In recent years, domestic and foreign anti-counterfeit labeling technology has made considerable progress, and has involved physics, chemistry, optics, electronics, biology, and even high-tech means such as the atomic energy sciences. As a result, its anti-counterfeiting efforts have continued to increase, and imitation has become increasingly difficult. Big, played a positive role in the anti-counterfeiting and anti-counterfeiting, standardizing the work of the market.
Basic requirements for anti-counterfeiting packaging
With the continuous development of the market economy, society has put forward new requirements for anti-counterfeit products and anti-counterfeiting technologies.
1. Ordinary consumers are apt to recognize that due to the adoption of various high-tech and difficult technologies, the difficulty of imitation has been increased, but the difficulty of recognition has been correspondingly increased. It is often necessary to use specialized instruments or equipment for identification, or to have professional knowledge. Recognition, this poses a difficulty for counterfeiting of commodities. For those ordinary consumers who buy 1 bag of detergent and 1 pack of MSG, it is impossible to ask an expert to help him identify the authenticity of the product or the authenticity of the anti-counterfeit tag itself, let alone use a special test instrument to identify the authenticity of the product. . Therefore, it is necessary to develop and produce an anti-counterfeit label that is easily recognizable by consumers and is not easily copied. To meet the security needs of commodities.
2. Satisfy hygienic conditions and mass production requirements
At present, a large number of commodity labels in China still use manual labeling methods. This is a difficult requirement for products with higher hygiene standards (medical and health products, foods, etc.), and manual labeling is difficult to meet hygiene standards. With the development of production and the improvement of consumer demand for product quality, automatic labeling for accurate positioning is imminent.
The new type of anti-counterfeiting compound packaging material produced by the film labeling technology to be introduced in this paper basically solves the above problems, and is easy to identify and difficult to copy.
Automatic labeling and compounding process
The new anti-counterfeiting compound packaging material produced by automatic film labeling technology is formed by using high-tech work tools and equipment to attach security labels in the sandwich of traditional composite packaging materials, and has a special anti-counterfeiting effect. The production process is: prior to the composite process of packaging materials, using high-speed automatic labeling technology, the anti-counterfeiting labels are attached to the surface of the bottom film or the back surface of the pellicle, and then compounded so that the anti-counterfeiting labels are naturally stuck between the two layers of composite materials. Composite packaging materials blend into one.
Because the new anti-counterfeit composite packaging material manufactured by the automatic film labeling technology integrates the anti-counterfeiting label in the middle of two layers of materials, the label can neither be transferred nor worn, and more importantly, it is easy to identify. Authenticity is true, and affixed to the inner and outer surfaces is false, and compounding is true in the middle of the material. Even if it is blind, it can be recognized immediately. This makes it very easy to identify the authenticity of goods, and the production of such anti-counterfeiting packaging materials requires a series of high-tech means and is not easily copied. In addition, the label can also be accurately and precisely attached to the designated position of the composite package, so that the anti-counterfeit label is integrated with the package, which increases the aesthetic appearance of the package, and the added cost is very limited.
The use of film labeling technology to manufacture composite packaging materials requires the following elements.
Labels can be made using a variety of high-tech means, such as holographic anti-counterfeiting labels, paper stickers, plastic stickers, etc., but must contain adhesive layers, and must be disc-shaped labels, that is, through specific Production process and technology, rewind the label into a plate.
2. Labeling surface
The labeling surface may be a plastic film (including the inner layer of the composite film), paper, a metal film, and any planar material that can be combined with a transparent material, as long as it is an item requiring security or its packaging.
3. Non-labeled film
The non-labeled film may be a commercially available transparent film, or may be a polymer transparent film produced at the time of compounding.
4. Targeting labeling
The use of a disc-shaped tag in combination with a fully automatic positioning and labelling device enables the tag to be pasted in a designated location requiring security without manual intervention.
The application of accurate positioning and labeling technology enables all types of anti-counterfeiting functions to be completed in the production process of the protected product (production line) and in the specific production stage of the protected product (in the production of packaging and key components). The implementation can be combined with the printing and packaging production lines to form an anti-counterfeit effect that cannot be achieved manually.
