[0014] Preferably, two second backing papers are glued to the lower surface of the adhesive tape, and the second backing papers are located between the adhesive tape and the LDPE film.
[0015] The effects achieved by the above components are: the provision of the second backing paper reduces the adhesion area between the adhesive tape and the LDPE film, and also reduces the difficulty of tearing the adhesive tape from the LDPE film.
[0016] Preferably, two extension strips are fixedly connected to the side wall of the adhesive tape.
[0017] The effect achieved by the above components is that the extension strip is also provided to facilitate the work of tearing the tape from the LDPE film.
[0018] In summary:
[0019] In the utility model, the tearing notch is arranged on the adhesive tape instead of on the LDPE film. Firstly, the tearing notch and tearing seam can be avoided from being arranged on the LDPE film, which can easily reduce the tearing seam on the surface of the LDPE film during the use of the LDPE film, and can easily reduce the sealing effect of the use of the LDPE film. Secondly, the adhesive tape can effectively improve the use strength of the edge of the LDPE film, avoid the deformation of the edge of the LDPE film, and facilitate the tearing of the LDPE film. By setting the above structure, the adhesive tape is arranged on the edge of the LDPE film, and the tearing notch, tearing seam and other structures are added. While facilitating the smooth tearing of the LDPE film, the use strength of the edge of the LDPE film is improved, and the efficiency of taking the LDPE film is improved to a certain extent.

[0026] Reference Figure 1-5 As shown, the utility model provides a technical solution: an easy-tear LDPE film, including an LDPE film 1.
[0027] The following is a detailed description of its overall specific settings and functions.
[0028] In this embodiment: a plurality of adhesive tapes 2 are evenly bonded to the upper surface of the LDPE film 1, and a tearing notch 7 is provided on the side wall of the adhesive tape 2. The tearing notch 7 is provided on the adhesive tape 2 instead of on the LDPE film 1 because, firstly, the tearing notch 7 and the tearing seam 3 can be avoided from being provided on the LDPE film 1, which can easily reduce the tearing seam 3 on the surface of the LDPE film 1 during the use of the LDPE film 1, and can easily reduce the sealing effect of the use of the LDPE film 1; secondly, the adhesive tape 2 can effectively improve the use strength of the side of the LDPE film 1, avoid the side of the LDPE film 1 from being easily deformed, and facilitate the tearing of the LDPE film 1.
[0029] The surface of the adhesive tape 2 is evenly provided with a plurality of tearing seams 3, and the tearing seams 3 and the tearing opening 7 are on the same straight line. The LDPE film 1 is torn along a line arranged along the tearing seams 3, thereby facilitating the rapid tearing of the LDPE film 1. Two indentations 6 are provided on the upper surface of the adhesive tape 2, and cotton threads 8 are glued to the inner side of the indentations 6. By providing the cotton threads 8 on the inner side of the indentations 6, the tearing speed of the LDPE film 1 is avoided too fast, and the LDPE film 1 is easily torn crooked, and the tearing effect of the LDPE film 1 is further improved. By providing the LDPE film 1 in the indentations 6, the protrusion degree of the cotton threads 8 on the surface of the adhesive tape 2 can be reduced.
[0030] Specifically, two first backing papers 4 are glued to the lower side of the adhesive tape 2, and the first backing papers 4 are located between the adhesive tape 2 and the LDPE film 1. The first backing paper 4 is provided to facilitate the work difficulty of the staff when the adhesive tape 2 needs to be removed from the LDPE film 1 later. When the adhesive tape 2 is torn off from the LDPE film 1, it is convenient to tear the adhesive tape 2 from the other end of the LDPE film 1, which facilitates the work of taking a small piece of LDPE film 1.
[0031] Two second backing papers 9 are glued to the lower surface of the adhesive tape 2, and the second backing papers 9 are located between the adhesive tape 2 and the LDPE film 1. The provision of the second backing paper 9 reduces the adhesion area between the adhesive tape 2 and the LDPE film 1, and also reduces the difficulty of tearing the adhesive tape 2 from the LDPE film 1. Two extension strips 5 are fixedly connected to the side wall of the adhesive tape 2. The provision of the extension strips 5 is also to facilitate the work of tearing the adhesive tape 2 from the LDPE film 1.
[0032] Working principle: when the LDPE film 1 needs to be torn off, the staff can use the position of the tearing opening 7 to tear the LDPE film 1 along a line where the tearing seams 3 are arranged, thereby facilitating the rapid tearing of the LDPE film 1. The reason for setting the tearing opening 7 on the adhesive tape 2 instead of on the LDPE film 1 is that, firstly, it can avoid that the tearing opening 7 and the tearing seams 3 are set on the LDPE film 1, which can easily reduce the tearing seams 3 on the surface of the LDPE film 1 during the use of the LDPE film 1, and can easily reduce the sealing effect of the LDPE film 1. Secondly, the adhesive tape 2 can effectively improve the use strength of the side of the LDPE film 1, avoid the deformation of the side of the LDPE film 1, and facilitate the tearing of the LDPE film 1. By setting the cotton thread 8 on the inner side of the indentation 6, it can be avoided that the speed of tearing the LDPE film 1 is too fast, and the LDPE film 1 is easily torn crooked, thereby further improving the tearing effect of the LDPE film 1. The DPE film 1 is arranged in the indentation 6, which can reduce the protrusion of the cotton thread 8 on the surface of the tape 2. The first base paper 4 is arranged to facilitate the work difficulty of the staff when they need to remove the tape 2 from the LDPE film 1 later. The tape 2 can be torn off from the LDPE film 1, which can facilitate the tearing work from the other end side of the LDPE film 1, and it is convenient to take a small piece of LDPE film 1. The arrangement of the second base paper 9 reduces the adhesion area between the tape 2 and the LDPE film 1, and also reduces the difficulty of tearing the tape 2 from the LDPE film 1. The extension strip 5 is also arranged to facilitate the work of tearing the tape 2 from the LDPE film 1. By setting the above structure, the tape 2 is arranged on the side of the LDPE film 1, and the tearing notch 7, the tearing seam 3 and other structures are added. While facilitating the smooth tearing of the LDPE film 1, the use strength of the side position of the LDPE film 1 is improved, and the efficiency of taking the LDPE film 1 is improved to a certain extent.
