Abstract
It traces to the source label the utility model relates to a kind of two dimensional code of tamper-evident.The two dimensional code of tamper-evident label of tracing to the source includes protective film layer from top to down, the first adhesive-layer, printing layer, the second adhesive-layer, release layer, transparent film bag, sealant, sealing film; a kind of two dimensional code of tamper-evident of the utility model is traced to the source label; it is strong with label anti-counterfeit information privacy; it is not easy to be decrypted; tamper-evident area can generate certain color after label is lifted; antifalsification label will be unable to reuse, and can prevent fake producer from faking using the true label uncovered.
Description
Technical field
The utility model relates to a kind of label, trace to the source label more particularly to a kind of two dimensional code of tamper-evident.
Background technique
Antifalsification label, which refers to, can paste, print, shift in label subject matter surface or label subject matter packaging and label mark
Object adjunct (such as commodity are listed, business card and antifake certificate card) on, the mark with anti-fake effect.
Common antifalsification label, some method for anti-counterfeit are single, are easy to be decrypted；It is some to be easy to be uncovered, make fake producer can
To be faked using the true label uncovered.
Utility model content
In view of the deficiencies of the prior art, the two dimensional code that the utility model provides a kind of tamper-evident is traced to the source label.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of two dimensional code of tamper-evident is traced to the source label, and the two dimensional code of tamper-evident label of tracing to the source includes setting gradually from top to down
Protective film layer, the first adhesive-layer, printing layer, the second adhesive-layer and release layer, it is characterised in that: be printed in the printing layer
Printed coating, the printed coating include trace to the source two dimensional code area, merchandise news area and tamper-evident area, and the tamper-evident area believes around commodity
Breath area and trace to the source two dimensional code area and along the surrounding of printing layer be arranged, the tamper-evident area include coated on printing layer colour developing coating and
Surrounding and middle part are adhered to the transparent film bag of colour developing coating by third adhesive-layer, fill colourless liquid in the transparent film bag.
In a kind of preferred embodiment that the two dimensional code of tamper-evident provided by the utility model traces to the source label, second viscose glue
Viscous force >=third adhesive-layer viscous force of the first adhesive-layer of viscous force > of layer.
In a kind of preferred embodiment that the two dimensional code of tamper-evident provided by the utility model traces to the source label, the transparent film bag
Tearing strength be less than third adhesive-layer adhesive strength.
In a kind of preferred embodiment that the two dimensional code of tamper-evident provided by the utility model traces to the source label, the colour developing coating
For phenolphthalein coating, the interior colourless liquid filled of the transparent film bag is weak base.
Compared with prior art, the trace to the source beneficial effect of label of the two dimensional code of tamper-evident provided by the utility model is: passing through
Two dimensional code of tracing to the source is set in printing layer, two-dimension code anti-counterfeit technical know-how is strong, can store a large amount of anti-counterfeiting information, make fake producer
It is difficult to decode；By filling colourless weak caustic solution inside transparent film bag, applying phenolphthalein in tamper-evident area, when label is lifted, due to
The viscous force of viscous force≤first adhesive-layer viscous force < second station glue-line of the tearing strength < third adhesive-layer of transparent film bag is transparent
Film bag takes the lead in rupturing, and the weak caustic solution inside transparent film bag flows on the phenolphthalein coating in tamper-evident area, then becomes red, thus anti-
Only fake producer is faked using the true label uncovered.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is that the two dimensional code of tamper-evident provided by the utility model is traced to the source the structural schematic diagram of label.
Fig. 2 be tamper-evident provided by the utility model two dimensional code trace to the source label printing layer upper surface top view.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
Also referring to Fig. 1 and Fig. 2, the two dimensional code of tamper-evident label of tracing to the source includes the protection set gradually from top to down
Film layer 1, the first adhesive-layer 2, printing layer 3, the second adhesive-layer 4 and release layer 5 are printed with printed coating in the printing layer 3, institute
Stating printed coating includes trace to the source two dimensional code area 31, merchandise news area 32 and tamper-evident area 33, and the tamper-evident area 33 surrounds merchandise news
Area 32 and tracing to the source and is arranged two dimensional code area 31 along the surrounding of printing layer 3, and the tamper-evident area 33 includes the colour developing coated on printing layer 3
Coating 331 and surrounding and middle part are adhered to the transparent film bag 333 of colour developing coating 331, the hyaline membrane by third adhesive-layer 332
Colourless liquid 3331 is filled in bag 333.
Viscous force >=third adhesive-layer 332 viscous force of the first adhesive-layer of viscous force > 2 of second adhesive-layer 4.
The tearing strength of the transparent film bag 333 is less than the adhesive strength of third adhesive-layer 332.
The colour developing coating 331 is phenolphthalein coating, and the colourless liquid 3331 filled in the transparent film bag 333 is weak base,
Certainly, the utility model is limited to this, and the colourless liquid 3331 and display coating 331 can also be that can produce certain after other are mixed
Two kinds of substances of kind color.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass similarly includes within the scope of patent protection of the utility model.
