Development and application of anti fake packaging

Research, development and application of material anti-counterfeiting packaging technology

at present, anti-counterfeiting technology is widely used, especially the emergence of new materials and new processes, which has promoted the development and application of material anti-counterfeiting technology, and many new anti-counterfeiting materials have emerged

the so-called material anti-counterfeiting is to achieve the purpose of anti-counterfeiting by using the characteristics of the product's own materials or the internal and external packaging materials of the product, which are difficult to imitate or cannot imitate products with good quality. Common anti-counterfeiting materials mainly refer to the latter, such as all kinds of anti-counterfeiting paper, anti-counterfeiting film, anti-counterfeiting tape, etc. have been widely used in the packaging and printing of commodities

anti counterfeiting paper

paper anti-counterfeiting materials account for a large proportion in the field of anti-counterfeiting. They are mostly used in the anti-counterfeiting of banknotes, securities, certificates and commodity marks, and have been developed to be directly applied to the internal and external packaging of products. Its anti-counterfeiting function can be achieved by printing anti-counterfeiting marks on the paper, adding special materials in the process of paper making, or processing the package after finishing the packaging, such as stamping anti-counterfeiting marks on the paper. The following mainly introduces the anti-counterfeiting paper technology from the perspective of adding special ingredients in the paper manufacturing process or processing through special processes, so that the paper itself has the anti-counterfeiting function

anti counterfeiting paper is mainly divided into three categories. One category is mainly used for banknotes, various securities, stocks and bills with circulation performance or long-term preservation; The first category is mainly used for important certificates, general certificates, etc; The third category is used for anti-counterfeiting printing of product specifications, trademarks and commodity packaging

the biggest feature of anti-counterfeiting paper is that it is anti-counterfeiting before printing or packaging, that is, the paper has the corresponding anti-counterfeiting function at the time of forming; Secondly, it is easy to identify; The third is the powerful anti-counterfeiting function. Due to the corresponding regulatory restrictions on the development and production of anti-counterfeiting paper, the security of anti-counterfeiting paper is also protected. In addition, the anti-counterfeiting function should be added to the product packaging or trademark. The use of anti-counterfeiting paper is a method with the best effect and the lowest cost in the anti-counterfeiting technology. Therefore, at present, the application field of anti-counterfeiting paper is expanding, and the amount of anti-counterfeiting paper in packaging and commodity identification has gradually exceeded that of banknote paper. The anti-counterfeiting paper used now mainly includes the following categories

first 1 Laser holographic anti-counterfeiting paper

Special broaching machine for impact sample notch is used to process samples for experiments. The laser holographic anti-counterfeiting paper directly prints or transfers the pictures and texts of the experimental machine specialized in Jinan new era Gold Testing Instrument Co., Ltd. after laser photography and plate making to the paper. The laser holographic anti-counterfeiting paper has the following advantages:

1) it makes the holographic image directly on the paper, removing the thin-film information layer, Therefore, the possibility of being copied is reduced

2) the patterns on the anti-counterfeiting paper can be designed and made according to the requirements of the business, and the anti-counterfeiting coated paper, paperboard, paperboard, etc. with different textures and different quantities (70 ~ 400g/m2) required by users can be produced, and all kinds of printing can be carried out like ordinary paper

3) the price of laser holographic anti-counterfeiting paper is only slightly higher than that of ordinary composite gold and silver card paper, which is equivalent to one tenth of the price of holographic anti-counterfeiting trademark, and saves the labeling fee, which is easy to be accepted by merchants

4) directly using laser anti-counterfeiting paper for packaging and printing can not only play an overall anti-counterfeiting role, but also be very beautiful and have a good decorative effect

5) because holographic paper gets rid of polymer materials that are difficult to degrade, it can be weathered in the soil after being discarded and will not cause environmental pollution. Therefore, it will gradually replace laser holographic products containing plastic film

because it has the remarkable characteristics of overall anti-counterfeiting, some cigarettes, alcohol, cosmetics, food, medicine, health products, etc. have begun to use laser holographic anti-counterfeiting paper for packaging, and have achieved good economic benefits. In addition, the anti-counterfeiting paper can also be used in the decoration and anti-counterfeiting of high-end handicrafts, anti-counterfeiting certificates, stamps, greeting cards, etc. Especially in the anti-counterfeiting of cigarette packs, taking laser holographic anti-counterfeiting paper as the packaging material of cigarette packs can achieve a balance in anti-counterfeiting performance and price. Many cigarette factories have adopted this anti-counterfeiting technology

2. Laser (laser) hot stamping materials

laser hot stamping materials are holographic images made on hot stamping paper or film, which can be transferred to the surface of the substrate by heating. This anti-counterfeiting material has considerable application prospects and has been adopted by many well-known domestic manufacturers, such as the packaging of many cigarette boxes, toothpaste and other products. Laser (laser) bronzing paper is divided into two categories: hot plastic and hot paper glue. It has multiple price levels and adapts to different customer groups. Hot stamping paper is suitable for hot stamping logo patterns, invitations, greeting cards, covers, etc. Hot plastic is suitable for hot stamping all kinds of molded objects, such as pen holders, plastic toys, etc. it can also be hot printed on PET film, and then coated with back glue and pasted on various products as advertisements or trademarks, so that the products have a luxurious and high-end feeling. The above laser products can be made into special editions according to the specific requirements of customers

3. Watermark paper

watermark is to use a printing roller engraved with watermark pattern by bronze to press on the wet paper page in the process of papermaking, so that the imprinted parts crowd out some fibers to form a watermark pattern composed of fibers with different densities. These patterns are usually difficult to see, and can only be seen against strong light. The main reason is that after the paper is finished, due to the different density of the pulp at the image and text, its transmittance is different. Therefore, when observing the light transmission, the original designed image and text can be displayed. These images and text are called watermarks. Most of the large denominations of RMB issued in China are printed on watermark paper. Today, with the development of science and technology, watermark is still recognized as an effective anti-counterfeiting technology by anti-counterfeiting experts all over the world, and continues to be adopted and developed by all countries

there are three kinds of watermarks: fixed watermark, semi fixed watermark and unfixed watermark

the fixed watermark must be fixed on a certain position of the main body of banknotes, passports, certificates, etc., and it usually needs to be accurate relative to the printed graphics and texts or other anti-counterfeiting measures visible to the naked eye. Fixed watermark requires the whole paper to present a watermark pattern. The position of the watermark pattern is fixed, and its specific position can be determined by the user, so that users can identify their products according to the watermark pattern and position. The watermark can also be made into black and white. The black watermark pattern is darker than other parts of the paper; The white watermark pattern is lighter than other parts of the paper

semi fixed watermark is that the distance and position between each group of watermarks are fixed, and each group is arranged continuously on the paper, so it is also called continuous watermark, which is mostly used for special paper

unfixed watermarks are distributed on the full page of paper or face, so they are also called full page watermarks. The whole paper presents a watermark pattern. There is no strict requirement on the position of the watermark pattern. The pattern can be made according to the user's requirements. The watermark pattern is visible in the light, and it is also divided into black and white. Some countries' passports use line watermarks, such as the maple leaf fixed watermarks on the pages of Canadian passports. It is reported that a transparent watermark has been developed abroad, which can only be displayed and recognized from a certain angle
