Anti counterfeiting label: there are many ways to improve the security of the label by fully applying the manual
the security technology used on the label mainly depends on the purpose of the label, the desired security level and the objects endangering the security of the label, such as forgery or fakes. In order to achieve the desired security level, several security technologies need to be applied at the same time in most cases. Several anti-counterfeiting labels are briefly introduced below
anti theft tag
anti theft tag will leave theft information on the surface. After the label is torn off, the words "void" or "opened" will appear, which will explain to the user that the product has been stolen before. It can also be used to prevent people from illegally transferring or stealing corporate assets, such as computer hardware and other equipment. Customers can customize tags with special information, that is, display a special phrase after the tag is stolen

another anti-theft label is a label that can prevent cutting and resealing. After the label is torn off, the stolen information will appear at the pasting place of the label. It also has a special function: if the label is not torn off, but is cut off and re sealed, the stolen information will not appear immediately, but will appear one hour later
Figure 2: after the label is cut, it is more and more sealed by the innovative research and development of cutting-edge products and technologies, and a warning message will appear one hour later, indicating that the label has been stolen
this anti pilferage label is especially suitable for sealing small containers and packages. If it is used as a label to identify parts and equipment, it can also prevent pilferage and theft. Such anti-counterfeiting labels are applicable to products such as pharmaceuticals, electronic products, warehouse management safety facilities, baby food and retail products
fragile labels
fragile labels are made of materials that are very easy to tear. After being torn off, the label cannot be replaced by another label. If you want to tear off the label, it will only tear the label to pieces, and the authorized user of the product can easily know whether the label has been stolen. They can prevent theft, theft and unauthorized transfer of corporate assets. They can also be used in drugs and other safety related products

currently there are fragile labels with consecutive numbers on the market. Customers can also purchase labels without consecutive numbers and code the labels themselves. The barcode label can also be used as 1 Fragile label of test fixture
holographic labels and new composite materials such as carbon fiber are also driving the growth of all composite materials.
holograms can provide a good anti-counterfeiting function for labels because they are difficult to copy. Holograms can be added to a variety of labels, which can not only improve the anti-counterfeiting performance of products, but also be used for product promotion.
the application fields using holograms as anti-counterfeiting means include drugs, retail, credit cards, ID cards, various certificates and bills. At present, there are standard designed holograms in the market, and customers can also customize special holographic effects
anti counterfeiting bar code
labels with anti counterfeiting bar code cannot be copied with a copier. The back of the label is made of black composite material and adopts dyes that do not absorb infrared rays. The barcode is printed on the film label with carbon ink that can absorb infrared ray. In the barcode area, the naked eye cannot see it, but the carbon ink information that has absorbed light can be read through the infrared scanner. Under the scanner, the bar code is black and the background is white. This anti-counterfeiting bar code is mostly used on employee certificates and anti-counterfeiting badges
anti counterfeiting ink
thermochromic ink can be used to print labels of products that need to be stored at a predetermined temperature or in a specific environment. The specific gray or color shadow displayed can prove whether the product is properly stored under appropriate temperature conditions
eas tag
eas (electronic anti-theft system) tag can be used for anti-theft devices as the name suggests. When used with EAS anti-theft equipment, it can be used to detect whether items have been moved without authorization. EAS system can be used in stores, data centers or libraries. When the article is attached with the label, if the label is not properly deactivated, a warning will be issued when it passes through the electronic anti-theft detector. When the articles are normally purchased or legally moved, the EAS label is deactivated through the device so that the articles can be taken away smoothly
there are many technologies for EAS tags. The most common are am (acousto magnetic), EM (electro magnetic) and RF (radio frequency). The AM EAS system uses a transmitter to form a specific monitoring area. If the tag is not legally deactivated, the articles with EAS tags will send an alarm when they pass through the monitoring area and use rigid polyurethane reinforced coiled material composite insulation board. The EM EAS system uses low-frequency electromagnetic fields to form a monitoring area. The RF EAS system uses radio frequencies to form a monitoring area. Each EAS system requires different monitoring equipment
however, only reasonable application of EAS tags and EAS systems can effectively prevent items from being stolen
micro tracking particles
micro tracking particles are molecular structures that can be arranged in a unique order according to the situation of customers. They can be made into paper or film, and then made into labels, which can be used to identify or identify objects. The authenticity of labels can be identified using e-readers. Therefore, the tag containing micro tracking particles is a high-level anti-counterfeiting tag, which is very expensive. The cost of the reader alone is more than 5000 dollars
