The application of labels in the field of anti-counterfeiting (I)

the past 2003 was a remarkable year for the world label industry. The European label printing exhibition was held in Brussels, Belgium, from September 24 to 27, 2003. There were more than 400 exhibitors and more than 25000 visitors. How many manufacturers know about the increase in visitors compared with 2001? More than 25% has been added. The exhibition fully demonstrates Europe's leading position in the diversity and flexibility of label and related product design. The 3-day "Labelexpo China 2003", the first China International label printing exhibition, came to a successful conclusion in Shanghai International Exhibition Center on January and February 11. Many international famous label manufacturers attended the label printing exhibition, such as Eli Denison AkzoNobel. HP—lndigo。 Prince paper rotoflex. Surface specialties, etc., provide domestic label manufacturers and professionals with the opportunity to see the latest products and technologies, and listen to the latest ideas and unique opinions of foreign peers. Ling3jing chemical, the label application, also tries to use the "onomatopoeia" inherent in Japanese to describe the expansion of the characteristic domain of materials. The successive large-scale investment of foreign famous manufacturers in China and the rise of some powerful private enterprises in China have refocused people's attention on this small label

at present, the label is not only a single carrier for recording commodity information and promoting commodities in people's impression, but also is developing in a multi-functional direction, especially in tobacco, alcohol and food. drugs. electronic product. In the field of goods identification and logistics, this trend is becoming more and more obvious. The market demand for multi-functional labels makes some label printing enterprises realize that only by constantly carrying out technological innovation and developing new products can they maintain their dominant position in the fierce competition

as an anti-counterfeiting label with independent or comprehensive functions, at present, it has developed into an independent category, ranging from the comprehensive anti-counterfeiting sticker visa with high safety to the waterproof warning and warranty label with single function, which requires a certain anti-counterfeiting function. This series of technical features of anti-counterfeiting labels have formed the general rules and mouth requirements for label design

the earliest anti-counterfeiting label in China appeared in the mid-1980s and was applied to wine and food. Medicine, health care products, cosmetics, computer software and hardware products, sports goods, automobile parts, agricultural materials and other fields. As an economic, practical and convenient means of anti-counterfeiting, anti-counterfeiting label has a broad space for development in China

the development and application of new anti-counterfeiting labels are based on the market demand and the development of related disciplines, involving physics. Chemistry. In high-tech fields such as optics, electronics, biology, and even atomic energy, the anti-counterfeiting efforts are also increasing. Gravure latent image label. Dripping disappearance label. Holographic hot stamping label. Thermochromic labels rely on the development of related materials and technologies. A German company has recently developed a new anti-counterfeiting label system, which uses a laser beam to inject data information into the label in the form of micron sized light spots, and identifies the authenticity of the product by identifying the hologram formed by the light spots. This system is the product of the combination of polymeric materials and holographic technology

for label application, it is necessary to prevent the label from being removed from one product and then pasted onto another product. To achieve the purpose of anti-counterfeiting, the label itself must have the corresponding anti-counterfeiting function, such as the anti-counterfeiting technology commonly used in Securities printing, such as watermark. Miniature text, fluorescent fiber, newsprint. Embossed latent image, etc. Using anti-counterfeiting inks such as photochromic inks and thermochromic inks can also make the printed images show different colors at different viewing angles or at different temperatures, so as to achieve the purpose of automatic analysis and processing of experimental results by anti-counterfeiting software; In addition, holographic images can be used for anti-counterfeiting on labels. Through the combination of two-dimensional and three-dimensional patterns, diffraction patterns or three-dimensional images, it is possible to diversify labels. For example, dynamic images and hidden marks have good anti-counterfeiting 1 wow. Machine readable labels can use extremely small nanoparticles invisible to human eyes, special transparent pigments or DNA markers (DNA identification), read unique information through special instruments, and identify the authenticity of products or certificates. The code anti-counterfeiting label can be queried by dialing the password or number to identify the authenticity of the product

the following is a brief introduction to the labels commonly used in the anti-counterfeiting field

1. anti uncovering label

the anti uncovering label is pasted on a certain base material and lifted after a certain period of time. The text hidden on the back of the label paper will be separated from the label surface material, leaving clear handwriting on the base material, so as to achieve the purpose of anti-counterfeiting and anti uncovering. The identification of this label does not require any instrument. Once the tool is lifted, the authenticity can be identified. It is non reusable, and whether it has been lifted can be effectively controlled through strong adhesive. The label surface can also be printed with different words according to customer requirements. Pattern, mark or bar code can also be added with anti-counterfeiting code. (to be continued)
