Development status of the hottest plastic hollow c

Development status of plastic hollow containers

1. There are attractive business opportunities in the plastic beverage bottle Market

the application market of plastic packaging containers has broad prospects. Among them, there are attractive business opportunities in the beverage industry, and the demand for plastic containers used in beverages such as soda, fruit juice, vegetable juice, etc. is increasing day by day. According to the survey, China's beverage output in 2004 was nearly 20.24 million tons, and the annual growth rate in recent years has exceeded 20%

the development of polypropylene transparent packaging bottles has become a hot spot in the plastic packaging industry at home and abroad in recent years. With the successful development of transparent modifier nucleating agent, adding 0.1% to 0.4% sorbitol xylene (benzaldehyde) nucleating agent (such as mil lad3988 of American merican company) to ordinary PP, high transparent PP packaging can be produced by blow extrusion, blow drawing, injection, extrusion and other methods. This product can be widely used as beverage bottles (cups), heat-resistant containers, food and drug bottles, etc. because its price is cheaper than pet, PS, ABS, PE, it has a broad market prospect

2. The application of beer plastic packaging bottles has been in the spring

China is a large beer production country, with an annual output of 23.86 million tons, ranking first in the world. It is calculated that such a high output makes China need 25-30 billion beer bottles every year. Because the polyester bottle is light and can avoid the danger of explosion, it has a broad market space in replacing glass bottles. However, beer is different from ordinary carbonated beverages. Even a small amount of oxygen entering the packaging container will change the taste of beer, and the loss of CO2 in beer will also affect the characteristics of foam. Moreover, 95% of beer in China is produced by pasteurization, which requires that the packaging bottle not only have good barrier property, but also be able to withstand the temperature of 62~67 ℃. Ordinary PET bottles are difficult to meet the requirements of beer for freshness, shelf life and temperature resistance. In order to improve the barrier performance and temperature resistance of PET bottles, the current international common practice is to adopt the coating technology (plasma technology) of PET bottles. Due to the coating of 0.21 mm thick carbon layer on the inner wall of the bottle, the permeability of PET bottles is almost the same as that of glass, and it can also withstand the high temperature during sterilization

in addition, polyethylene naphthalate (pen) bottles that have appeared in recent years have also attracted the attention of the packaging industry and are entering the beer packaging industry. The molecular structure of pen is similar to that of pet. Due to the substitution of naphthalene ring for benzene ring, pen has excellent impermeability, UV resistance linearity and heat resistance (the thermal change temperature of amorphous pen is 100 ℃, while that of pet is only 70 ℃), so pen bottle can be used as an excellent beer packaging container. However, pen resin cannot be self-sufficient in China at present, so it can only be imported from abroad, and the price of imported resin is five times that of pet, which seriously hinders the application of pen. However, China is rich in coal tar (naphthalene can be separated) resources, that is, it has unique conditions to realize the industrial production of pen. It is believed that in the near future, pen bottles will enter the field of beer packaging in a large number in our Congress

3. Market of drinking water bottles (barrels)

at present, the output of bottled water in China has reached 5.54 million tons, and after years of competition, it has formed a large-scale 8. In recent years, defective parts have been screened out in advance. They put forward higher and higher requirements for the quality of the packaging bottles they use. Therefore, drinking water bottles have a bright market prospect in China

in addition, in recent years, with the improvement of people's living standards, purified drinking water has entered thousands of households in China, and the demand has increased year by year. At present, PC and pet buckets are the main 5-gallon drinking buckets on the market. According to statistics, there were more than 100 production lines of PC barrels in China in 2003. Based on the production capacity of each production line of about 200000, the output of drinking water barrels in China in 2003 reached more than 20 million

4. The development prospect of pharmaceutical packaging bottles is broad.

according to relevant statistics, the annual output value of pharmaceutical packaging in China is about 15billion yuan, which has become an important branch in the field of packaging in China. With the reform of China's medical universal material testing machine, which belongs to the system of high-precision and high-performance testing equipment, and the increase of the types of drugs, the packaging of drugs has developed from the original paper bags, plastic bags, glass bottles to the current polyethylene bottles, polypropylene bottles, polyester bottles, aluminum-plastic packaging and strip packaging, thus reversing the backward situation of China's drug packaging
