[0014] Compared with the prior art, the beneficial effects of this utility model are: This easy-tear Teflon tape:

[0015] 1. This device has an easy-tear area on the surface of the base fabric layer. The easy-tear area has two symmetrical trapezoidal protrusions. The easy-tear line is formed by cutting the surface of the easy-tear area with a die-cutting machine. Users can easily apply force along the easy-tear line to tear the tape. The trapezoidal protrusions in the easy-tear area make it easy for users to tear the tape again.

[0016] 2. The easy-tear zones of this device are evenly spaced on the surface of the base fabric layer. The easy-tear zones allow for convenient tearing of the tape, and the length of the torn tape can be quickly determined based on the arrangement of the easy-tear zones, making the use of the tape convenient.

[0017] 3. This device has two long strips of release paper symmetrically arranged below the adhesive layer as a separator layer, and the separator layer is aligned with the trapezoidal protrusion of the easy-tear area. When the tape is used, the separator layer can separate the adhesive layer from the easy-tear area, making it easy to peel off the trapezoidal protrusion of the easy-tear area and making it convenient to use.

[0023] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: an easy-tear Teflon tape, comprising a base fabric layer 1, an adhesive layer 2, a separator layer 3, an easy-tear area 4, and an easy-tear line 5.

[0025] The base fabric layer 1 is made of polytetrafluoroethylene film. The base fabric layer 1 is extruded into a film shape by an extruder. An adhesive layer 2 is provided below the base fabric layer 1. The adhesive layer 2 is formed by applying adhesive to the lower surface of the base fabric layer 1 using a coating device. A separator layer 3 is provided below the adhesive layer 2. The separator layer 3 is a strip of release paper. The separator layer 3 is attached to the surface of the adhesive layer 2. Two separator layers 3 are symmetrically arranged on the lower surface of the adhesive layer 2. An easy-tear area 4 is provided on the surface of the base fabric layer 1. The easy-tear area 4 consists of two symmetrical trapezoidal protrusions. The two trapezoidal protrusions of the easy-tear area 4 are connected by an elongated structure. The easy-tear areas 4 are equidistantly arranged on the surface of the base fabric layer 1. The trapezoidal protrusions of the easy-tear area 4 are aligned with the separator layer 3. An easy-tear line 5 is provided on the surface of the easy-tear area 4. The easy-tear line 5 is set along the contour of the easy-tear area 4 and is formed by cutting with a die-cutting machine.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using the tape, locate the tear line 5 formed by the die-cutting machine on the surface of the tape. Hold the trapezoidal protrusion of the tearable area 4. Since the trapezoidal protrusion of the tearable area 4 is aligned with the separator layer 3 set on the lower surface of the adhesive layer 2, the trapezoidal protrusion of the tearable area 4 can be easily peeled off. Pinch the trapezoidal protrusion of the tearable area 4 and tear it along the direction of the tear line 5. The tear line 5 reduces the difficulty of tearing and makes the tearing process easier. After tearing, remove the separator layer 3 to expose the adhesive layer 2. Stick the tape to the desired position and press it firmly to adhere it.

[0027] Working principle: When using this easy-tear Teflon tape, the trapezoidal protrusion of the easy-tear area 4 is used to easily peel off one end of the tape, and the tape is torn along the easy-tear line 5 on the surface of the easy-tear area 4, which reduces the difficulty of tearing the tape. After tearing, the separator layer 3 is removed, and the tape is pasted in the required position using the adhesive layer 2. The equidistant easy-tear areas 4 can quickly determine the length of the tape, increasing the overall practicality.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
