Description

Anti-counterfeiting label with double matrixes and anti-counterfeiting method

Technical Field

The application belongs to the technical field of anti-counterfeiting, and particularly relates to an anti-counterfeiting label and an anti-counterfeiting method adopting metal fibers with high elastic deformation strength.

Background

With the development of economy and the progress of modern science and technology, the traditional anti-counterfeiting technology cannot meet the requirement of high-tech anti-counterfeiting.

The traditional anti-counterfeiting means are fluorescent fiber, laser labels, inquiry type digital anti-counterfeiting labels, texture anti-counterfeiting labels, electronic radio frequency label technology and the like.

Fluorescent fibers: the threshold is prevented from being extremely low, and the anti-counterfeiting effect is difficult to achieve.

Laser labeling: the consumer also has no ability to identify the authenticity of the label, the label is easy to forge, and under the condition of lacking the comparability, 60 percent of counterfeits and 100 percent of genuine products are difficult to be distinguished; secondly, the temperature change label is easy to identify but is easy to forge by consumers.

Inquiry type digital anti-counterfeit label: the consumer can inquire the authenticity of the digital label through a telephone, a short message and the Internet, but the anti-counterfeiting digital code is only printed on the surface of the paper, so the anti-counterfeiting digital label is easy to forge.

Texture anti-counterfeit label: the texture anti-counterfeiting technology is an anti-counterfeiting technology which takes speckle marks inherent to the packaging material as anti-counterfeiting identification marks. The consumer can inquire the file and distinguish the true from the false through internet, fax and telephone. The counterfeiting difficulty is improved in a random principle. But mass recognition is more difficult.

Electronic radio frequency tag technology: by attaching the RFID anti-counterfeiting label to products, packages and the like, consumers can automatically scan by using RFID reading equipment to identify the true and false, and the consumers can really feel relieved and feel comfortable to purchase after the anti-counterfeiting label is combined with texture anti-counterfeiting and safety line anti-counterfeiting. RFID is difficult to counterfeit but requires specialized instrumentation to identify.

In summary, there is a continuing need in the anti-counterfeiting field to develop more secure, reliable, and easily identifiable anti-counterfeiting technologies.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

In the present application, each term has a meaning generally understood in the art, unless otherwise indicated or a different meaning can be derived from the context.

The term "tensile strength" in the present application refers to the ability of a material to resist permanent deformation and failure under an external force, and the maximum tensile stress to which a sample is subjected until breaking in a tensile test is the breaking tensile strength. The greater the tensile strength in the elastic deformation zone, which means the greater the resistance of the material to bending deformation within the elastic limit, the tensile strength is determined according to GB/T228.1-2010 "part 1 of the tensile test for metallic materials: the measurement was carried out by the method in Room temperature test method.

As shown in fig. 2, the stress-strain curve of a metal material is divided into an elastic stage and a plastic stage. In the elastic phase, the stress is proportional to the strain of the specimen, the stress is removed and the deformation disappears, i.e. the specimen is in the elastic deformation phase, and the yield point σ y is the elastic limit of the material, which represents the maximum stress at which the material remains fully elastically deformed. After the yield point is exceeded, the stress is continuously applied, and if the stress is unloaded, the deformation of the sample can only be partially recovered, and a part of residual deformation, namely plastic deformation, is remained, which indicates that the deformation of the metal enters an elastic-plastic deformation stage.

FIG. 3 is a stress-strain curve of amorphous fiber. As shown, the results of testing different diameter CoFeSiB amorphous fibers, sample 1 diameter 100 microns and sample 2 diameter 30 microns. The amorphous fiber is almost in an elastic deformation area in the whole stretching process. The maximum tensile strength which can be borne by the two amorphous fiber samples after elastic deformation is kept is higher than 600 MPa. Amorphous fibers are a preferred material of the present invention.

The application provides a label in one aspect, it includes first base member, one or more straight fibre that has metallic luster and second base member, the fibre has first end and second end, fibrous first end with first base member is connected, fibrous second end with the second base member is connected, fibrous diameter is 1 to 300 microns, the maximum tensile strength that can bear when the fibre is in the elastic deformation zone is for more than or equal to 300 MPa. The inventors of the present application have unexpectedly found that in the case where the maximum tensile strength that the fiber can withstand when it is in the elastically deformed region is large, the fiber can recover almost completely after being temporarily bent without permanent bending.

In some embodiments, the fibers can withstand a maximum tensile strength of 600MPa or greater, 700MPa or greater, 800MPa or greater, 900MPa or greater, 1000MPa or greater, 1200MPa or greater, 1500MPa or greater, 2000MPa or greater, 2500MPa or greater when in the elastically deformed region. The greater the maximum tensile strength parameter that the fiber can withstand when it is in the elastically deformed region, the more pronounced the "ability to recover almost completely without permanent buckling" exhibited by the fiber after being temporarily buckled.

In some embodiments, the length of the fibers between the first and second matrices is from 1 to 100mm, such as from 2 to 50mm, such as from 3 to 30mm, such as from 5 to 10 mm.
