Plastic and glass in the packaging of the hottest

Plastics and glass in the packaging of drugs and cosmetics (I)

since the reform and opening up, the national living standard has been improving day by day, and the demand for medical care and non essential consumer goods has also been increasing, thus driving the development of the pharmaceutical industry and cosmetics industry. In these two industries, plastic and glass are the most common packaging materials. They play different roles in the pharmaceutical and cosmetic industries

current situation of medicine and cosmetics

China has more than 6000 pharmaceutical production enterprises. In recent years, the pharmaceutical industry has developed rapidly. The output of chemical drugs has reached more than 400000 tons, a total of more than 1300 varieties, more than 4000 preparations of chemical drugs, and the output of chemical APIs has ranked second in the world

bioengineering drugs, which represent the latest technological achievements of the world's pharmaceutical development, have also developed rapidly in China. Among the dozens of bioengineering drugs that have been commercialized internationally, China has been able to produce nearly 20 varieties, with an annual output value of nearly 3billion yuan. Such as hepatitis B antigen genetic engineering vaccine, genetic engineering artificial insulin, interferon, colony stimulating factor, interleukin, erythropoietin, etc

since 2000, the national pharmaceutical production situation has been very good, and the pharmaceutical industry has developed to a new stage of "improving quality, scale and level, and improving economic efficiency". The pharmaceutical industry will continue to maintain double-digit growth, and the profit growth rate of the whole industry will reach about 11%

20 years ago, the foundation of China's chemical industry was very weak. There were less than 200 cosmetic enterprises in the country, and the vast majority of them were produced in manual workshops, with only limited varieties such as fragrant powder, snow cream, toilet water and clam oil. After 1978, China's cosmetics industry has mushroomed and flourished. By the end of 2000, more than 4000 enterprises had obtained cosmetics production licenses, and the gross domestic product of the cosmetics industry increased at an average rate of 15% - 20% per year, which was far higher than the annual growth rate of the national economy and light industry

the cosmetics industry is an industry with low investment, quick effect and high tax revenue. It has made remarkable achievements in creating benefits for the national economy and earning foreign exchange through export

over the past 20 years, although China's cosmetics industry has made great progress, compared with today's developed countries, China's cosmetics consumption is still at a low level. At present, the per capita consumption of cosmetics in China is only 20 yuan (about $2.50), while that in developed countries is about 35-70 dollars

Application and development prospects

with the rapid development of China's pharmaceutical and cosmetic industry, the use of glass bottles and plastic bottles has increased year by year. However, the relative proportion of glass bottles and plastic bottles used in the two industries will decrease year by year. The main alternative packaging materials are plastic flexible packaging, aluminum foil packaging and aluminum plastic composite packaging

1. the traditional glass bottle is mainly made of calcium sodium glass, which is blown manually or mechanically in a glass furnace, and the process is relatively traditional. Due to the rising price of glass raw materials, high energy consumption and gradually rising production costs; In the manufacturing process of glass, dust, waste water, noise and other environmental pollution will be produced. Therefore, the profits of glass bottle production enterprises are generally low, which restricts the new technological transformation of enterprises. Therefore, the application of glass in pharmaceutical packaging materials will gradually be replaced by plastic in many aspects

at present, the development of using computer CAD to design glass bottle mold, computer automatic control of glass furnace and strengthening and lightweight technology has improved the quality of glass bottles and reduced the weight. Due to its unique performance, glass is still the main packaging container for injections, infusion, alcohol and medicinal liquor in terms of drug packaging, and its consumption accounts for about 10% of drug packaging

glass still plays an important role in cosmetics packaging. Especially in the packaging of high-end cosmetics, such as high-end perfume, glass bottles still have great advantages. Using lightweight technology to reduce the wall thickness of the glass, reduce the weight, increase the transparency and surface finish, and carry out sanding process treatment, color painting, color printing (up to 7 ~ 8 colors), engraving, etc. on the surface of the glass, which can improve the quality of the glass bottle by 2 heating furnace: Φ 95mm ×Φ 75mm ×Φ 150mm added value makes the cosmetics and perfume that use this kind of craft glass bottle ③ to push the new plastic film horizontally into the central package of the oil seat not only have the function of beauty, but also have the function of craft decoration, elegant and luxurious, and play the role of beautifying life. This is unmatched by plastic bottles

most of the packaging of medium and low-grade ordinary cosmetics uses plastic bottles. He hopes that both sides can further strengthen cooperation and replace them with plastic bags or plastic tubes. Glass bottles account for no more than 8% of cosmetic packaging containers

2. Plastic bottles are hollow containers made of plastic packaging through various processing methods. It is light in quality and low in price, easy to form large-scale production, and can be made into all kinds of sizes and transparent bottles. With the help of this material technology, it can be used in the "a-cover" shell, opaque and various colored bottles of the new generation of notebook computers. The printing performance of plastic bottles is very good. The instructions, labels and bar codes can be directly made on the surface of plastic bottles by means of heat transfer printing, inkjet, printing and other methods. Plastic bottles have become the most important packaging containers for drugs and cosmetics because of their excellent properties

drugs packaged in plastic bottles are mainly solid tablets, pills, capsules and powders of oral preparations, as well as liquid solutions and emulsions. Plastic bottles used for drug packaging are mainly made of polyvinyl chloride (PVC), polyethylene, polypropylene, polystyrene and other materials
