As a kind of pharmaceutical packaging material, aluminum foil is widely favored by users and pharmaceutical manufacturers in the market. In the early stage, aluminum foil bubble cover was only used as a form of packaging drugs. In the later stage, with the improvement of technology, aluminum foil bubble cover added many potential behaviors on the packaging, such as printing on the outer surface of aluminum foil, which played a role in drug description and promotion. The form of aluminum foil printing is also slowly more up. This format allows for extra space for marketing messages and high product identification value, while the foil can be printed on both sides.

Aluminum foil blister printing press printing forms can be divided into plain foil < no printing), printing foil (divided into single-sided printing, double-sided printing, monochrome printing, double color printing, multicolor printing), color foil (one gold, double gold, and green background, all sorts of color background), anti-counterfeiting printing (invisible text, pattern, positive and negative face seal). The surface printing of pharmaceutical foil has high technical requirements for the printing process. Pharmaceutical factories will carry out the outer packaging printing of aluminum foil according to the requirements of customers. Common printing uses width dimensions are generally 125 mm and 130 मिमी, 250 मिमी. 50 mm to 600 मिमी.

Although there are many forms of printing, the printing technology used for aluminum foil bubble cover packaging is relatively simple, and monochrome printing is common in the market. तथापि, this printing method has almost no anti-counterfeiting marks and special fake materials and means, which is easy to provide counterfeiters with convenient conditions for imitation and counterfeiting. Although it sounds very simple, it is difficult to achieve anti-counterfeiting printing in blister packaging. There are reports: in some western countries in order to anti-counterfeiting means, there will be nearly 10 kinds of anti-counterfeiting marks printed on a palm-sized drug box to ensure the safety of drugs. It uses microforms, glazing, and gravure printing techniques that can be seen with the naked eye as well as fake signs that can be seen with special lenses.

Some countries in order to be able to do on blister anti-counterfeiting, in pharmaceutical blister packaging surface, mostly adopted abroad laser holographic dark grain security inhibits PTP aluminum foil products, this way can make the laser holographic pattern has strong intuitive, and easy for consumers to identify, त्याच वेळी, will not affect the original print design and product packaging appearance. This anti-counterfeiting method is currently adopted by a number of multinational pharmaceutical groups, the application of invisible fluorescent anti-counterfeiting PTP aluminum foil material is also one of the development trends of drug packaging technology in the future. This anti-counterfeiting effect will be more hidden from the surface, it is difficult to observe with the naked eye, but when the UV lamp irradiation anti-counterfeiting signs or pattern text will be obvious, at present in China, some bubble packaging manufacturers have been applying this technology, but the total amount of use is relatively small compared with western developed countries.

सर्वसाधारणपणे बोलणे, Chinese pharmaceutical packaging enterprises still lag behind some developed countries in anti-counterfeiting technology, but with the improvement of people’s understanding of anti-counterfeiting technology and the importance of use, the level of anti-counterfeiting printing of Chinese pharmaceutical enterprises has been greatly improved. Many new anti-counterfeiting technologies are also being developed, such as digital anti-counterfeiting, ink anti-counterfeiting, special printing anti-counterfeiting, nuclear track anti-counterfeiting, biological anti-counterfeiting, and these are the general development direction of foil printing anti-counterfeiting in the future.
