Drug packaging materials for drug packaging

by admin

pharmaceutical packaging materials refer to the materials used to manufacture packaging containers, packaging decoration, packaging printing, packaging and transportation to meet the packaging requirements of products. They include metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fiber, chemical fiber, composite materials and other main packaging materials, as well as coatings, adhesives, binding belts, decoration, printing materials and other auxiliary materials
classification of packaging materials: packaging tape, packaging tape, plastic packaging tape, plastic packaging tape, winding film, PE winding film, PE stretching film and other packaging materials. 1. Packaging materials with certain mechanical properties should be able to effectively protect products, so they should have certain strength, toughness and elasticity to adapt to the influence of static and dynamic factors such as pressure, impact and vibration
2. According to the different requirements for product packaging, the packaging materials should have a certain barrier to moisture, steam, gas, light, aromatic aroma, peculiar smell, heat, etc
3. With good safety performance, the toxicity of packaging materials should be small to avoid polluting products and affecting human health; The packaging materials shall be non corrosive and have the properties of insect proof, moth proof, rat proof and microbial inhibition, so as to protect the product safety
4. With proper processing performance, the packaging materials should be suitable for processing and easy to be made into various packaging containers. It should be easy for the mechanization and automation of packaging operations to adapt to large-scale industrial production. It should be suitable for printing and easy to print packaging marks
5. Packaging materials with good economic performance should have wide sources, convenient materials and low cost. After use, the packaging materials and packaging containers should be easy to handle without polluting the environment and causing public hazards. Class I drug packaging materials refer to the materials and containers for drug packaging that are in direct contact with drugs and used directly
class II drug packaging materials refer to the materials and containers for drug packaging that are in direct contact with drugs but easy to clean. In the process of actual use, they need to be cleaned and can be disinfected and sterilized
class III drug packaging materials refer to other drug packaging materials and containers other than class I and II that may directly affect the quality of drugs
the classified catalogue of drug packaging materials shall be formulated and published by the State Drug Administration. Pharmaceutical packaging machinery is a branch of general packaging machinery with high technical content and requirements. Since pharmaceutical equipment is an important part of GMP hardware, since China launched the GMP compulsory certification system, local pharmaceutical factories have accelerated the pace of technological transformation. The substantial renewal of production equipment has brought a favorable situation to the upstream industry of the pharmaceutical industry, the pharmaceutical machinery industry, and a large number of production line transformation has brought a huge market to pharmaceutical machinery enterprises. For example, the ampoule (water needle) series washing, drying, filling and sealing linkage unit introduced and developed by Changsha Zheng traditional Chinese medicine machine factory has ended the single machine production history of decades in China. After several improvements, the product has sold more than 600 production lines and exported to nearly 20 countries such as Brazil, Russia, Pakistan and Iran
of course, on the whole, the R & D of most packaging machines with advanced data technology in China is still in the imitation class, and the ability of independent development is still very limited. To this end, many large foreign enterprises have introduced their own technologies and components into China and processed them locally, thus reducing costs and fierce competition with local products
according to data, as early as 2003, the global drug packaging market reached US $11.2 billion, with an average annual growth of nearly 5%. It is estimated that it has exceeded US $13 billion in 2006. The United States, Japan, Britain, Germany, France and Italy account for the largest market share of the world’s pharmaceutical packaging industry, while China is the fastest-growing country. According to the development speed of China’s pharmaceutical industry, the annual GDP of pharmaceutical packaging materials will quickly exceed 20 billion yuan in the short term
the annual output value of China’s pharmaceutical packaging industry is about 15 billion yuan, with an annual growth rate of more than 10%. However, it can only meet about 80% of the needs of domestic pharmaceutical enterprises, and the contribution rate of packaging materials to the pharmaceutical industry is also low. In developed countries, packaging accounts for 30% of the value of drugs, while in China, this figure is less than 10%. In order to meet the needs of the rapid development of the pharmaceutical industry and actively participate in international competition, China’s packaging machinery must break the industry trend of “small and scattered” and continue to move forward in the direction of “high precision”. Industry insiders believe that in the future, the packaging industry will cooperate with the trend of industrial automation and develop in the direction of diversified mechanical functions, standardized and modular structural design, intelligent control and high-precision structure
the packaging chain is highly automated. Most of the packaging work of domestic pharmaceutical factories, especially the arrangement and assembly of complex packaging items, is basically manual operation, which is difficult to ensure the unity and stability of packaging, and may cause pollution to the packaged products. Even if some pharmaceutical companies use packaging machinery, it is only applied to a certain link of the whole packaging chain. For example, mechanical packaging is used for the first stage of packaging, and manual packaging is used for the second stage of packaging. Therefore, improving the automation level and quality level of the whole packaging chain is a very important link for modern pharmaceutical enterprises to implement GMP. Each manipulator of the real modern packaging machinery shall be controlled by computer and has high resolution of material and thickness. The diversification of mechanical functions and the development of pharmaceutical products have tended to be refined and diversified. There are fewer and fewer single variety and large batch products, while multi variety and small batch products have increasingly become the mainstream. Under the changing trend of the general environment, only packaging machines with diversified and multiple switching functions that can adapt to a variety of packaging materials and mold replacement can meet the needs of the market. For example, on a blister packaging machine, both “aluminum plastic” packaging and “aluminum aluminum” packaging can be carried out, with simple switching and less molds to be replaced. The time to replace the mold is generally 1 ~ 2 hours. Such a long time can not meet the requirements of multi variety and small batch production
standard modularization of structural design for traditional industrial design, if you want to launch a new model, you need to do a lot of heavy work and rely on new equipment to recover the high design cost, thus raising the price of the new model. The future design should adopt the design concept of standardization and modularization, make full use of the modular design of the original model, convert it into a new model in a short time, and control the price of the new model within a more reasonable range. The intelligent control system of control
function is not only the brain of mechanical equipment, but also the core device to issue action instructions. Pharmaceutical packaging machinery manufacturers generally use programmable logic controller (PLC controller), which does not have the powerful functions of industrial computer (PC). For most traditional mechanical control equipment, the use of PLC is appropriate, because the number of control parameters is limited, and many places still use mechanical control. For example, torque control uses mechanical clutch to protect the motor from overload. However, with the improvement of equipment automation, there are more and more computer control equipment. The number of various sensing components, detection components, control components and actuator applied to the equipment is very large. At this time, PLC can not manage and control so many parameters, and industrial PC will be the best choice
