Basic requirements for anti-counterfeiting packaging In the context of the continuous development of the market economy, the society has put forward new requirements for anti-counterfeiting products and anti-counterfeiting technology.
1. Easy to identify by ordinary consumers Due to the use of various high-tech and difficult technologies, the difficulty of imitation is increased, but the difficulty of recognition is also improved. It is often identified by special instruments or equipment, or has expertise. People can identify, which makes the security of bulk commodities difficult. For those ordinary consumers who buy 1 bag of detergent and 1 packet of MSG, it is impossible for experts to help him identify the authenticity of the goods or the authenticity of the anti-counterfeit label itself, let alone use special test equipment to identify the authenticity of the product. . Therefore, it is necessary to develop and produce an anti-counterfeit label that is easy for the consumers to identify and not easy to imitate, in order to meet the anti-counterfeiting needs of commodities.
2. Meeting the requirements of sanitary conditions and large-scale production At present, a large number of commodity labels in China still use manual labeling methods. For some products with high hygiene standards (medical hygiene products, foods, etc.), manual labeling is difficult to achieve hygiene. standard. With the development of production and the advancement of consumer demand for quality of goods, automatic labeling to achieve correct positioning is imminent.
The new anti-counterfeit composite packaging material produced by the sub-film labeling technology introduced in this paper basically solves the above problems, and is easy to identify and difficult to imitate.
Automatic labeling and compounding process The new anti-counterfeiting composite packaging material produced by automatic sub-film labeling technology is formed by applying high-tech technology and equipment to the anti-counterfeit label of the traditional composite packaging material. It has special anti-counterfeiting. effect. The manufacturing process is: before the packaging material composite process, using the high-speed automatic labeling technology, the anti-counterfeit label is attached to the surface of the film or the reverse side of the film, and then composited, so that the anti-counterfeit label is naturally adhered between the two layers of composite materials, and Composite packaging materials are integrated.
Since the new anti-counterfeiting composite packaging material manufactured by the automatic sub-film labeling technology is to composite the anti-counterfeiting label between the two layers of materials, the label can neither be transferred nor worn, and more importantly, it is easy to identify, as long as it is touched by hand. Knowing the truth, it is false on the inner and outer surfaces, and it is true in the middle of the material. Even blind people can recognize it. This makes the authenticity identification of goods very easy, and the production of such anti-counterfeiting packaging materials requires a series of high-tech means, which is not easy to imitate. In addition, the label can be accurately attached to the specified position of the composite package, so that the anti-counterfeit label and the package are integrated, which increases the appearance of the package, and the added cost is very limited.
The following elements are required to manufacture composite packaging materials using sub-film labeling technology.
1. Labels can be made of labels made by various high-tech means, such as holographic security labels, paper stickers, plastic stickers, etc., but with an adhesive layer, and must be a disc-shaped label, ie The label is re-rolled into a tray by a specific production process and technology.
2. The labeling surface can be a plastic film (including the inner layer of the composite film), paper, metal film and any flat material that can be combined with the transparent material, as long as it is an anti-counterfeiting item or its packaging. .
3. The non-labeling film non-labeling film may be a commercially available transparent film or a polymer transparent film which is inherently compounded.
4. Positioning labeling The disc label is used in conjunction with the fully automatic positioning labeling equipment, and the label can be pasted in a designated position requiring anti-counterfeiting by means of non-manual intervention.
Correct positioning of the application of labeling technology, so that all kinds of anti-counterfeiting functions can be completed in the production process of the protected product (on the production line), and in the specific production stage of the protected product (in the production of packaging materials and key components) The implementation can be combined with the 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 of the composite film so as to be able to see the anti-counterfeit label attached to the film, and its correct position in the window can also be used as a basis for authenticating the true and false. The counterfeiter cannot manually paste the label into the correct orientation. If the anti-counterfeit label adopts the aluminized holographic anti-counterfeit label, then the base film is composited by aluminized film or aluminum paper, and the label and the package are integrated into one body, which is more beautiful; and after the various anti-counterfeit labels are attached under the mask, Add a base color to make the security label and the package together, and the appearance is also very good.
