Embodiment Construction

[0036] The present application will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings. The "front", "rear", "left", "right", "upper" and "lower" mentioned in the text all refer to the placement state of the easy-to-open tab in the drawings.

[0037] Such as figure 1 and figure 2 As shown, the embodiment of the present application provides an easy pull sheet 1 including a base material layer 10 and an adhesive layer 12 . Wherein, the base material layer 10 is the main structure of the easy-open sheet 1 . The substrate layer 10 includes a plurality of coated areas 100 and easy-to-tear lines 102. These coated areas 100 will be adjacent to each other along the same direction, generally the length direction of the substrate layer 10, and the easy-to-tear lines 102 are used as two adjacent The separation lines between the coating areas 100 exist between all adjacent coating areas 100 , and when there is more than ...

Abstract

The invention relates to the technical field of adhesion supplies, in particular to a zip-top piece which comprises a substrate layer and glue layers. The substrate layer comprises multiple coating areas and easy-to-tear lines, the coating areas are sequentially connected adjacently along a same direction, each two adjacent coating areas are separated through one easy-to-tear line, all easy-to-tear lines are arranged parallelly, one glue layer is coated on one side surface of each coating area, and the glue layers on each two adjacent coating areas are positioned on two opposite sides of the substrate layer respectively. The glue layers are coated on the two adjacent sides of each two adjacent coating areas separated by the corresponding easy-to-tear line, so that when in normal use, the zip-top piece can effectively prevent a battery from being separated from a cellphone; when a tear force is applied along the extending direction of the easy-to-tear lines, adjacent coating areas are highly prone to mutual separation and are adhered on parts fitted therewith, so that the circumstance that a battery body is damaged and cannot be utilized any more when the battery is demounted is avoided.

Description

technical field [0001] The present application relates to the technical field of adhesive supplies, in particular to an easy-to-pull sheet. Background technique [0002] In related technologies, it is often necessary to fix two objects together. For example, a built-in battery of a mobile phone product is usually pasted inside the mobile phone by double-sided tape. [0003] However, due to the strong adhesiveness of the double-sided adhesive tape, the battery body is often damaged when the battery is disassembled and cannot be reused, resulting in waste of cost and safety issues. Contents of the invention [0004] The application provides an easy-to-pull sheet, which can effectively prevent the battery from being damaged due to excessive adhesion when it is separated from products such as mobile phones. [0005] An easy-to-pull sheet provided by the application includes a substrate layer and an adhesive layer; [0006] The substrate layer includes a plurality of coated a...
