In-depth analysis of the development status of PET bottles in my country

my country's polyester containers are currently mainly limited to biaxially oriented polyester blow-molded bottles. my country's biaxially stretched polyester blow molding bottle started late in the plastic packaging industry, but since the introduction of the injection stretch blow PET bottle production line from Japan in the 1980s, it has achieved good results in beverage packaging represented by cola , and then introduced a large number of foreign advanced injection stretch blow PET bottle production equipment, and on the basis of digesting foreign advanced technology, developed a two-step PET stretch blow molding machine with independent intellectual property rights, suitable for my country's national conditions, and simple structure , It is used in conjunction with a universal injection machine to blow PET biaxially stretched bottles using the PET preforms made by the universal injection machine. Among the domestic two-step biaxially oriented PET blow molding machines, some models can not only produce ordinary PET biaxially oriented bottles, but also heat-resistant biaxially oriented PET bottles. The volume of the products that can be produced basically covers Imported equipment can produce a vast field from tens of milliliters of vials to 5-gallon vats. These simple blow molding machines not only have the advantages of low cost and strong maneuverability, but also can produce biaxially oriented PET blowing bottles with good quality and good practicability when properly controlled. Therefore, they have been generally recognized by the plastic processing industry at home and abroad. In addition to a large number of domestic use, some of them have been exported. Although there are still gaps between these equipment and imported advanced equipment, such as low production efficiency, poor degree of automation, and poor dimensional accuracy of products, for some applications with particularly strict requirements (such as the packaging of Coca-Cola, Pepsi and other products), its There are still some difficulties in application. In addition, the production equipment for multi-layer co-blown PET bottles has yet to be developed in China, but the development and utilization of the domestic two-step biaxially oriented PET bottle blowing machine has played a huge role in promoting the rapid development of PET bottle production. . At present, my country's PET bottle production enterprises have advanced automatic PET bottle production lines manufactured by well-known companies in the world (such as the automatic PET bottle production lines of Japan's ASB Company and Aokigu Company, and the automatic PET bottle production lines of French SEDEL Company. production line and the full-automatic PET bottle production line of Italian SIPA company), at the same time, there are also a large number of small and medium-sized enterprises that use various simple and practical bidirectional PET bottle blowing machines with different degrees of automation designed and manufactured in my country. Unprecedented flowers blooming, thriving situation.
