Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of antenna anti-counterfeiting labels, in particular to a partially fragile silver paste printed antenna anti-counterfeiting label. Background Art
[0002] Partially fragile antenna self-adhesive labels are a type of self-adhesive labels. Their characteristics are that the silver paste of the coating layer is easy to fall off after being pasted, and it cannot be completely separated from the adhesive. Therefore, they cannot be completely peeled off after pasting and cannot be reused. Partially fragile antenna self-adhesive labels are made into partially fragile labels or partially fragile stickers after printing and die-cutting. This type of label is mainly used for the quality assurance needs of some unconventional product identification, because it uses a special coating material that can effectively prevent the warranty label from being tampered with, maliciously replaced, and reused.
[0003] Most of the existing partially fragile silver paste printed antenna anti-counterfeiting labels are made of aluminum etching materials. The etching process produces a large amount of waste liquid containing metals and chemicals, causing great pollution to the environment. In addition, during use, the antenna chip layer is easily affected by bumps and collisions from the external environment, resulting in reduced stability of the label. Utility Model Content

[0013] Figure 2 for Figure 1 A cross-sectional view of an anti-counterfeiting label with a partially fragile silver paste printed antenna is shown. DETAILED DESCRIPTION
[0014] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0015] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.
[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0017] See also Figure 1 and Figure 2, is a partially fragile silver paste printed antenna orientation label of one embodiment of the utility model, comprising a surface paper layer 1, a first self-adhesive layer 2 disposed on the bottom surface of the surface paper layer 1, an antenna chip layer 3 fixedly disposed on the bottom surface of the first self-adhesive layer 2, a coating layer 4 disposed on the bottom surface of the antenna chip layer 3, a substrate layer 5 disposed on the bottom surface of the coating layer 4, a second self-adhesive layer 6 disposed on the bottom surface of the substrate layer 5, and a release paper layer 7 disposed on the bottom surface of the second self-adhesive layer 6. In this embodiment, the antenna chip layer 3 is a silver paste printed antenna chip layer. Through the surface paper layer 1, the first self-adhesive layer 2, the antenna chip layer 3, the coating layer 4, the substrate layer 5, the second self-adhesive layer 6, and the release paper layer 7, the overall stability of the partially fragile silver paste printed antenna anti-counterfeiting label is improved. During work and use, the antenna chip layer 3 will not be damaged by bumps and collisions in the external environment. At the same time, the overall protection capability of the product is also improved. The mutual adhesion between the multiple layers is also smoother, which is convenient for processing and installation operations, thereby improving the applicability of the partially fragile silver paste printed antenna anti-counterfeiting label.
[0018] In this embodiment, the surface paper layer 1 is a PET surface paper layer, a coated paper surface paper layer or a synthetic paper surface paper layer; the surface paper layer 1 has good mechanical strength, temperature resistance, chemical stability and printability, etc., to ensure that the label can operate stably and reliably in various environments.
[0019] In this embodiment, the first self-adhesive layer 2 and the second self-adhesive layer 6 are both high-viscosity self-adhesive layers without a substrate, so that the first self-adhesive layer 2 and the second self-adhesive layer 6 have better adhesion and improved self-adhesion, while also providing a buffering effect to prevent external collisions from affecting the interior.
[0020] In this embodiment, the coating layer 4 is formed of a coating material composed of resin (polyethylene, polyurethane), titanium dioxide and DBE (divalent acid ester). Since the coating is intentionally incompletely covered, that is, the coating material does not completely cover the entire antenna chip 3, a part of the antenna chip layer 3 adheres to the coating layer 4, and the other part of the antenna chip layer 3 adheres to the substrate layer 5. By utilizing the different restraining forces of the coating layer 4 and the substrate layer 5 on the antenna chip layer 3, the silver paste attached to the coating layer 4 is easy to fall off by tearing, while the silver paste attached to the substrate layer 5 is not easy to fall off by tearing, resulting in the chip printed with the silver paste being broken, thereby destroying the use function and achieving the anti-counterfeiting effect.
[0021] Furthermore, the overall structural thickness of the partially fragile silver paste printed antenna anti-counterfeiting label is increased by filling the coating layer 4, and the coating layer 4 has high smoothness, which is convenient for processing and installation.
[0022] In this embodiment, the substrate layer 5 is a PET substrate layer, a PE substrate layer, a PI substrate layer or a PC substrate layer, which has the characteristics of high strength, heat resistance, corrosion resistance, good transparency, etc., and can provide good protection performance. At the same time, its decorativeness and functionality can also be increased through surface printing, coating and other processes.
[0023] In this embodiment, the release paper layer 7 is glassine release paper or PET silicon-coated release film. Glassine release paper or PET silicon-coated release film has good temperature resistance, moisture resistance and oil resistance. The use of the release paper layer 7 composed of glassine release paper or PET silicon-coated release film can prevent the partially fragile silver paste printed antenna anti-counterfeiting label from being easily affected by temperature and environment in the working environment, further improving the stability of adhesion. At the same time, glassine release paper or PET silicon-coated release film also has good release performance, which can be easily peeled off from the base paper without damaging the base paper.
[0024] The above-mentioned partially fragile silver paste printed antenna anti-counterfeiting label simplifies the production process of traditional labels, overcomes the defects of existing methods during manufacturing, and the overall structure has the characteristics of high stability, high precision, and locally fragile and anti-transfer.
[0025] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
