Description

Technical Field

[0001] The utility model belongs to the technical field of release paper, and in particular relates to an easy-to-tear release paper and a double-sided adhesive tape thereof. Background Art

[0002] Release paper is a kind of anti-adhesive paper, which is widely used in industrial manufacturing and process processing materials. It is suitable for various self-adhesive materials, double-sided tapes, advertising materials, electronic die-cutting, etc. In the field of tapes, the most commonly used double-sided tape is a release paper that is an indispensable component. The release paper used on the double-sided tape is not easy to tear off when in use. After being torn off forcefully, its end is wrinkled, which affects the subsequent adhesion. In order to facilitate the tearing of the release paper, Chinese patent CN202222507280.8 discloses an integral easy-to-tear release paper, in which a pinhole strip is arranged on the surface of the release paper body. The setting of the pinhole strip facilitates the tearing of the anti-adhesive paper, but it also brings a disadvantage, that is, the pinhole strip will cause the tensile strength of the release paper to decrease, and the release paper is easy to break when in use, and is not tensile-resistant. For this reason, we propose a tensile-resistant and easy-to-tear release paper. Utility Model Content

[0003] The utility model aims to solve the shortcoming of the easy-tear release paper provided with pinhole strips in the prior art that the tensile strength is insufficient, and proposes an easy-tear release paper.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An easy-to-tear release paper is designed, comprising a paper base layer, wherein an upper isolation film layer and a lower isolation film layer are connected on both sides of the paper base layer by an adhesive layer, and the outer sides of the upper isolation film layer and the lower isolation film layer are coated with a silicone oil coating. The invention is characterized in that the upper isolation film layer is provided with upper cutting dotted lines equidistantly along the length direction, and the lower isolation film layer is provided with lower cutting dotted lines equidistantly along the length direction.

[0006] Furthermore, the upper cutting dotted line and the lower cutting dotted line are correspondingly arranged on both sides of the paper base layer.

[0007] Furthermore, the upper cutting dotted lines and the lower cutting dotted lines are alternately arranged on both sides of the paper base layer, so that the upper cutting dotted lines and the lower cutting dotted lines are equidistantly arranged along the length direction of the paper base layer.

[0008] A double-sided adhesive tape adopts the easy-tear release paper, the easy-tear release paper is provided with a double-sided adhesive layer, and the double-sided adhesive layer is provided with adhesive layer cutting dotted lines equidistantly along the length direction.

[0009] The utility model provides an easy-to-tear release paper, which has the beneficial effect that: the utility model adopts an upper isolation film layer and a lower isolation film layer in combination, and cutting dotted lines are respectively provided on the upper isolation film layer and the lower isolation film layer. After gluing, no penetrating cutting dotted lines are formed on the release paper, so that the release paper is not easy to break and has good tensile resistance.

[0010] (1) The utility model provides the cutting imaginary lines in a staggered manner. Under the premise that the release paper has good tensile resistance, the release paper can be easily torn off along any adjacent cutting imaginary lines on both sides.

[0011] (2) When the present invention is torn, a fracture will appear between two adjacent cutting dotted lines, and the appearance of the fracture can make it easier to peel the release paper from the double-sided adhesive layer. BRIEF DESCRIPTION OF THE DRAWINGS