In the packaging design, a special transparent window can be left on the pellicle of the composite film so that the anti-counterfeit label attached under the film can be seen. The exact position within the window can also be used as a basis for authenticating the false and Counterfeiters can't use manual methods to paste the label into the correct orientation. If the anti-counterfeit label uses aluminum-plated holographic anti-counterfeiting labels, then the bottom film is made of aluminum-plated film or aluminum paper, and the label and package are integrated into one body, which is more beautiful; after various anti-counterfeiting labels are also attached under the mask, Then add a background color, so that the security label and packaging integration, appearance is also very good.
The laminated and non-labeled layers that have been positioned and labelled are completely traditional and do not require any changes.
Film labeling compound anti-counterfeiting technology is a set of product security. Anti-counterfeiting technology and process security in one comprehensive anti-counterfeiting technology. In addition to all the features of general label anti-counterfeiting, the use of film-based labeling and composite anti-counterfeit packaging materials will make it impossible for the anti-counterfeiting technology of the protected object to be realized after it is separated from the original system anti-counterfeiting equipment and technology anti-counterfeiting technology. Only this technology is available. Equipment and equipment can achieve the same anti-counterfeiting function. In addition, this anti-counterfeiting technology is independent of anti-counterfeit labels, and is not limited by the type of labels. Users have a wide range of choices for anti-counterfeiting labels. This kind of anti-counterfeiting technology has strong specificity and can be closely combined with the user's production process, and the overall anti-counterfeiting capability is very strong. Sub-film labeling of composite anti-counterfeiting packaging materials enhances the anti-counterfeiting function of the anti-counterfeiting label itself, so the anti-counterfeiting technology adopted by the label itself can be reduced accordingly, that is, the packaging cost is also reduced. This new type of anti-counterfeit packaging products is found in China's salt industry, pharmaceutical industry and food industry. Fertilizer industry has been widely used, and has achieved good social and economic benefits.
To produce high-speed mass-produced anti-counterfeit composite packaging materials, it must be possible to use professional processes and equipment.
1. basic requirements
1) High-speed, high-precision automatic labeling system
The automatic labeling system requires a labeling speed of 500-600 pieces/minute or more to be able to match other printing equipment and is compatible with the demand for bulk materials for packaging materials.
2) High accuracy of labeling position
The labeling accuracy is generally within Â±1mm. The requirement of high precision is of great significance, which not only increases the aesthetics of the packaging, but more importantly, the accurate positioning itself is a kind of anti-counterfeiting means. Manual labeling cannot achieve mass production.
3) Compatible with printing equipment and materials
In order to be compatible with printing equipment and materials, the labeling machine has to be small in size. Because many packages are small in size, it is possible to print multiple packaging units side by side on the width of the film, such as one out of four, one out of five, or even out of seven. Or eight, often need more than one labeling machine.
4) With multiple linkage functions
The automatic labeling system is required to have a plurality of linkage functions, otherwise it is impossible to attach a plurality of anti-counterfeiting labels at the same time at the same time, which will affect the production efficiency and reduce the yield.
2. Institutional composition
Film under the automatic labeling system can be used with the printing press, rewinding machine, complex machine. To produce composite anti-counterfeiting packaging materials, in addition to automatic labeling systems that require high technical content, disc labels that match high-speed labeling systems must also be provided, because fully automatic labeling machines mostly use roll-shaped disc labels to adapt In high-speed automatic pasting, there is a higher requirement for the labelling bottom paper material and the quality of the labeling and cutting. Otherwise, failures such as breakage tapes and missing stickers can be easily formed on the automatic labeling system, which will seriously affect the production efficiency and reduce the yield. , increase production costs.
From the above analysis, it can be seen that the core technology and process equipment for realizing the labeling under the film and making a new type of anti-counterfeit composite material are the high-speed automatic labeling technology and the automatic labeling system. The automatic labeling system can automatically position and label in the printing process of the composite film, in the rewinding inspection process after the printing, or in the compounding process, and thus is easy to produce with the existing composite packaging or composite packaging material. Supporting the enterprise to form a new type of anti-counterfeiting packaging material, so that the product of composite packaging materials rise to a new height and improve the anti-counterfeiting function of composite packaging materials.
