Description

Technical Field

[0001] This application relates to the field of adhesive tape technology, specifically a box sealing tape. Background Technology

[0002] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0003] Packaging tape, also known as BOPP tape or packaging tape, is a common packaging product used by light industrial enterprises, companies, and individuals. In daily use, packaging tape adheres smoothly to packaging surfaces. Removing it can be done by cutting the tape with a knife, but this can easily scratch the contents if the cutting depth isn't carefully controlled. Without a knife, one must slowly pry open one end of the tape with their fingernail and then tear it off, which is inefficient. Therefore, there is a need to design a packaging tape that is easier to remove. Utility Model Content

[0004] In order to solve the above problems, this application proposes a sealing tape.

[0005] The purpose of this application is to provide a packing tape that, by changing the structure of the packing tape, divides the adhesive layer of the tape into two parts, with the first adhesive layer as the main adhesive part and the second adhesive layer having circular protrusions. The circular protrusions can provide a supporting effect on the substrate, and this supporting effect makes it easy to disassemble during the removal of the packing tape.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A sealing tape includes: a substrate, a first adhesive layer, and a second adhesive layer. The first adhesive layer is located in the middle of the substrate, and the second adhesive layer is located on both sides of the first adhesive layer. The second adhesive layer is axially symmetrical about the first adhesive layer. A flexible partition is provided between the first adhesive layer and the second adhesive layer. The second adhesive layer has circular protrusions that are bonded to the substrate. The circular protrusions are made of rigid plastic particles. The height of the circular protrusions is greater than the thickness of the first adhesive layer. The surface of the circular protrusions is covered with adhesive glue, so that the second adhesive layer will have an uneven surface due to the circular protrusions.

[0008] Furthermore, there are multiple circular protrusions, and each circular protrusion is independently distributed in the second adhesive layer.

[0009] Furthermore, the flexible partition is perpendicular to and fixedly connected to the substrate surface, which separates the first adhesive layer and the second adhesive layer, preventing the circular protrusions of the second adhesive layer from affecting the adhesion of the first adhesive layer.

[0010] Furthermore, it also includes a support layer composed of mesh-like fiber filaments, which is fixedly connected to the side of the substrate away from the first adhesive layer.

[0011] Furthermore, it also includes a release layer, wherein the sides of the first adhesive layer and the second adhesive layer away from the substrate are bonded to the release layer, the release layer is made of release paper, and the width of the release layer is greater than the width of the substrate.

[0012] Furthermore, the width of the second adhesive layer is smaller than the width of the first adhesive layer.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] 1. This application modifies the structure of the packing tape by dividing the adhesive layer of the tape into two parts, with the first adhesive layer as the main adhesive part and the second adhesive layer having circular protrusions. The circular protrusions can provide support for the substrate, and this support effect makes it easy to disassemble during the removal of the packing tape.

[0015] 2. In this application, the height of the circular protrusion is slightly higher than the thickness of the second adhesive layer. This way, after the second adhesive layer is adhered to the packaging surface, the side of the circular protrusion away from the substrate will adhere to the packaging. There is a certain gap between the second adhesive layer and other parts of the substrate. When removing the sealing tape, the distance between the substrate and the packaging can be easily increased through this gap, which makes the sealing tape easy to remove.

[0019] The present application will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0020] A type of sealing tape, such as Figures 1-2As shown, it includes: a substrate 1, a first adhesive layer 2, and a second adhesive layer 3. The first adhesive layer 2 is located in the middle of the substrate 1, and the second adhesive layer 3 is located on both sides of the first adhesive layer 2. The second adhesive layer 3 is axially symmetrical about the first adhesive layer 2. A flexible partition 5 is provided between the first adhesive layer 2 and the second adhesive layer 3 to separate the first adhesive layer 2 and the second adhesive layer 3. The second adhesive layer 3 has a circular protrusion 4, which is bonded to the substrate 1. The circular protrusion 4 is a hard plastic particle, and the height of the circular protrusion 4 is greater than the thickness of the first adhesive layer 2. The surface of the circular protrusion 4 is covered with adhesive glue, so the second adhesive layer 3 will have an uneven state due to the circular protrusion 4.

[0021] When using the sealing tape, align the first adhesive layer 2 with the seam or opening of the packaging and apply it. Then, apply the second adhesive layer 3 to the flat surface of the packaging. The first adhesive layer 2 seals the packaging, and the second adhesive layer 3 also has some adhesion. However, the circular protrusions 4 in the second adhesive layer 3 contact the packaging surface, leaving a gap between the part of the second adhesive layer 3 that does not contact the packaging surface. When removing the sealing tape, the hard feel of the circular protrusions 4 and the gap between the second adhesive layer 3 and the packaging make it easy to tear open the second adhesive layer 3. With the tear-open gap in the second adhesive layer 3, the first adhesive layer 2 can be torn open, making it easy to remove the sealing tape as a whole.

[0022] like Figure 2 As shown, there are multiple circular protrusions 4, and each circular protrusion 4 is independently distributed in the second adhesive layer 3, which facilitates the removal of the substrate 1 from the packaging.

[0023] The flexible partition 5 is perpendicular to and fixedly connected to the surface of the substrate 1, which separates the first adhesive layer 2 and the second adhesive layer 3 and prevents the circular protrusion 4 of the second adhesive layer 3 from affecting the adhesion of the first adhesive layer 2. Both the flexible partition 5 and the substrate 1 are made of biaxially oriented polypropylene film, and the adhesive of the first adhesive layer 2 and the second adhesive layer 3 is made of acrylic adhesive.

[0024] like Figure 1 As shown, it also includes a support layer 6, which is composed of mesh fibers. The support layer 6 is fixedly connected to the side of the substrate 1 away from the first adhesive layer 2, so as to prevent the substrate 1 from tearing during the tearing process. Through the reinforcement of the support layer 6, the sealing tape will not break during the removal process, thus improving the overall strength of the sealing tape.

[0025] like Figure 1As shown, it also includes a release layer 7. The side of the first adhesive layer 2 and the second adhesive layer 3 away from the substrate 1 is bonded to the release layer 7. The release layer 7 is made of release paper. The width of the release layer 7 is greater than the width of the substrate 1. In this way, the release layer 7 can protect the first adhesive layer 2 and the second adhesive layer 3 and prevent them from being damaged before the sealing tape is used.

[0026] like Figure 2 As shown, the width of the second adhesive layer 3 is smaller than the width of the first adhesive layer 2, which can increase the main bonding area of ​​the sealing tape and ensure the bonding effect.

[0027] In the technical solution of this application, by changing the structure of the packing tape, the adhesive layer of the tape is first divided into two parts, with the first adhesive layer 2 as the main adhesive part. The two sides of the first adhesive layer 2 are provided with the second adhesive layer 3. The second adhesive layer 3 has circular protrusions 4, which are made of hard plastic particles, which can support the substrate 1 and facilitate the removal of the substrate 1 from the packaging surface. The height of the circular protrusions 4 is slightly higher than the thickness of the second adhesive layer 3. In this way, after the second adhesive layer 3 is adhered to the packaging surface, there will be a certain gap between the packaging and the second adhesive layer 3, which is convenient to tear off when removing the packing tape. Finally, the support layer 6 supports the substrate 1 to prevent the packing tape from tearing the substrate 1 when it is removed. In this way, it is easy to tear off the packing tape and improves the efficiency of removing the packing tape.
