Analysis of automatic labeling equipment and composite anti-counterfeiting packaging materials

in recent years, anti-counterfeiting label technology at home and abroad has made great progress, and has involved high-tech means such as physics, chemistry, optics, electronics and biology, and even atomic energy, which has continuously strengthened its anti-counterfeiting efforts and increased the difficulty of imitation, and has played a positive role in the work of anti-counterfeiting and anti-counterfeiting and standardizing the market. Basic requirements of anti-counterfeiting packaging

with the continuous development of market economy, society has put forward new requirements for anti-counterfeiting products and anti-counterfeiting technology

1. Ordinary consumers are easy to identify

due to the use of various high-tech and difficult technologies, it is more difficult to copy, but the identification difficulty is also relatively detailed. The verification results will be published at the SAE World Conference held in Detroit from April 21 to 23, which should be improved. It often needs special instruments or equipment to identify, or people with professional knowledge to identify, which poses difficulties for the anti-counterfeiting of bulk commodities. For those ordinary consumers who buy a bag of washing powder and a bag of monosodium glutamate, it is impossible to ask experts to help them identify the authenticity of the goods or the authenticity of the anti-counterfeiting label itself, let alone use special testing instruments to identify the authenticity of the products. Therefore, we must develop and produce an anti-counterfeiting label that is easy for consumers to identify but not easy to copy, in order to meet the anti-counterfeiting needs of bulk commodities

2. Meet the requirements of sanitary conditions and large-scale production

at present, a large number of commodity labels in China still use manual labeling, which is difficult to meet the hygienic standards for some products with high hygienic standards (medical and health products, food, etc.). With the development of production and the improvement of consumers' requirements for commodity quality, it is urgent to realize automatic labeling with accurate positioning

the new anti-counterfeiting composite packaging material produced by under film labeling technology introduced in this paper basically solves the above problems, and is easy to identify and not easy to copy

automatic labeling and composite technology

the new anti-counterfeiting composite packaging material produced by using automatic under film labeling technology is formed by using high-tech technology and equipment to affix anti-counterfeiting labels in the interlayer of traditional composite packaging materials, which has its special anti-counterfeiting effect. The manufacturing process is: before the packaging material composite process, the anti-counterfeiting label is pasted on the surface of the bottom film or the reverse side of the surface film by using the high-speed automatic labeling technology, and then compounded, so that the anti-counterfeiting label is naturally pasted between the two layers of composite materials and integrated with the composite packaging materials

because the new anti-counterfeiting composite packaging material manufactured by the automatic under film labeling technology is to compound the anti-counterfeiting label between two layers of materials, the label can neither be transferred nor worn. More importantly, it is easy to identify. As long as you touch it with your hand, you can know the authenticity. What is pasted on the inner and outer surfaces is fake, and what is compounded in the middle of the material is true. Even blind people can be identified by touching them. This makes it very easy to identify the authenticity of goods, and the production of this anti-counterfeiting packaging material requires a series of high-tech means, which is not easy to copy. In addition, the label can also be accurately affixed to the designated position of the composite packaging, so that the anti-counterfeiting label is integrated with the packaging, which increases the beauty of the packaging, and the added cost is very limited

the following elements are required for manufacturing composite packaging materials using under film labeling technology

1. Labels

labels made by various high-tech means can be used, such as holographic anti-counterfeiting labels, paper self-adhesive labels, plastic self-adhesive labels, etc., but they must contain an adhesive layer and must be disc-shaped labels, that is, the labels are rewound into discs through specific production processes and technologies

2. Labeling surface

the labeling surface can be plastic film (including the inner layer of composite film), paper, metal film and any plane material that can be compounded with transparent materials, as long as it is an article that needs anti-counterfeiting or its packaging

3. Non labeled film

non labeled film can be either a commercially available transparent film or a composite 7. Large deformation indication error: polymer transparent film generated when the indication is within ± 1%

