With the development of the packaging industry, people in the pharmaceutical packaging involved in the increasingly stringent requirements of plastic film, not only thin, and its barrier, transparency and so put forward a high performance requirements. Because pharmaceutical packaging directly involves the safety of the human body, "sterile" and "antibacterial" film in this context has been widely concerned.
In spite of this, GMP has a very stringent requirement for a pharmaceutical production environment, but it is still difficult to achieve absolute sterility during the production and packaging of dosage forms. Therefore, in order to extend the shelf life of drugs to ensure the safety of drugs, in accordance with the GMP requirements, the use of antibacterial polymer packaging films and other materials for drug packaging to inhibit bacterial contamination, pharmaceutical packaging is still the general trend.
Medical use of a wide range of plastic packaging film, not only for tablets, powder, granular pharmaceutical packaging, can also be used for paste, liquid carton packaging, gaskets and packaging drugs and medical equipment used, shrink film has been used for film, Stretch film, multi - layer composite film. In the pharmaceutical packaging, glass bottles, plastic bottles are gradually being replaced by plastic film, especially medical liquid plastic packaging, such as infusion bags, plasma bags and other development more quickly.
According to the US industrial market research firm FreedoniaGrouplnc. Made a survey, from 1997 to 2007, the global pharmaceutical packaging demand an average annual growth rate of 4.3%. According to the European drug packaging market research published in the UK market intelligence show that in the European packaging market, sales of $ 324.6 million in packaging bags in China, 28%. In China's annual output value of 15 billion yuan, the average annual growth rate of more than 10% of the pharmaceutical packaging industry. In recent years, the proportion of plastic products in China, pharmaceutical packaging is rapidly. Data show that China's aluminum tablets, plastic packaging has increased from 10% in 1990 to upgrade to the current 40%, medical film plastic film has become a hot new development. It is expected that in 2005 the demand for pharmaceutical tablets and plastic packaging will increase to $ 400 million. There are many kinds of medical plastic film, mainly polyethylene, polypropylene, polyester, PEN (polyethylene naphthalate) PA, polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride, computer, and the new development Of the ring copolymer (COC), which widely used the largest amount of polyolefin. Raw material diversification 1, PE polyethylene film company, according to market conditions, PE medical plastic packaging film, plastic film one of the fastest growing varieties, is a Mastio research report. It is expected that the global demand for plastic film in the next few years will be 7% of the average annual growth rate of sports medicine. PE medical film is the largest growth potential of the market, medical supplies bags, to prevent infection, followed by a lining film, small packaging, medical equipment packaging film. At present, there are about 40 medical PE packaging products company, the top five is 1 Clopay company (GriffonCorp "), P1iant company, Maxxin medical supplies company, Rexam medical packaging company and Tallinn health care company, its market share of about 50%. Medical PE film, LLDPE the fastest growing volume in 2003 LLDPE medical accounts for the total PE medical film market 52% of the film is expected to reach 54% in 2006. LLDPE medical film rapid development of the main reasons Is due to its thickness can be obtained under the same strength than the LDPE film, the film can be obtained in order to save material and reduce costs. In recent years, medical polyethylene film production, each more than 40,000 t years, in the total 39% And MDPE a small amount of market share below 10%. 2, PP metallocene catalyst Ethylene plastic and PP polypropylene film can improve the resistance of radiation embrittlement, can be used for medical equipment packaging.
In recent years, PP modification, in the development of medicinal liquid bags made great progress. Dongguan Bo Chen electronic raw materials, so that the use of medicinal liquid flexible packaging, such as the use of PP bags, after screening, the combination of regular PP and PP flexible elastic block structure, high melting point, the two materials with excellent flexibility and flexibility, good Low and low temperature toughness and higher than the melting point of 121 ° C, because of its density lower than the PVC about 30%, so that the unit cost is similar to PVC.
