The aluminum foil used in drug blister Packaging is the sealing material sealed on the plastic hard sheet, also known as the capping material, usually called پی ٹی پی فارماسیوٹیکل ایلومینیم ورق, which comes from the abbreviation of Press Through Packaging in English, meaning “Packaging by pressure”, Through a pressure means to seal the operation. PTP aluminum Foil is a word widely used in Asia. یورپ میں, people commonly use the expression push-through Foil, which means “push-through aluminum Foil” in Chinese. But the abbreviation PTP seems to be more commonly used. This is also the reason why drug blister packaging is called PTP aluminum foil.

This push-in packaging ensures product or packages integrity in unit dose blister packaging compared to other packaging methods, as each drug product can be individually packaged, including shelf life for each individual dose. اس طرح سے, the drug is placed in the pit (bubble cover or blister eye) of the plastic hard sheet formed by blister, and then a piece of aluminum foil, which is printed by gravure and coated with a protective agent and adhesive, is bonded with the plastic hard sheet and sealed by heat so that the drug is sealed to the maximum extent and the drug is guaranteed to be intact.

Drug blister packaging was first developed by European countries in the 1930s. After gradual improvement and promotion, this method was recognized by more people and soon became popular. The application of this kind of packaging in China is relatively late, and the bubble cover packaging used in the early 1970s is mostly imported with the help of foreign regions. Later, with the increase of international exchanges, In the early 1980s, China successively introduced foreign pharmaceutical “پی ٹی پی” aluminum foil printing and coating equipment and technology from Guangzhou, Lianyungang, and other areas. In the 1990s, with the development and progress of technology, China has been able to produce monochrome or multi-color aluminum foil printing and coating equipment and can print gold series of drug packaging aluminum products.

This good medicinal “پی ٹی پی” aluminum foil is non-toxic and tasteless as sealing material. The raw material is mainly made of 8011-H18 or 8011-O aluminum foil. The required thickness is between 0.016 اور 0.04 ملی میٹر. The material used for processing and production is 99% electrolytic aluminum with a series of calendering and other processing means. Can have excellent electrical conductivity and shading, as well as high moisture resistance, gas resistance. عام طور پر استعمال شدہ ایلومینیم فوائل چھالا, the material requirements are very strict, requiring a thickness of 0.02mm, tensile strength of 98kPa, rupture strength of 90kPa, to make the surface clean, ہموار, کوئی جھریاں نہیں, کوئی انڈینٹیشن نقصان نہیں, no pieces of fluorescent material, in this respect, Henan Huawei Aluminum has been striving for perfection, the pursuit of better.

With the development of the pharmaceutical industry in the later stage and the improvement of the technical level, people and enterprises will have higher and higher requirements on the quality of pharmaceutical foil, such as the increase of printing color, finer surface quality requirements, and the improvement of the speed of gluing and coloring equipment.