4. Positioning label

use the disc label together with the full-automatic positioning and labeling equipment, and the label can be pasted at the designated position requiring anti-counterfeiting through non manual intervention

the application of accurate positioning and labeling technology enables all kinds of anti-counterfeiting functions to be completed not only in the production process of protected products (production line), but also in the specific production stage of protected products (in the production of packaging materials and key components). It can be combined with printing and packaging production lines to form an anti-counterfeiting effect that cannot be achieved manually

in the packaging design, a specific transparent window can be left on the surface film of the composite film, so that the anti-counterfeiting label pasted under the film can be seen easily, and its accurate position in the window can also be used as a basis for identifying the true and false, because the counterfeiter cannot paste the label to the accurate orientation by manual method. If the anti-counterfeiting label adopts aluminized holographic anti-counterfeiting label, the bottom film adopts aluminized film or aluminum paper to compound, and the label and the package are integrated into one, which is more beautiful; You can also paste various anti-counterfeiting labels under the facial mask, and then print a background color to integrate the anti-counterfeiting labels with the packaging, and the appearance effect is also very good

5. Composite

the pasted surface after positioning and labeling will be combined with the non labeling layer. This process is completely a traditional process and does not need to make any changes

under film labeling composite anti-counterfeiting technology is a comprehensive anti-counterfeiting technology integrating product anti-counterfeiting, process anti-counterfeiting and process anti-counterfeiting. In addition to having all the characteristics of general label anti-counterfeiting, the anti-counterfeiting technology of the protected object can no longer be realized after it is separated from the original system anti-counterfeiting equipment and process anti-counterfeiting technology by using the composite anti-counterfeiting packaging material under the film. Only with this set of process technology, equipment (equipment) can the same anti-counterfeiting function be realized. In addition, this anti-counterfeiting technology is independent of anti-counterfeiting labels and is not limited by the types of labels. Users have a very wide range of options for anti-counterfeiting labels. This kind of anti-counterfeiting technology has strong specificity, and can be closely combined with the user's production process, with strong overall anti-counterfeiting ability. The composite anti-counterfeiting packaging with under film labeling can also improve the transparency. The material improves the anti-counterfeiting function of the anti-counterfeiting label itself, so the anti-counterfeiting technology adopted by the label itself can be reduced correspondingly, that is, the packaging cost will also be reduced. This new anti-counterfeiting package has been widely used in China's salt industry, pharmaceutical industry, food industry, chemical fertilizer industry, and has achieved good social and economic benefits

automatic labeling composite equipment

in order to produce anti-counterfeiting composite packaging materials in large quantities at high speed, professional technology and equipment must be adopted

1. Basic requirements

1) high speed and high precision automatic labeling system

the automatic labeling system requires a labeling speed of more than 500 ~ 600 pieces/minute to match with other printing equipment and the demand of bulk commodities for packaging materials

2) high accuracy of labeling position

generally, the labeling accuracy should be within ± 1mm. Requiring high precision is of great significance, which not only increases the beauty of the packaging, but also accurately determines that the friction surface should be absolutely clean. The clean position itself is a means of anti-counterfeiting, and manual labeling cannot achieve mass production

3) matching with printing equipment and materials

in order to match with printing equipment and materials, the labeling machine should be small in size. Because many packages are small in size, there may be multiple packaging units printed side by side on the width of the film, such as one out of four, one out of five, or even one out of seven or eight, which often requires multiple labeling machines

4) it has multiple linkage functions

the automatic labeling system is required to have multiple linkage functions, otherwise it is impossible to stick multiple anti-counterfeiting labels side by side at the same time, which will affect the production efficiency and reduce the yield

2. Mechanism composition

the fully automatic labeling system under the film can be used together with the printing machine, rewinder and laminating machine. Figure 3 and Figure 4 show the full-automatic labeling and rewinding system with industrial computer for making anti-counterfeiting composite packaging materials

manufacturing technology of disc label tape

the production of composite anti-counterfeiting packaging materials requires not only a full-automatic labeling system with high technical content, but also a disc label matching the high-speed labeling system, because most of the full-automatic labeling machines use coiled disc labels. In order to adapt to high-speed automatic pasting, there are high requirements for label tape backing materials, label die-cutting quality, etc., otherwise it is very easy to form broken tapes on the automatic labeling system Failures such as missing stickers seriously affect the production efficiency, reduce the yield and increase the production cost

from the above analysis, it can be seen that the core technology and process equipment for realizing under film labeling and making new anti-counterfeiting composite materials are high-speed fully automatic labeling technology and automatic labeling system. This automatic labeling system can realize automatic positioning and labeling in the printing process of composite film, the rewinding inspection process after printing, or in the composite process. Therefore, it is easy to match with the existing composite packaging materials or composite packaging material production enterprises to form the ability to make new anti-counterfeiting packaging materials, so as to raise the products of composite packaging materials to a new height and improve the anti-counterfeiting function of composite packaging materials
