Types and uses of PET plastics

- Jan 05, 2019-

The large-scale industrialization of PET in China started in the early 1980s, and it has grown stronger than in the mid-1990s. At present, the production capacity has exceeded 20 million tons, becoming the world's largest producer and consumer of PET, and the current status and forecast of PET in China. As follows: PET for non-fibrous use was first introduced by Kodak as a substrate for photographic film. Since the mid-1980s, Coca-Cola introduced this variety into the field of beverage packaging. Since then, non-fiber PET has developed rapidly and has been developed. Bottles, membranes, sheets, engineering plastics, packing belts (plastic strips), etc., only for food grade bottles with PET chips for mineral water, carbonated drinks, hot canned drinks, white wine bottles and beer bottles And so on. The global PET production capacity for packaging in 2005 reached 14.5 million tons. China's packaging and non-fibrous PET started late, but it is growing rapidly. In 2005, China's bottle PET production capacity reached 3.1 million tons, and the output reached 1.7 million tons, of which 1.2 million tons were sold domestically and 500,000 tons were exported. China's packaging PET production still has a large room for development (currently 1.3KG/person, 17KG/person in the US, 20KG/person in Europe), and its growth rate is expected to be 15%/year, which means The production capacity at the end of the “Eleventh Five-Year Plan” will be close to 6.5-7 million tons/year. PET (polyethylene terephthalate) has been rapidly replaced by many chemical fibers since it was industrialized by DuPont in 1953 due to its good physical processing properties and cost reduction due to the cost reduction brought about by large industrial production. Other varieties have now become the largest group of synthetic fibers.

Since 2003, global PET production capacity has expanded at an average annual rate of 9%. In 2005, the production capacity has reached 54.7 million tons, and the output in 2005 was 41 million tons. According to PCI, by 2008, global PET production capacity will be It has reached 67 million tons and the output is 50 million tons. At present, the product range of PET has also expanded from the original polyester staple fiber to the current series of polyester staple fiber, polyester filament, polyester bottle, polyester film, non-woven fabric, engineering plastics and composite multifunctional products. There are thousands of kinds of products, and the product series is also developed from the initial 100% short fiber to the balanced development of multiple varieties.
