Problems solved by technology

But, the adhesive layer of its adhesive tape of existing product is to be coated on the release paper layer continuously and evenly when producing, and in actual use, see Figure 8 ~ Figure 9 As shown, the adhesive layer of the tape moves back with the pressure of the head of the tape box on the surface of the paper or object, and it breaks away from the connection with the release paper layer and transfers to the surface of the paper or object. When it reaches the predetermined position, Lifting the tape box up will break the adhesive layer film, but due to the elongation of the adhesive layer film, it is easy to cause glue dragging and stringing during the breaking process, which will cause poor positioning of the glue coating position, and even pollute the desired surface. Attached paper or object surface

Embodiment 1

[0016] Embodiment 1: see Figure 1 ~ Figure 2 As shown, the double-sided adhesive tape of the present invention comprises the release paper that adopts the belt substrate layer 11 of plastic film or fiber paper tape and the upper release layer 12 and the lower release layer 13 that are coated and connected on its upper and lower surfaces Layer 1, the upper surface of the release paper layer 1 is coated and connected with an adhesive layer 2, the above is the prior art, and its distinguishing feature is that: the upper surface of the release paper layer 1 is coated with a connected adhesive layer 2. It is composed of hexagonal pressure-sensitive adhesive dots 21 with the same thickness and equidistant distribution. The thickness of the pressure-sensitive adhesive dots 21 is selected within the range of 0.01-0.1 mm, and the size of the side length is selected within the range of 0.25-1 mm. , the distance between the periphery of each pressure-sensitive adhesive dot 21 is selecte...

Embodiment 2

[0018] Example 2: see image 3 As shown: the adhesive layer 2 coated and connected to the upper surface of the release paper layer 1 is composed of square pressure-sensitive adhesive dots 21 arranged equidistantly with the same thickness, and the thickness of the pressure-sensitive adhesive dots 21 is between 0.01 and Choose within the range of 0.1 mm, choose the side length of the size within the range of 0.8-2 mm, and select the distance between the periphery of each pressure-sensitive adhesive point 21 within the range of 0.2-0.8 mm.

Embodiment 3

[0019] Embodiment 3: see Figure 4 As shown: the upper surface of the release paper layer 1 is coated and connected with the adhesive layer 2, which is composed of equidistant triangular pressure-sensitive adhesive dots 21 with the same thickness, and the thickness of the pressure-sensitive adhesive dots 21 is 0.01 Choose within the range of ~0.1mm, choose the size of the side length of the equilateral triangle within the range of 0.8~2mm, and choose the distance between the periphery of each pressure-sensitive adhesive point 21 within the range of 0.2~0.8mm.

Abstract

The invention discloses a double-sided adhesive tape which comprises a matrix layer and a release paper layer comprising an upper anti-adhesive layer and a lower anti-adhesive layer which are connected with an upper coated surface and a lower coated surface thereof, wherein, the upper surface of the release paper layer is coated and connected with an adhesive layer. The double-sided adhesive tape is characterized in that: the adhesive layer comprises pressure-sensitive adhesive dots arranged in regular intervals with equal thickness. As the adhesive layer of the double-sided adhesive tape is designed into a dot-type adhesive-layer structure, when in use, an adhesive film of the adhesive layer is easy to break when a tape box of a coater is lifted, thereby overcoming the problem of pulling and drawing the adhesive layer easily occurred in the usage of the existing double-sided adhesive tape, and ensuring the order and cleanness in the coating of the adhesive film.

Description

technical field [0001] The invention relates to a double-sided adhesive tape in stationery, in particular to a double-sided adhesive tape which is made into a core shape and installed in a box body of an applicator. Background technique [0002] At present, a kind of double-sided adhesive tape that is made into a core shape and used in the applicator box is widely used in the bonding of paper or objects because of its ease of use. But, the adhesive layer of its adhesive tape of existing product is to be coated on the release paper layer continuously and evenly when producing, and in actual use, see Figure 8 ~ Figure 9 As shown, the adhesive layer of the tape moves back with the pressure of the head of the tape box on the surface of the paper or object, and it breaks away from the connection with the release paper layer and transfers to the surface of the paper or object. When it reaches the predetermined position, Lifting the tape box up will break the adhesive layer film, ...
