Depth analysis of the development status of PET bottles in China

China's polyester container is currently limited to the two-way stretch polyester blow molding bottles. China's polyester bottles in plastic packaging industry started late, but since 1980s, imported from Japan PET injection stretch blow bottle production line in which coke as the representative of the beverage packaging and achieved good results, then the introduction of a large number of foreign advanced injection blowing PET bottle production equipment, based on advanced technology digestion of foreign countries, developed two step PET stretch blow molding machine with independent intellectual property rights, for the situation of our country, it has the advantages of simple structure, and with the use of general injection machine, use the PET bottle of general injection machine manufacturing, blowing PET biaxially oriented bottles. The domestic two steps of biaxial stretching PET bottle blowing machine, some models can not only the production of ordinary PET biaxially oriented bottles, but also the production of biaxially oriented heat-resistant PET bottle volume, can produce the product basically covers the import of equipment that can be produced from a few ml vials to 5 gallon bucket and broad fields. These simple type bottle blowing machine not only has the advantages of low cost and flexibility, but also can produce the appropriate control of biaxial stretching PET excellent quality, good practical blowing, so it has been widely recognized at home and abroad of plastic processing industry, in addition to a large number of domestic use, has been part of export. Despite the low efficiency and poor automation, product size precision gap still exists between these devices and imported advanced equipment, strict requirements for some applications (such as Coca-Cola, Pepsi and other products packaging), its application still has certain difficulty. In addition, a total of multilayer blow molded PET bottle production equipment in China has yet to be developed, but the domestic two steps of biaxial stretching PET blowing machine utilization to promote the rapid development of PET bottle production has played an important role in promoting, huge. At present, China's PET bottle production enterprises both with automatic production line manufacturing various well-known enterprises in the world's most advanced PET bottles (such as Japan ASB company, Aoki company automatic PET bottle production line, the French company SEDEL automatic PET bottle production line and Italy SIPA automatic PET bottle production line) of large enterprises, at the same time, there are a lot of using our own design and manufacture of various degree of automation, simple and practical bidirectional PET bottle blowing machine for small and medium enterprises, showing a hitherto unknown, thriving situation of a hundred flowers contend in beauty.

At present our country PET bottle production industry, the largest production enterprises are the backbone of Zhuhai Zhongfu and Shanghai Zijiang group, respectively, occupy the domestic market share of about 30% bottles of PET and 20%. Zhuhai Zhongfu group is one of the earliest access to Coca-Cola, PET bottle manufacturer Pepsi Co approved in 2001, the group of PET bottle production reached 3 billion 200 million, of which the hot filling of 700 million, sales reached 2 billion 340 million yuan, with more than and 30 factories in the country. Shanghai Zijiang group in recent years has developed rapidly, in the country's holding company has grown to 15, occupy Wuhan, Zhengzhou, Tianjin, Changchun, Kunshan and Chengdu market, with an annual output of 120 million PET hot filling bottle new has been put into operation, in 2002 to invest and build factories in Shanghai, Guangzhou, Chengdu, Beijing etc. and hot filling bottles of production capacity reached 485 million.

With the rapid development of PET bottles, the production of bottle grade PET resin has been developed rapidly in china. According to reports, in 1995 the amount of PET resin bottles of 100 thousand T, of which the domestic production of T, by the year of 2000, the amount of bottle grade PET resin in China is 520 thousand T, the domestic production capacity has reached t. In addition to the rapid growth of the quantity, quality has greatly improved, bottle grade PET resin Yizheng chemical fiber, Shanghai Far East, Changzhou Huayuan companies have obtained the recognition of Coca Cola Co.
