Description

Easily tear double-sided tape

Technical Field

The utility model relates to the technical field of adhesive tapes, in particular to an easy-to-tear double-sided adhesive tape.

Background

The double-sided adhesive tape is a roll-shaped adhesive tape which is prepared by using paper, cloth and a plastic film as base materials and uniformly coating an elastomer pressure-sensitive adhesive or a resin pressure-sensitive adhesive on the base materials, and consists of the base materials, an adhesive, release paper (film) or silicone oil paper. The existing double-sided adhesive tape structure is inconvenient when the release paper on the surface is torn, and the release paper needs to be repeatedly pulled away, so that the double-sided adhesive tape structure is too troublesome when in use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an easy-to-tear double-sided adhesive tape to solve one or more problems in the background art.

In order to achieve the purpose, the utility model adopts the following scheme: the utility model provides an easily tear double-sided tape, is including a rolling section of thick bamboo and twine the sticky tape on the rolling section of thick bamboo, the sticky tape is including the adhesive layer with from the type layer be equipped with a plurality of first easy grooves that tear along its length direction interval on the adhesive layer be equipped with a plurality of second easy grooves that tear along its length direction interval on the type layer, first easy groove and the second of tearing easily tear the groove interval and set up, and first easy groove that tears is located the rear side that the second easily torn the groove.

Furthermore, the both sides in first easy tear groove all are equipped with first V-arrangement and lack the groove.

Furthermore, the second V-shaped notch is arranged on both sides of the second easy-tearing groove.

Further, first easily tear the groove and easily tear the groove with the second on equal interval be equipped with a plurality of through-holes.

Further, the distance between the first easy-tearing groove and the second easy-tearing groove is 1-3 mm.

Further, the width of the adhesive layer is smaller than that of the release layer, and two sides of the release layer extend out of two sides of the adhesive layer to form an easy-tearing area.

Further, the width of the easy tearing area is 0.5-1 mm.

Further, the adhesive layer comprises a first pressure-sensitive layer, a substrate layer and a second pressure-sensitive layer which are sequentially arranged.

In summary, the beneficial effects of the utility model are as follows: when the tape-stripping needs to be torn, the tape can be easily torn by the second easy-tearing groove on the release layer and the first easy-tearing groove on the adhesive layer, and after tearing, because the first easy-tearing groove is located at the rear side of the second easy-tearing groove, the end of the release layer can be provided with more adhesive layers, so that the tape-stripping layer can be conveniently torn, and the use convenience of the tape is improved.

Detailed Description

The following detailed description provides many different embodiments or examples for implementing the utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. In addition, repeated reference numbers, such as repeated numbers and/or letters, may be used in various embodiments. These iterations are for simplicity and clarity of describing the present invention and are not intended to represent a particular relationship between the various embodiments and/or configurations discussed.

The utility model is further described in the following description of the drawings and the detailed description: the easy-to-tear double-sided adhesive tape shown in fig. 1 to 2 comprises a winding drum and an adhesive tape wound on the winding drum, wherein the adhesive tape comprises an adhesive layer 1 and a release layer 2, a plurality of first easy-to-tear grooves 3 are arranged on the adhesive layer 1 at intervals along the length direction of the adhesive layer, a plurality of second easy-to-tear grooves 4 are arranged on the release layer 2 at intervals along the length direction of the release layer, the first easy-to-tear grooves 3 and the second easy-to-tear grooves 4 are arranged at intervals, and the first easy-to-tear groove 3 is positioned at the rear side of the second easy-to-tear groove 4, when the adhesive tape is adhered and needs to be torn, the adhesive tape can be easily torn off through the second easy-tearing groove 4 on the release layer 2 and the first easy-tearing groove 3 on the adhesive layer 1, and after the adhesive tape is torn off, because first easy groove 3 of tearing is located the second and easily tears the rear side of groove 4, consequently, can go out the tip of adhesive layer 1 more from the tip on type layer 2 to the convenience is torn off type layer 2 and is left, has improved the convenience that the sticky tape used.

Specifically, the adhesive layer 1 includes a first pressure-sensitive layer 81, a base material layer 82, and a second pressure-sensitive layer 83, which are sequentially disposed.

In the utility model, the two sides of the first easy-to-tear groove 3 are both provided with the first V-shaped notch grooves 21, and the two sides of the second easy-to-tear groove 4 are both provided with the second V-shaped notch grooves 31, so that the adhesive layer 1 and the release layer 2 can be conveniently torn.

Specifically, first easy groove 3 and the second of tearing are easily torn all the interval and are equipped with a plurality of through-holes 41 on groove 4, need tear sticky tape 1 in the use, find adjacent first easy groove 3 and the second of tearing easily tear groove 4, easily tear groove 4 department at first easy groove 3 and the second of tearing, because first easy groove 3 and the second of tearing easily tear groove 4 department by the structure of extrusion and through-hole 41 for first easy groove 3 and the second of tearing easily tear groove 4 and compare in sticky tape 1 other positions and tear more easily, and the fracture parallel and level, do not influence follow-up use.
