[0026] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0027] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, top, bottom, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0028] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] Reference below Figures 1-4 The easy-tear marking tape according to the embodiment of the present invention is described.

[0031] like Figures 1-4As shown, the easy-to-tear labeling tape includes a tape 100 wound into a roll. The tape 100 includes a release film layer 210, a labeling layer 220, a substrate layer 230, and an adhesive layer 240 connected in sequence. The release film layer 210, the labeling layer 220, the substrate layer 230, and the adhesive layer 240 are sequentially bonded to form the tape 100.

[0032] Specifically, a tear rack 110 is provided on either side of the tape 100, and the tooth width of the tear rack 110 is 1 mm to 1.5 mm. The user can tear the tape 100 horizontally from the middle of the tear rack 110 on one side to cut the tape 100. This allows the tape 100 to be torn without cutting tools, making it more convenient to use. The tooth width of the tear rack 110 should not be too large or too narrow. A too wide tooth width can easily affect the structural strength of the tape 100, and during the pasting process, the tape 100 can easily be pulled and cracked at the tear rack 110. A too narrow tooth width can easily affect the operability of cutting the tape 100 after pasting.

[0033] The labeling layer 220 is provided with evenly spaced labeling strips 221, which are arranged at an angle along the extension direction of the labeling layer 220. When the user is looking for the tape end of the adhesive tape 100, they only need to locate the end of the labeling strip 221 to locate the tape end of the adhesive tape 100. When using the easy-to-tear labeling tape of the present invention, the user only needs to locate the labeling strip 221 on the surface of the film that is inconsistent with the other lengths, and then find the end of the labeling strip 221 along its extension direction. The corresponding end of the labeling strip 221 is the location of the tape end of the adhesive tape.

[0034] Conventional transparent film typically relies on marking the tape tip with a bend mark or finding a stair-stepped section along the film surface to locate the tape tip. However, sometimes users forget to mark the tape tip in advance, or the film surface becomes uneven due to environmental factors, making it more difficult for users to locate the tape tip.

[0035] The easy-to-tear marking tape of the present invention does not require locating the tape head by feel or pre-marking. The tape head of the film can be found by quickly searching for the marking strips 221 of different lengths on the surface of the film.

[0036] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the width of the identification strip 221 is 1 mm to 2 mm and is arranged obliquely along the extension direction of the tape 100. The width of the identification strip 221 is set within a specified range to avoid the identification strip 221 being too thick and affecting the user's judgment of its length, or too thin and making it difficult for the user to visually observe the position of the identification strip 221.

[0037] Furthermore, if Figure 3 and Figure 4As shown, adjacent identification strips 221 are arranged in parallel. In order to avoid visual interference between the identification strips 221, adjacent identification strips 221 are arranged in parallel, thereby improving the user's judgment accuracy on the length of the identification strips 221.

[0038] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, a positioning vertical line 222 is provided at the intersection of the end of the identification strip 221 and the side of the adhesive tape 100 , and the positioning vertical lines 222 of the head and tail of adjacent identification strips 221 overlap.

[0039] Specifically, the positioning vertical line 222 is perpendicular to the intersection of the end of the identification strip 221 and the side of the tape 100. The positioning vertical line 222 is perpendicular to the side of the tape 100. In this embodiment, the positioning vertical lines 222 at the head and tail of adjacent identification strips 221 overlap, ensuring that only one identification strip 221 is cut each time the tape 100 is cut. The user only needs to locate a group of identification strips 221 to quickly find the tape head.

[0040] In some embodiments of the present invention, the light transmittance of the substrate layer 230 is lower than that of the release film layer 210. The release film layer 210 is made of a transparent material, allowing the user to observe the identification stripe 221 of the identification layer 220 through the release film layer 210. When the adhesive tape 100 is rolled, only the identification stripe 221 of the topmost layer of the adhesive tape 100 is visible. Specifically, the substrate layer 230 is made of a dark material with low light transmittance to prevent the identification stripe 221 below the surface of the adhesive tape 100 from being visible through the substrate layer 230 when the adhesive tape 100 is wound into a roll, causing visual interference and hindering the user's ability to observe the location of the identification stripe 221 on the surface of the tape roll.

[0041] In some embodiments of the present invention, the marking strip 221 is provided with a fluorescent coating. In order to improve the marking effect of the marking strip 221, the marking strip 221 can also be coated with a fluorescent coating to enhance its marking effect, making it easier for users to use the film in a dimly lit environment.

[0042] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, tearing racks 110 are respectively provided on both sides of the adhesive tape 100. Specifically, tearing racks 110 are respectively provided on both sides of the adhesive tape 100 in this embodiment, and the user can cut the adhesive tape 100 from any side.

[0043] Furthermore, in order to prevent accidental scratches caused by the tooth tips of the tear rack 110 , the tooth tips of the tear rack 110 in this embodiment are provided with arc shapes.

[0044] In some embodiments of the present invention, the width of the tape 100 is 30 mm to 60 mm. Specifically, the specifications of the easy-tear marking tape of the present invention are between 30 mm and 60 mm. The thickness of the tape 100 generally increases with the width. Tapes 100 with a width greater than 60 mm are thicker, allowing users to quickly locate the tape head by feel alone, eliminating the need for the marking strip 221 structure of the present embodiment. However, for tapes 100 with a width less than 30 mm, the marking strip 221 is too short and difficult to detect, making the marking strip 221 structure of the present embodiment less meaningful.

[0045] In actual use, the user uses the two sides of the tape 100 as the boundary. As long as both ends of the identification strip 221 intersect with the two sides of the tape 100, the length of the identification strip 221 does not need to be considered. The user only needs to quickly locate the end of the identification strip 221 between the two sides of the tape 100. The end of the identification strip 221 is the tape end of the tape 100.

[0046] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the illustrative use of the above terms does not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
