3 As shown, specifically, the second double-sided adhesive 400 and the third double-sided adhesive 600 are the same size and shape.
[0055] Through the above structural design, the second double-sided adhesive 400 and the third double-sided adhesive 600 are the same size and shape, preventing structural interference caused by their different structures.
[0056] like Figure 1-3 As shown, specifically, the polymer membrane 500 and the long handle 800 are both made as a single piece.
[0057] Through the above structural design, the polymer membrane 500 and the long handle 800 are made into an integrated structure, which is beneficial to the integrity and increases the strength of the internal structure.
