Abstract

The utility model discloses a tear RFID label that destroys promptly. The invention relates to an electronic tag, in particular to an improvement of a radio frequency electronic tag. The destruction is easy, and the stability of the first use of the RFID tag is not influenced. Including substrate layer, aluminium foil layer and RFID chip, the aluminium foil layer with the RFID chip is arranged in proper order between the substrate layer, be equipped with fragile membrane between substrate layer and the aluminium foil layer, fragile membrane veneer is in the substrate layer with between the aluminium foil layer. The presence of a small amount of pulling during application still ensures that the structure of the RFID chip is not damaged. When the RFID tag needs to be destroyed, the fragile film can be driven to be irreversibly damaged only by tearing the substrate layer vigorously, so that the purpose of damaging the peripheral circuit of the RFID chip can be achieved, and the whole RFID tag loses the identification function to achieve the purpose of damage.

Description

RFID label destroyed by tearing

Technical Field

The utility model relates to an electronic tags especially designs a radio frequency electronic tags's improvement.

Background

At present, the electronic tags used in the market are generally radio frequency tags, namely RFID tags, the tags can be reused after being private, mechanisms for generating radio frequency are not damaged, lawless persons can get the opportunity to use the tags, the safety performance of the radio frequency tags is low, technical personnel who aim at the problem improve the base material of the radio frequency tags, the base material is made of a material easy to tear, but the radio frequency tags are easy to tear when being pasted for the first time due to the characteristic that the base material is easy to tear, the tensile strength of the radio frequency tags is reduced, the defects that the new tags are poor in contact or directly scrapped easily occur when being used for the first time, and the stability of the electronic tags is affected.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a not only easily destroy but also can not influence the RFID label of tearing of the stability that the RFID label used for the first time and destroy promptly.

The utility model discloses a following technical scheme realizes: the utility model provides a tear RFID label that destroys promptly, includes substrate layer, aluminium foil layer and RFID chip, the aluminium foil layer with the RFID chip is arranged in proper order between the substrate layer, be equipped with fragile membrane between substrate layer and the aluminium foil layer, fragile membrane veneer is in the substrate layer with between the aluminium foil layer.

The substrate layer includes substrate layer, surface material layer and PET layer, the chip is located on the aluminium foil layer, aluminium foil layer veneer is in on the PET layer, the PET layer passes through the hot melt adhesive veneer and is in on the surface material layer, the substrate layer passes through the hot melt adhesive veneer and is in the RFID chip surface, fragile membrane is located the aluminium foil layer with between the PET layer and through the hot melt adhesive veneer on the PET layer.

The thickness of the aluminum foil layer is 8-9 μm, and the thickness of the fragile membrane is 5-7 μm.

The thickness of the PET layer is 30-50 μm.

The base material layer and the surface material layer are both adhesive paper layers.

Compared with the prior art, the utility model discloses pressing from both sides the fragile membrane between the substrate layer, both kept the stability of RFID label when using, because the existence of substrate layer, even there is certain tensile properties in the substrate layer when first use, even there is a small amount of structures that drag still can guarantee the RFID chip when pasting to be damaged. When the RFID tag needs to be destroyed, the fragile film can be driven to be irreversibly damaged only by tearing the substrate layer vigorously, so that the purpose of damaging the peripheral circuit of the RFID chip can be achieved, and the whole RFID tag loses the identification function to achieve the purpose of damage.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1. a face material layer; 2. hot melt adhesive; 3. a PET layer; 4. a frangible membrane; 5. an aluminum foil layer; 6. an RFID chip; 7. a substrate layer.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in figure 1, the RFID label destroyed immediately after tearing comprises a substrate layer, an aluminum foil layer 5 and an RFID chip 6, the aluminum foil layer 5 and the RFID chip 6 are sequentially arranged between the substrate layer, a fragile membrane 4 is arranged between the substrate layer and the aluminum foil layer 5, and the fragile membrane 4 is glued between the substrate layer and the aluminum foil layer 5. The fragile film 4 is clamped between the base material layers, so that the stability of the RFID label in use is kept, and even if the base material layer has certain tensile property in the initial use, the structure of the RFID chip 6 cannot be damaged even if the base material layer is slightly pulled in the pasting process. But when the RFID tag needs to be destroyed, the fragile film 4 can be driven to be irreversibly damaged only by tearing the substrate layer vigorously, so that the purpose of damaging the peripheral circuit of the RFID chip 6 can be achieved, and the whole RFID tag loses the identification function to achieve the purpose of damage.

The substrate layer includes base material layer 7, surface material layer 1 and PET layer 3, the chip is located on the

aluminium foil layer

5, 5 plys on the aluminium foil layer are in on the PET layer 3, PET layer 3 is in through hot melt adhesive 2 plys on the surface material layer 1, base material layer 7 is in through hot melt adhesive 2 plys RFID chip 6 surfaces, fragile membrane 4 is located aluminium foil layer 5 with just be in through hot melt adhesive 2 plys between the PET layer 3 on the PET layer 3. Set up PET layer 3 between the substrate layer, PET is a common synthetic resin, regards it as RFID chip 6's carrier, has guaranteed that it can not be broken at certain tension within range fragile membrane 4 when posting the RFID label, and the RFID label accident is destroyed when avoiding normally posting, guarantees the stability of its use. The thickness of the aluminum foil layer 5 is 8-9 μm, and the thickness of the fragile membrane 4 is 5-7 μm. The thickness of the PET layer 3 is 30-50 μm. The base material layer 7 and the surface material layer 1 are both adhesive paper layers. The preferred thickness of the frangible membrane 4 is 6 μm, which does not affect its stability in use for the first time and ensures convenient destruction when required.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
