Problems solved by technology
[0004] Most of the fragile paper prepared by the prior art includes a fragile layer and an adhesive layer, and its fracture direction is transverse fracture, such as the fragile paper widely used in the fields of cigarette packs, cosmetics, electronic products, etc.
[0005] However, the fragile paper prepared by the existing preparation method also has its disadvantages, because it is easy to break from the transverse direction, it is inconvenient to operate when pasting, and it will be broken if you don't pay attention to it. , Due to vibration, impact, etc., it is easy to break due to deformation between different parts of the product. In addition, because the existing fragile paper is transversely broken, the paper pulling operation is prone to accidental breakage, and it cannot be automatically collected. Not suitable for batch die-cutting, not suitable for high-volume and automated operations

Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0026] refer to figure 1 , is that the first embodiment of the present invention is a method for preparing fragile paper, comprising the following steps: S(1). Provide face paper, provide vertical fragile film; S(2). Composite on the inner surface of the facial paper; S(3). Coating an adhesive material on the inner surface of the longitudinal fragile film to set up an adhesive layer; S(4). Composite a release layer on the inner surface of the adhesive layer; wherein, the longitudinal fragile layer Including PE particles, the gaps between PE particles are filled with air. In this embodiment, the density of the PE particles is 0.5g / cm 3 and the density of PE particles in the horizontal direction is greater than the density in the vertical direction, and the density in the horizontal direction of PE particles can be realized for 1.1 to 1.5 times of the density...

Abstract
The invention relates to the anti-counterfeiting field, and in particular relates to a preparation method of fragile paper and a device for realizing the method. The preparation method comprises the following step: S(1) providing a facial tissue, and providing a longitudinal fragile film; S(2) compounding the longitudinal fragile film on an inner surface of the facial tissue by a glue; S(3) coating an adhesive material on the inner surface of the longitudinal fragile film to form an adhesive layer; and S(4) compounding releasing layer on the inner surface of the adhesive layer. The preparation device comprises a facial tissue supplying unit, a first gluing unit, a longitudinal fragile film supplying unit, a first compounding unit, a second gluing unit, a releasing paper supplying unit, a second compounding unit and a reeling unit in order.
Description
technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to a method for preparing fragile paper and a device for realizing the method. Background technique [0002] In order to distinguish their products from counterfeit products, merchants often use anti-counterfeiting marks on their products. In order to prevent the goods from being opened in the middle ring, or when the merchant does not want customers to open the package or some fasteners by themselves, anti-counterfeiting marks will also be used. [0003] Fragile paper is a kind of anti-counterfeiting label, and some fragile papers are printed with special signs for merchants. When people open the package or package, the fragile paper will break, so as to achieve the purpose of anti-counterfeiting. [0004] Most of the fragile paper prepared by the prior art includes a fragile layer and an adhesive layer, and its fracture direction is transverse fracture, such as the fragile pape...