5. The composite will be laminated with the non-labeled layer after the positioning and labeling. This process is completely a traditional process and does not need to be changed.
The under-film labeling compound anti-counterfeiting technology is a comprehensive anti-counterfeiting technology that integrates product anti-counterfeiting, process anti-counterfeiting and process anti-counterfeiting. In addition to all the characteristics of general label anti-counterfeiting, the use of under-film labeling composite anti-counterfeiting packaging materials, so that the anti-counterfeiting technology of the protected object can not be realized after leaving the original system anti-counterfeiting equipment and technology anti-counterfeiting technology, only have this set of technology Equipment (equipment) can achieve the same anti-counterfeiting function. In addition, this anti-counterfeiting technology is independent of the anti-counterfeit label and is not limited by the type of label. The user has a very wide selectivity for the anti-counterfeit label. This kind of anti-counterfeiting technology has strong specificity and can be closely integrated with the user's production process, and the overall anti-counterfeiting ability is very strong. The under-film labeling composite anti-counterfeiting packaging material enhances the anti-counterfeiting function of the anti-counterfeit label itself, so the anti-counterfeiting technology adopted by the label itself can be correspondingly reduced, that is, the packaging cost is also reduced. This new type of anti-counterfeit packaging has been widely used in China's salt industry, pharmaceutical industry, food industry, fertilizer industry, etc., and has achieved good social and economic benefits.
Automatic labeling and compounding equipment is required to produce anti-counterfeiting composite packaging materials at high speed and in large quantities, which must be realized by professional techniques and equipment.
1. Basic requirements 1) High-speed, high-precision automatic labeling system The automatic labeling system requires a labeling speed of 500 to 600 pieces per minute or more to match other printing equipment, and the demand for packaging materials for bulk commodities. adapt.
2) Labeling position accuracy High labeling accuracy is generally within ±1mm. The requirement for high precision is significant, which not only increases the aesthetics of the package, but more importantly, correct positioning itself is an anti-counterfeiting method, which cannot be mass-produced by manual labeling.
3) Matching with printing equipment and materials In order to match the printing equipment and materials, the labeling machine has a small volume. Since many packages are small in size, a plurality of packaging units may be printed side by side on the width of the film, such as one out of four. One out of five, or even seven or eight, often requires multiple labeling machines.
4) Having multiple linkage functions requires the automatic labeling system to have multiple linkage functions. Otherwise, it is impossible to simultaneously affix multiple anti-counterfeit labels side by side, which will affect production efficiency and reduce the yield.
2. Institutional composition The automatic labeling system under the film can be used together with the printing machine, the winder and the compound machine. Figure 3 and Figure 4 show the automatic labeling and rewinding system for manufacturing anti-counterfeiting composite packaging materials with industrial computer.
The disc-shaped label manufacturing technology produces composite anti-counterfeiting packaging materials. In addition to the automatic labeling system with high technical content, it also needs to provide disc-shaped labels that match the high-speed labeling system, since the automatic labeling machines mostly use rolls. The disc-shaped label has high requirements for high-speed automatic paste, and the quality of the label bottom paper material and the label die-cutting quality. Otherwise, it is easy to form faults such as broken belts and missing stickers on the automatic labeling system, which seriously affects Production efficiency, reduced yield, and increased production costs.
It can be seen from the above analysis that the core technology and process equipment for achieving sub-film labeling and manufacturing of new anti-counterfeiting composite materials are high-speed automatic labeling technology and automatic labeling system. The automatic labeling system can realize the automatic positioning and labeling in the printing process of the composite film, the rewinding inspection process after printing, or the composite process, so that it is easy to produce with the existing composite packaging or composite packaging materials. The company's supporting ability to form a new type of anti-counterfeiting packaging materials will raise the product of composite packaging materials to a new height and improve the anti-counterfeiting function of composite packaging materials.
Analysis of automatic labeling equipment and composite anti-counterfeiting packaging materials
