Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, and more specifically, to an edge-sealing adhesive tape. Background Art

[0002] Packaging tape is also called bopp tape, packaging tape, etc. It is based on BOPP biaxially oriented polypropylene film. After heating, the pressure-sensitive adhesive latex is evenly applied to form an adhesive layer ranging from 8μm to 28μm. It is an indispensable product for light industrial enterprises, companies, and personal life. With the development of various industries, tapes are used to package various packaging boxes, and the aforementioned packaging tape is currently the most widely used type of tape. With the diversification of usage needs, the use of tapes is becoming more and more extensive.

[0003] Nowadays, when packaging is performed with tape, there is often a need to tie the tape into a handle to facilitate people to lift objects. However, when the existing packaging tape is tied into a handle to lift objects, it is often pulled and deformed. On the one hand, it is very tight on the hand. On the other hand, as the tape deforms and adheres to one end of the object to be lifted, it will gradually separate from the object to be lifted, resulting in falling off, and the adhesion effect is poor.

[0004] Therefore, it is necessary to design an edge banding tape which has good adhesion effect and does not pinch the hand. Utility Model Content

[0005] The main purpose of the utility model is to provide an edge-sealing tape, aiming to solve the problems of poor adhesion of the edge-sealing tape in the prior art and pinching the hand after deformation.

[0006] In order to solve the above technical problems, an edge-sealing tape is proposed, comprising: a substrate layer, an adhesive layer and a connecting line;

[0007] The substrate layer comprises: a first use portion and a second use portion, wherein the first use portion and the second use portion are provided with a plurality of first tooth portions and a plurality of second tooth portions on mutually adjacent sides thereof, the plurality of first tooth portions and the plurality of second tooth portions are arranged alternately, and a gap is provided between the first tooth portions and the second tooth portions;

[0008] The adhesive layer is coated on the first use portion and the second use portion, the connection line is arranged on the adhesive layer parallel to the direction in which the tape is unfolded, and the connection line is arranged corresponding to the first tooth portion and the second tooth portion.

[0009] In any of the above technical solutions, further, the first use part is provided with a clean area and a glue coating area, and the clean area is located on the side of the surface of the first use part away from the second use part, the area of ​​the first use part other than the clean area is the glue coating area, and the adhesive layer is coated on the glue coating area.

[0010] In any of the above technical solutions, further, the first tooth portion and the second tooth portion are both configured to be rectangular.

[0011] In any of the above technical solutions, further, the substrate layer also includes a connecting portion;

[0012] The connecting portion is integrally provided between the first tooth portion and the second use portion, and / or the connecting portion is integrally provided between the first use portion and the second tooth portion.

[0013] In any of the above technical solutions, further, the number of connecting wires is at least two.

[0014] In any of the above technical solutions, further, the connecting line is arranged on a side of the adhesive layer away from the substrate layer, and a certain distance is left between the connecting line and the surface of the substrate layer.

[0015] In any of the above technical solutions, further, the connecting wire is coated in the adhesive layer.

[0016] In any of the above technical solutions, further, the second use portion is provided with a plurality of side ears;

[0017] The side ears are arranged at intervals from each other on a side of the second use portion away from the first use portion, and the adhesive layer is also applied to the side ears.

[0018] In any of the above technical solutions, further, there is an angle between the extension direction of the side ear portion and the unfolding direction of the tape, and the angle is not equal to 90°.

[0019] The beneficial effects are:

[0020] 1. The edge-sealing tape of the utility model is provided with a base material layer as a first use portion and a second use portion respectively having teeth. On the one hand, the first use portion and the second use portion can be used separately, that is, the first use portion or the second use portion can be torn off through the gap between the two and used separately. On the other hand, the first use portion and the second use portion can be used in combination, and two use modes with and without lines can be provided, which can cope with various use scenarios.

[0021] 2. The new edge-sealing tape is used to set connecting lines on the adhesive layer at the corresponding position of the teeth, which can improve the tensile strength and deformation resistance of the tape on the one hand, and reduce the ability of the cross section to shrink inward when it is pulled and deformed on the other hand. In this way, the edge-sealing tape can still maintain a certain width when it is pulled and deformed, so that when it is used in a lifting scene, the user can lift it on the surface of the tape to avoid strangling his hands; and at this time, the deformation degree of the tape is low, which will not cause large deformation and detachment at the position of the adhered object, ensuring the adhesion effect.
